T1600 Router Description

The T1600 Core Router is a complete routing system that provides Gigabit Ethernet,

SONET/SDH, and other high-speed interfaces for large networks and network applications, such as those supported by Internet service providers (ISPs). The T1600 router accommodates up to eight Flexible PIC Concentrators (FPCs), each of which can be configured with a variety of network media types. The router provides up to 800 gigabits per second (Gbps), full duplex (1600 Gbps of any-to-any, nonblocking, half-duplex) switching.

The router architecture cleanly separates control operations from packet forwarding operations. This design eliminates processing and traffic bottlenecks, permitting the router to achieve high performance.

• Control operations in the router are performed by the host subsystem, which runs Junos operating system (Junos OS) to handle routing protocols, traffic engineering, policy, policing, monitoring, and configuration management.

• Forwarding operations in the router are performed by the Packet Forwarding Engines, which consist of hardware, including ASICs, designed by Juniper Networks.

Application-specific integrated circuits (ASICs) are a definitive part of the router design; they enable the router to achieve data forwarding rates that match current fiber-optic capacity. The T1600 router provides up to a total of 1600 million packets per second

(Mpps) of forwarding.

T1600 Component Redundancy

The T1600 Core Router is designed so that no single point of failure can cause the entire system to fail. The following major hardware components are redundant:

• Switch Interface Boards (SIBs)—The T1600 router has five SIBs.

See

“T1600 Switch Interface Board (SIB) Description” on page 127

• Host subsystem—The host subsystem consists of a Routing Engine functioning together with a control board. The router can have one or two host subsystems. If two host

T1600 Core Router Hardware Guide subsystems are installed, one functions as the master and the other functions as the backup. If the master host subsystem (or either of its components) fails, the backup can take over as the master. To operate, each host subsystem requires a Routing Engine installed in an adjacent slot to a control board.

If the Routing Engines are configured for nonstop active routing, the backup Routing

Engine automatically synchronizes its configuration and state with the master Routing

Engine. Any update to the master Routing Engine state is replicated on the backup

Routing Engine. If the backup Routing Engine assumes mastership, packet forwarding continues through the router without interruption. For more information about nonstop active routing, see the High Availability Feature Guide .

NOTE: Nonstop active routing is supported for standalone T1600 routers in Junos OS Release 8.5 and later. Nonstop active routing is supported for

T1600 routers in a routing matrix in Junos OS Release 10.0 and later.

See

“T1600 Host Subsystem Description” on page 43

• SONET Clock Generators (SCGs)—The router has a standard configuration of one

SCG. A second can be purchased to function as backup. If one SCG fails, the other becomes the master SCG. Mastership of the SCGs is independent of the host subsystem, so routing functions are not affected.

See

“T1600 SONET Clock Generators Description” on page 30

• Power supplies—The router has two power supplies, which share the load evenly. If one power supply fails, the other power supply can provide full power to the router indefinitely.

See

“T1600 Power System Description” on page 113 .

• Cooling system—The cooling system has redundant components, which are controlled by the host subsystem. If one of the fans fails, the host subsystem increases the speed of the remaining fans to provide sufficient cooling for the router indefinitely.

“T1600 Cooling System Description” on page 39

System Architecture Description for T Series Routers

The T Series Core Routers have two main architectural components:

• Routing Engine—One or more Routing Engines provide Layer 3 routing services and network management.

• Packet Forwarding Engines—These high-performance, ASIC-based components provide

Layer 2 and Layer 3 packet switching, route lookups, and packet forwarding.

Chapter 1: System Overview and Architecture

The Routing Engines and the Packet Forwarding Engines perform their primary tasks independently, although they constantly communicate through multiple 100 millions of packets per second (Mbps) links. This arrangement streamlines forwarding and routing control and runs Internet-scale backbone networks at high speeds.

Figure 3 on page 7

shows the relationship between the Routing Engine and the Packet Forwarding Engines.

Routing Engine Functions for T Series Routers on page 7

Packet Forwarding Engine Architecture for T Series Routers on page 8

Routing Engine Functions for T Series Routers

The Routing Engine handles all routing protocol processes, as well as the software processes that control the router's interfaces, the chassis components, system management, and user access to the router. The routing and software processes run on top of a kernel that interacts with the Packet Forwarding Engine.

The Routing Engine constructs and maintains one or more routing tables (see

Figure 4 on page 7 ). From the routing tables, the Routing Engine derives a table of active

routes, called the forwarding table, which is then copied into the Packet Forwarding

Engine. The design of the ASICs allow the forwarding table in the Packet Forwarding

Engine to be updated without interrupting forwarding performance.

Figure 4: Control Packet Handling for Routing and Forwarding Table Updates

T1600 Core Router Hardware Guide

The Routing Engine includes the following functions and features:

• Processing of routing protocol packets—The Routing Engine handles all packets that concern routing protocols, freeing the Packet Forwarding Engine to handle only packets that represent Internet traffic.

• Software modularity—Because each software process is devoted to a different function and uses a separate process space, the failure of one process has little or no effect on the others.

• In-depth Internet functionality—Each routing protocol is implemented with a complete set of Internet features and provides full flexibility for advertising, filtering, and modifying routes. Routing policies are set according to route parameters (for example, prefix, prefix lengths, and BGP attributes).

• Scalability—Junos OS routing tables have been designed to hold all the routes in current networks with ample capacity for expansion. Additionally, Junos OS can efficiently support large numbers of interfaces and virtual circuits.

• Management interface—Different levels of system management tools are provided, including the Junos OS command-line interface (CLI), the Junos XML management protocol, the craft interface, and SNMP.

• Storage and change management—Configuration files, system images, and microcode can be held and maintained in primary and secondary storage systems, permitting local or remote upgrades.

• Monitoring efficiency and flexibility—The router supports functions such as alarm handling and packet counting on every port, without degrading packet-forwarding performance.

Packet Forwarding Engine Architecture for T Series Routers

The Packet Forwarding Engines provide the Layer 2 and Layer 3 packet switching, forwarding, and route lookup functions. The Packet Forwarding Engines are implemented in ASICs that are physically located on the FPCs and the PICs. To ensure the efficient movement of data, the router is designed so that ASICs on the hardware components handle the forwarding of data.

•

Packet Forwarding Engine Components on page 9

•

Data Flow on page 9

Chapter 1: System Overview and Architecture

Packet Forwarding Engine Components

Each Packet Forwarding Engine consists of the following components:

• Layer 2/Layer 3 Packet Processing ASIC, which performs Layer 2 and Layer 3 encapsulation and decapsulation, and manages the division and reassembly of packets within the router.

• Queuing and Memory Interface ASICs, which manage the buffering of data cells in memory and the queueing of notifications.

• T Series Internet Processor, which provides the route lookup function.

• Switch Interface ASICs, which extract the route lookup key and manage the flow of data cells across the switch fabric.

Media-specific ASICs on the PICs perform control functions tailored to the PIC media types.

Data Flow

To ensure the efficient movement of data, the router is designed so that ASICs on the hardware components handle the forwarding of data. Data flows through the router in the following sequence (see

Figure 5 on page 9

Figure 5: Data Flow Through the Router

T1600 Core Router Hardware Guide

Packets arrive at an incoming PIC interface.

The PIC passes the packets to the FPC, where the Layer 2/Layer 3 Packet Processing

ASIC performs Layer 2 and Layer 3 parsing and divides the packets into 64-byte cells.

The Switch Interface ASIC extracts the route lookup key, places it in a notification, and passes the notification to the T Series Internet Processor. The Switch Interface

ASIC also passes the data cells to the Queuing and Memory Interface ASICs for buffering.

The Queuing and Memory Interface ASICs pass the data cells to memory for buffering.

The T Series Internet Processor performs the route lookup and forwards the notification to the Queuing and Memory Interface ASIC.

The Queuing and Memory Interface ASIC sends the notification to the Switch Interface

ASIC facing the switch fabric, unless the destination is on the same Packet Forwarding

Engine. In this case, the notification is sent back to the Switch Interface ASIC facing the outgoing ports, and the packets are sent to the outgoing port without passing through the switch fabric (see Step

The Switch Interface ASIC sends bandwidth requests through the switch fabric to the destination port. The Switch Interface ASIC also issues read requests to the Queuing and Memory Interface ASIC to begin reading data cells out of memory.

The destination Switch Interface ASIC sends bandwidth grants through the switch fabric to the originating Switch Interface ASIC.

On receipt of each bandwidth grant, the originating Switch Interface ASIC sends a cell through the switch fabric to the destination Packet Forwarding Engine.

10.

The destination Switch Interface ASIC receives cells from the switch fabric. It extracts the route lookup key from each cell, places it in a notification, and forwards the notification to the T Series Internet Processor.

11.

The T Series Internet Processor performs the route lookup, and forwards the notification to the Queuing and Memory Interface ASIC.

12.

The Queuing and Memory Interface ASIC forwards the notification, including next-hop information, to the Switch Interface ASIC.

13.

The Switch Interface ASIC sends read requests to the Queuing and Memory Interface

ASIC to read the data cells out of memory, and passes the cells to the Layer 2/Layer

3 Packet Processing ASIC.

Chapter 1: System Overview and Architecture

14.

The Layer 2/Layer 3 Packet Processing ASIC reassembles the data cells into packets, adds Layer 2 encapsulation, and sends the packets to the outgoing PIC interface.

15.

The outgoing PIC sends the packets out into the network.

Outstanding Issues with the T1600 Router

This topic lists outstanding hardware issues with the T1600 Core Router.

• To support the 10-Gigabit Ethernet LAN/WAN PIC with Oversubscription and SFP+

(model number PD-5-10XGE-SFPP) in the T1600-FPC4-ES (part number 710-013037),

REV 13 and later is required.

T1600-FPC4-ES (part number 710-013037), REV 12 and earlier does not support the

10-Gigabit Ethernet LAN/WAN PIC with Oversubscription and SFP+ (model number

PD-5-10XGE-SFPP).

• When the C8000-RE Routing Engine is installed, the LEDs for the ETHERNET ports on the connector interface panel (CIP) have the following issues:

• Model number RE-DUO-C1800-8G (part number 740-026941 Rev 7)—The activity

LEDs, labeled ACT0 and ACT1 , for the ETHERNET ports on the connector interface panel (CIP) are always steadily green, even when no cables are connected to the ports.

For RE-DUO-C1800-8G (part number 740-026941 Rev 8) and above, the CIP LED behavior is as described in the T1600 Core Router Hardware Guide .

• Model numbers RE-DUO-C1800-8G and RE-DUO-C1800-16G—The LEDs labeled

GRN = 100M and YEL= 10M is always yellow, but the speed is always a 100-Mbps connection.

• After powering on or off a power supply, wait at least 60 seconds before turning it back off or on again.

• After a power supply is powered on, it can take up to 60 seconds for status indicators—such as LEDs on the power supply, show chassis commands, and messages on the craft interface LCD —to indicate that the power supply is functioning normally.

Ignore error indicators that appear during the first 60 seconds.

T1600 Chassis Description

The T1600 Core Router chassis is a rigid sheet metal structure that houses all the other

T1600 router components (see

Figure 6 on page 22

and

Figure 7 on page 23 ). The chassis

measures 37.45 in. (95.1 cm) high, 31 in. (78.7 cm) deep, and 17.43 in. (44.3 cm) wide. The chassis can be installed into many types of racks or cabinets.

The chassis includes the following features (see

Figure 6 on page 22

and

Figure 7 on page 23 ):

• Front-mounting flanges for mounting in a four-post rack or cabinet or front-mounting in an open-frame rack.

• Center-mounting metal brackets for center-mounting in an open-frame rack.

• Handles on each side to facilitate positioning the router in the rack. Do not use the handles to lift the router.

• Two electrostatic discharge (ESD) points (banana plug receptacles), one front and one rear.

CAUTION: Before removing or installing components of a router, attach an ESD strap to an ESD point and place the other end of the strap around your bare wrist. Failure to use an ESD strap could result in damage to the router.

T1600 Midplane Description

The midplane is located in the center of the chassis and forms the rear of the FPC card cage (see

Figure 8 on page 24 ). The FPCs install into the midplane from the front of the

T1600 Core Router Hardware Guide chassis, and the SIBs, Routing Engines, and control boards and SCGs install into the midplane from the rear of the chassis. The power supplies and cooling system components also connect to the midplane.

The midplane performs the following major functions:

• Data path—Data packets are transferred across the midplane from the Packet

Forwarding Engine on the originating FPC to the SIBs, and from the SIBs across the midplane to the Packet Forwarding Engine on the destination FPC.

See

“Packet Forwarding Engine Architecture for T Series Routers” on page 8 .

• Power distribution—The router power supplies are connected to the midplane, which distributes power to all the router components.

See

“T1600 Power System Description” on page 113 .

• Signal path—The midplane provides the signal path to the FPCs, SIBs, Routing Engines,

CB, and other system components for monitoring and control of the system.

For T1600 routers connected to a TX Matrix Plus router, you can use the optional rear cable management system to organize, support, and provide strain relief for the cables connected to the TXP-T1600 or TXP-LCC-3D SIBs, and the cables connected to the

LCC-CBs. The rear cable management system consists of one cable management arm.

The cables are routed to the left side of the T1600 router, and then toward the top of the chassis, where you can route the cables to the TX Matrix Plus router. The cable

T1600 Core Router Hardware Guide management system adds 9.5 in. (24.1 cm) to the depth of the T1600 chassis, and 2.4 in.

(6.2 cm) to the left side of the chassis.

• The optional rear cable management system (model number CBL-MGR-TXP-LCC) supports the TXP-T1600 configuration and fiber-optic array cables only (see

Figure 10 on page 26 ).

• The LCC rear cable management system (model number CBL-MGR-TXP-3D-LCC) can be used for any configuration including TXP-T1600 configuration, TXP-T1600-3D configuration, TXP-T4000-3D configuration, and TXP-Mixed-LCC-3D configuration.

See the TX Matrix Plus Router Hardware Guide for instructions on installing and using the

The CIP is located at the left side of the FPC card cage, above the front electrostatic discharge point. The CIP is hot-pluggable.

Management Ports

The CIP has two sets of management ports (see

Figure 11 on page 28 ) that you use to

connect the Routing Engines to external management devices. The upper set of ports, labeled HOST 0 , connects to the Routing Engine in slot RE0 ; and the lower set, labeled

HOST 1 , connects to the Routing Engine in slot RE1 . From these management devices, you can use the CLI to configure the router.

Chapter 3: Chassis Components and Descriptions

Each set includes the following ports:

• ETHERNET —Connects the Routing Engine through an Ethernet connection to a management LAN (or any other device that plugs into an Ethernet connection) for out-of-band management. The port uses an autosensing RJ-45 connector to support both 10- and 100-Mbps connections.

• One small LED on the upper left edge of the ETHERNET port, labeled ACT , indicates whether traffic is passing through the port.

• One small LED on the lower left edge of the ETHERNET port indicates the connection in use: the yellow LED lights for a 10-Mbps connection, and the green LED lights for a 100-Mbps connection.

NOTE: When an RE-C18000 is installed, the connection LED is always yellow for both a 10-Mbps connection and 100-Mbps connection.

• CONSOLE —Connects the Routing Engine to a system console through an RS-232

(EIA-232) serial cable.

• AUXILIARY — Connects the Routing Engine to a laptop, modem, or other auxiliary device through an RS-232 (EIA-232) serial cable.

T1600 Alarm Relay Contacts

The CIP has two alarm relay contacts for connecting the router to external alarm devices

(see

Figure 11 on page 28 ). Whenever a system condition triggers either the red or yellow

alarm on the craft interface, the alarm relay contacts are also activated. The alarm relay contacts are located below the Routing Engine ports. The terminal blocks that plug into the alarm relay contacts are supplied with the router. They accept wire of any gauge between 28-AWG and 14-AWG (0.08 and 2.08 mm

), which is not provided. Use the gauge of wire appropriate for the external device you are connecting.

T1600 Cooling System Description

The cooling system components work together to keep all router components within the acceptable temperature range. The host subsystem monitors the temperature of the router components. When the router is operating normally, the fans function at lower than full speed. If a fan fails or the ambient temperature rises above a threshold, the speed of the remaining fans is automatically adjusted to keep the temperature within the acceptable range. If the ambient maximum temperature specification is exceeded and the system cannot be adequately cooled, the Routing Engine shuts down some or all of the hardware components.

NOTE: The standard fan trays and quiet fan trays are not interchangeable with each other. All fans in the chassis must be either standard fan trays or quiet fan trays.

The cooling system contains the following fan trays:

• One rear fan tray cools the components installed in the rear card cage (the Routing

Engines, control boards, SCGs, and SIBs). The T1600 router supports the following rear fan trays:

• The standard rear fan tray, supported by Junos OS 8.5 and later, contains eight fans.

It has no label and is not interchangeable with the standard front fan trays.

• The quiet rear fan tray, labeled REAR FANTRAY FAN-R-S and supported by Junos

OS 11.1 and later, contains eight fans and is not interchangeable with the quiet front fan trays.

• One upper front fan tray and one lower front fan tray that cool the components installed in the front card cage (the FPCs, PICs, CIP, and midplane). The T1600 router supports the following front fan trays:

• The upper and lower standard front fan trays, each of which contains six fans and has no labels. Both standard fan trays are interchangeable with each other.

• Each quiet front fan tray contains four fans, as indicated by the four fan icons on the faceplate, and is supported by Junos OS 11.1 and later.

NOTE: The quiet upper front fan tray and quiet lower front fan tray are not interchangeable with each other. In addition to the labels, the quiet upper fan tray also has an upward pointing arrow above the four fan icons on the faceplate.

T1600 Host Subsystem Description

The host subsystem provides the routing and system management functions of the router. You can install one or two host subsystems on the router. The host subsystem consists of a Routing Engine and an adjacent control board. To operate, each host subsystem functions as a unit; the Routing Engine requires the corresponding control board, and vice versa.

T1600 Core Router Hardware Guide

NOTE: We recommend that you install two host subsystems for redundant protection. If you install only one host subsystem, we recommend that you install it in slots RE0 and CB0 .

Each host subsystem has three LEDs, located on the upper right of the craft interface, that display its status. In addition, there are LEDs on each Routing Engine and control board.

Documentation

•

•

T1600 Craft Interface Host Subsystem LEDs on page 36

•

T1600 Routing Engine Description

The Routing Engine runs Junos OS. Software processes that run on the Routing Engine maintain the routing tables, manage the routing protocols used on the T1600 Core Router, control the T1600 router interfaces, control some chassis components, and provide the interface for system management and user access to the router.

You can install one or two Routing Engines in the router. The Routing Engines install into the upper rear of the chassis in the slots labeled RE0 and RE1 . Each Routing Engine requires a control board to be installed in the adjacent slot.

RE0 installs below CB0 , and RE1 installs above CB1 . A Routing Engine does not power up without a control board present in the adjacent slot.

If two Routing Engines are installed, one functions as the master and the other acts as the backup. If the master Routing Engine fails or is removed and the backup is configured appropriately, the backup takes over as the master. If the host system is redundant, the backup Routing Engine is hot-removable and hot-insertable, but the master Routing

Engine is hot-pluggable. A Routing Engine that is not redundant requires that you power down the router before replacement.

NOTE: For specific information about Routing Engine components (for example, the amount of DRAM), issue the show chassis routing-engine command.

The ports for connecting the Routing Engine to external management devices are located on the Connector Interface Panel (CIP).

NOTE: If two Routing Engines are installed, they must both be the same hardware model, except during upgrade.

RE-C1800 Components

Each RE-C1800 ( Figure 24 on page 50

) consists of the following components:

• CPU—Runs Junos OS to maintain the routing tables and routing protocols.

• DRAM—Provides storage for the routing and forwarding tables and for other Routing

Engine processes.

• EEPROM—Stores the serial number of the Routing Engine.

• Interfaces for management access—Provide information about Routing Engine status to devices (console, laptop, or terminal server) connected to the management ports located on the CIP.

NOTE: The router's management Ethernet interface em0 is the interface for connecting network devices to the router through the ETHERNET port on the connector interface panel (CIP). Junos OS automatically creates em0 , but you must configure its logical interface, em0.0

, with a valid IP address before you can use em0 as a management port.

Figure 24: RE-C1800

The faceplate of the RE-C1800 contains the following:

• USB port—Provides a removable media interface through which you can install Junos

OS manually. Junos OS supports USB version 1.1 and version 2.0 devices.

• CompactFlash card slot—Provides primary storage for software images, configuration files, and microcode.

• Two solid-state disk (SSD) slots—Provides secondary storage for log files, memory dumps, and rebooting the system if the CompactFlash card fails.

NOTE: DISK2 is not currently supported.

• Reset button—Reboots the Routing Engine when pressed.

• Offline button—Takes the Routing Engine offline when pressed.

• Four LEDs— CF , ONLINE , ONLINE , and ONLINE .

• Extractor clips—Control the locking system that secures the Routing Engine.

Chapter 5: Host Subsystem Components and Descriptions

RE-C1800 Boot Order

The RE-C1800 Routing Engine boots from the storage media in this order: the USB device, then the CompactFlash card (if present), then DISK1 , then the LAN.

• Hard disk—Provides secondary storage for log files, memory dumps, and rebooting the system if the CompactFlash card fails.

• EEPROM—Stores the serial number of the Routing Engine.

• Interfaces for out-of-band management access—Provide information about

Routing Engine status to devices (console, laptop, or terminal server) connected to the Routing Engine ports located on the CIP.

, with a valid IP address before you can use fxp0 as a management port.

The faceplate of the RE-2000 contains the following:

• USB port—Provides a removable media interface through which you can install Junos

OS manually. Junos OS supports USB version 1.0.

• Reset button—Reboots the Routing Engine when pressed.

T1600 Control Boards Description

The T1600 chassis supports up to two control boards. The Routing Engine requires an adjacent control board to provide control and monitoring functions for the T1600 Core

Router. These functions include determining Routing Engine mastership, controlling power and reset for the other T1600 router components, monitoring and controlling fan speed, and monitoring system status.

You can install up to two control boards in the chassis. Control boards install into the upper rear of the chassis in the slots labeled CB0 and CB1 (referred to as CB-0 and CB-1 , top to bottom). If two control boards are installed, one functions as the master and the other as its backup. If the master fails or is removed, the backup restarts and becomes the master.

Each control board requires a Routing Engine to be installed in the adjacent slot.

CB0 installs above RE0 , and CB1 installs below RE1 . Control boards cannot function if a Routing

Engine is not present in the adjacent slot.

If the host system is redundant, the backup control board is hot-removable and hot-insertable, but the master control board is hot-pluggable. A control board that is not redundant is hot-pluggable.

The T1600 router supports the control boards listed in

Table 43 on page 75 .

T1600 FPC Function

FPCs house the PICs that connect the T1600 Core Router to network media. The main function of an FPC is to connect the PICs installed in it to the other T1600 router components. The Packet Forwarding Engine receives incoming packets from the PICs installed on the FPC and forwards them through the switch planes to the appropriate destination port. In a maximum configuration with eight Type 4 FPCs installed, the Packet

Forwarding Engines can forward up to 1600 million packets per second (Mpps) for all packet sizes. The T1600 Core Router provides up to 800 gigabits per second (Gbps), full duplex switching (1600 Gbps of any-to-any, nonblocking, half-duplex switching).

When you install an FPC into a functioning router, the Routing Engine downloads the

FPC software, the FPC runs its diagnostics, and the PICs housed on the FPC, are enabled.

Forwarding on other FPCs continues uninterrupted during this process.

T1600 Core Router Hardware Guide

T1600 FPC Slots

Up to eight FPCs install vertically in the front of the router. The FPC slots are numbered

FPC0 through FPC7 , left to right. If a slot is not occupied by an FPC, an FPC blank panel must be installed to shield the empty slot and to allow cooling air to circulate properly through the router.

T1600 FPC Components

Each FPC consists of the following components:

• FPC card carrier.

• One or two Packet Forwarding Engines, consisting of Layer 2/Layer 3 Packet Processing

ASICs, Switch Interface ASICs, T-series Internet Processor ASICs, and a Memory

Mezzanine Board (MMB) which includes the Queuing and Memory Interface ASICs.

• Each Type 1 FPC has one Packet Forwarding Engine

• Each Type 2 FPC has one Packet Forwarding Engine

• Each Type 3 FPC has two Packet Forwarding Engines

• Each T640-FPC4-ES has one Packet Forwarding Engine

• Each T640-FPC4-1P-ES has one Packet Forwarding Engine

• Each T1600-FPC4-ES has two Packet Forwarding Engines

• Processor Mezzanine Board (PMB), which includes a 300-MHz CPU, system controller,

256 MB of SDRAM, and two Fast Ethernet interfaces.

• Two LEDs, located on the craft interface above the FPC, that display the status of the

FPC.

• FPC online/offline button, located on the craft interface above the FPC.

T1600 FPC Terminology

Regardless of whether you are holding an FPC vertically or horizontally, this document uses the same terms for all four edges of the FPC (see

Figure 30 on page 83 ):

• Faceplate—Edge of the FPC that has slots into which you insert the PICs

• Connector edge—Edge opposite the faceplate; this edge has the connectors that attach to the midplane

• Top edge—Edge at the top of the FPC when it is vertical

• Bottom edge—Edge at the bottom of the FPC when it is vertical

Figure 30: FPC Edges

Chapter 6: Line Card Components and Descriptions

Identifying the T1600 FPCs

Check the label on the faceplate to identify the FPC. For FPCs without a label on the faceplate, check the location of a PIC's offline button and how the PIC is secured to the

FPC. See

T1600 PIC Description

PICs provide the physical connection to various network media types, receiving incoming packets from the network and transmitting outgoing packets to the network. During this process, each PIC performs framing and line-speed signaling for its media type. Before transmitting outgoing data packets, the PICs encapsulate the packets received from the

FPCs. Each PIC is equipped with an ASIC that performs control functions specific to the media type of that PIC.

Chapter 6: Line Card Components and Descriptions

PICs are hot-removable and hot-insertable. You can install up to four PICs in each Type

1, 2, and 3 FPC, one PIC in each T640 Enhanced Scaling FPC4 or Enhanced Scaling

FPC4-IP, and one or two PICs in each T640 Enhanced Scaling FPC4. Type 1 and Type 2

PICs have captive screws at their upper and lower corners. Type 3 PICs have an upper ejector handle and a lower captive screw. Type 4 PICs have an upper ejector handle and a lower ejector handle.

The router supports various PICs, including ATM, Channelized, Gigabit Ethernet, IP Services, and SONET/SDH interfaces. Blank PICs resemble other PICs but do not provide any physical connection or activity. When a slot is not occupied by a PIC, you must insert a blank PIC to fill the empty slot and ensure proper cooling of the system.

T1600 PIC Combination Limitations

In most cases, you can install PICs of different media types on the same FPC as long as the FPC and the router support those PICs. However, configuration rules might limit certain combinations of PICs on some platforms.

Newer Junos OS services for some PICs can require significant Internet Processor ASIC memory. Ethernet and SONET PICs typically do not use large amounts of memory. Gigabit

Ethernet, ATM2, IQ serial PICs, and Multiservices PICs use more. To conserve memory, you can group PICs in the same family together on the same FPC.

8.5

6.1

8.5

105

T1600 Core Router Hardware Guide

If you have different PIC families on a single FPC, review the configuration rules to plan which PICs to install on the FPCs for your router. Consult technical bulletin

PSN-2007-01-023 for information about configuration rules for PIC combinations on the

Juniper Networks Support site at https://www.juniper.net/alerts/ .

When you upgrade to Junos OS Release 7.5 or later, a warning appears if any configuration rules affect your PIC combinations. If you continue the installation, one or more PICs might appear to be online (the LEDs are on), but the Junos OS cannot enable them and they cannot pass traffic. As a workaround, you can:

• Install a Junos OS release that supports the combination.

• Install PICs on a different FPC.

• Remove PICs from the affected FPC.

T1600 Power System Description

The T1600 Core Router has two redundant, load-sharing power supplies, located at the lower rear of the chassis in slots PEM0 and PEM1 (top to bottom).

The power supplies connect to the midplane, which distributes the different output voltages produced by the power supplies to the T1600 router components, depending on their voltage requirements. For each output voltage that the power supply provides, it has either an active circuit breaker or an active current limiter.

NOTE: There are no passive fuses in the router that must be replaced.

Each power supply is cooled by its own internal cooling system. Power supplies are hot-removable and hot-insertable.

The T1600 router supports the power supplies in

Table 68 on page 114 .

NOTE: Redundant power supplies must be the same model number during normal operations.

T1600 Three-Input 240-A DC Power Supply Inputs

The three-input 240-A DC power supply inputs are labeled INPUT 0 , INPUT 1 , and INPUT 2 , from top to bottom. Each input consists of –48 VDC and return—each with its own 80-A circuit breaker. The input mode switch on the faceplate allows you to set the DC power supply to either 2-INPUT or 3-INPUT mode.

3-INPUT mode is required for the T1600 Core

Router.

T1600 Three-Input 240-A DC Power Supply Load Sharing and Fault Tolerance

When the T1600 router is operating normally and both power supplies are switched on, load sharing between them occurs automatically. When one power supply fails or is turned off, the other power supply immediately assumes the entire electrical load for the system. A single power supply can provide full power for as long as the router is operational. At least one power supply needs all three inputs, INPUT 0 , INPUT 1 and INPUT

2 to function properly.

T1600 Switch Interface Board (SIB) Description

SIBs create the switch fabric for the T1600 Core Router. Each T1600 router contains five

SIBs located at the center rear of the chassis in the slots labeled SIB0 through SIB4 (top to bottom). One of the five SIBs acts as a backup to the remaining four SIBs. If a SIB fails, the backup SIB becomes active, and traffic forwarding continues without any degradation.

When the failed SIB is replaced, it becomes the new backup. SIBs are hot-insertable and hot-removable.

The T1600 router supports the SIBs listed in

T1600 Chassis Grounding Cable and Lug Specifications

To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, the router must be adequately grounded before power is connected.

Two pairs of threaded inserts (PEM nuts) are provided on the right rear of the chassis for connecting the router to earth ground. The left pair of grounding points fits M6 screws

Chapter 9: Preparation Overview

(European), and the right pair fits UNC 1/4–20 screws (American). The grounding points are spaced at 0.625-in. (15.86-mm) centers.

You must supply a grounding cable. The grounding cable must be 8-AWG (8.35 mm

), minimum 90°C wire, or as required by the local code.

The accessory box shipped with the router includes one 4-AWG (21.2 mm

2 cable lug that attaches to the grounding cable (see

Figure 56 on page 141

). (The cable lug shown in

Figure 56 on page 141

is also used for the DC power cables.) The accessory box includes two UNC 1/4–20 screws used to secure the grounding cable to the right pair of grounding points.

CAUTION: Before router installation begins, a licensed electrician must attach a cable lug to the grounding cable that you supply. A cable with an incorrectly attached lug can damage the router.

Rack Requirements for the T1600 Router

The router can be installed in many types of racks, including four-post (telco) racks and open-frame racks. An example of an open-frame rack is shown in

Figure 57 on page 142 .

For open-frame racks, center-mounting is preferable to front-mounting because the more even distribution of weight provides greater stability.

The router is designed for installation in a 19-in. rack as defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310-D) published by the Electronics

Components Industry Association ( http://www.ecianow.org/ ).

With the use of adapters, the router can fit into a 600-mm-wide rack, as defined in the four-part Equipment Engineering (EE); European Telecommunications Standard for

Equipment Practice (document numbers ETS 300 119-1 through 119-4) published by the

European Telecommunications Standards Institute ( http://www.etsi.org

). Use approved wing devices to narrow the opening between the rails.

141

T1600 Core Router Hardware Guide

The rack rails must be spaced widely enough to accommodate the router chassis's external dimensions: 37.45 in. (95.1 cm) high, 31 in. (78.7 cm) deep, and 17.43 in. (44.3 cm) wide, excluding the front and rear cable management systems. The outer edges of the mounting brackets extend the width to 19 in. (48.3 cm). The spacing of rails and adjacent racks must also allow for the clearances around the router and rack.

The mounting holes for connecting the mounting brackets to the chassis are spaced

0.984 in. (25 mm) apart.

The chassis height of 37.45 in. (95.1 cm) is approximately 21.4 U. A U is the standard rack unit defined in Cabinets, Racks, Panels, and Associated Equipment (document number

EIA-310-D) published by the Electronics Components Industry Association. You can stack two routers in a rack that has at least 42.8 U (74.9 in. or 1.90 m) of usable vertical space.

The rack must be strong enough to support the weight of the fully configured router, up to 606 lb (275 kg). If you stack two fully configured routers in one rack, it must be capable of supporting about 1212 lb (550 kg).

Figure 57: Typical Open-Frame Rack

142

Always secure the rack to the structure of the building. If your geographical area is subject to earthquakes, bolt the rack to the floor. For maximum stability, also secure the rack to ceiling brackets.

Clearance Requirements for Airflow and T1600 Hardware Maintenance

When planning the installation site, you need to allow sufficient clearance around the rack (see

Figure 58 on page 143 ):

• For the cooling system to function properly, the airflow around the chassis must be unrestricted.

NOTE: If you mount the router in a cabinet, be sure that ventilation is sufficient to prevent overheating.

• For service personnel to remove and install hardware components, there must be adequate space at the front and back of the router. At least 24 in. (61 cm) are required both in front of and behind the router. NEBS GR-63 recommends that you allow at least 30 in. (72.6 cm) behind the rack.

• Additional clearance is required to accommodate the width and depth of the chassis with the optional rear cable management system:

• 2.4 in. (6.2 cm) additional width on the left side of the chassis

• 9.5 in. (24.1 cm) additional depth in the rear of the chassis

T1600 DC Power Distribution

Most sites distribute DC power through a main conduit that leads to frame-mounted DC power distribution panels, one of which might be located at the top of the rack that houses the router. A pair of cables (one input and one return) connects each set of terminal studs to the power distribution panel.

NOTE: All inputs on the DC power supply in slot PEM0 must be powered by dedicated power feeds derived from feed A, and all inputs on the DC power supply in slot PEM 1 must be powered by dedicated power feeds derived from feed B. This configuration provides the commonly deployed A/B feed redundancy for the system.

WARNING: For field-wiring connections, use copper conductors only.

Chapter 10: DC Power Specifications and Requirements

CAUTION: Power cables must not block access to router components or drape where people could trip on them.

CAUTION: You must ensure that power connections maintain the proper polarity. The power source cables might be labeled (+) and (–) to indicate their polarity. There is no standard color coding for DC power cables. The color coding used by the external DC power source at your site determines the color coding for the leads on the power cables that attach to the terminal studs on each power supply.

DC Power Lugs

The accessory box shipped with the T640 router includes eighteen 4-AWG (21.2 mm

) cable lugs for the DC cables that attach to the terminal studs of each power supply (see

Figure 60 on page 153

). the number of DC cables and cable lugs required varies depending on the power supply (see

Table 91 on page 152 ). Each DC power cable requires one cable

lug. One cable lug is also used for grounding the chassis. The cable lugs are dual hole, and sized to fit 1/4-20 UNC terminal studs at 15.86-mm (0.625-in.) center line.

Figure 60: DC Power Cable Lug

CAUTION: Before router installation begins, a licensed electrician must attach a cable lug to the power cables that you supply. A cable with an incorrectly attached lug can damage the router.

T1600 AC Power Cord Specifications

Most sites distribute power through a main conduit that leads to frame-mounted power distribution panels, one of which can be located at the top of the rack that houses the router. An AC power cord connects each power supply to the power distribution panel.

Each AC power supply has a metal wiring compartment that contains the AC terminal block and ground labeled GND . The wye AC terminal block consists of four input terminals labeled L1 , L2 , L3 , and N , from left to right. The delta AC terminal block consists of three input terminals labeled L1 , L2 , and L3 , from left to right.

Detachable AC power cords, each 4.5 m (approximately 14.8 ft) long, are supplied with the router. The AC power cord wires insert into the AC input terminals in the AC terminal block by screwdriver. The plug end of the power cord fits into the power source receptacle for your geographical location.

Determining Transceiver Support and Specifications for M Series and T Series Routers

You can find information about the pluggable transceivers supported on your Juniper

Networks device by using the Hardware Compatibility Tool. In addition to transceiver and connector type, the optical and cable characteristics—where applicable—are documented for each transceiver. The Hardware Compatibility Tool allows you to search by product, displaying all the transceivers supported on that device, or category, displaying all the transceivers by interface speed or type. The Hardware Compatibility Tool is located at https://apps.juniper.net/hct/ .

Some transceivers support additional monitoring using the operational mode CLI command show interfaces diagnostics optics . Use the Hardware Compatibility Tool to determine if your transceiver supports monitoring. See the Junos OS documentation for your device for a description of the monitoring fields.

CAUTION: If you face a problem running a Juniper Networks device that uses a third-party optic or cable, the Juniper Networks Technical Assistance Center

(JTAC) can help you diagnose the source of the problem. Your JTAC engineer might recommend that you check the third-party optic or cable and potentially replace it with an equivalent Juniper Networks optic or cable that is qualified for the device.

Understanding Fiber-Optic Cable Signal Loss, Attenuation, and Dispersion

This topic describes signal loss, attenuation, and dispersion in fiber-optic cable.

•

Signal Loss in Multimode and Single-Mode Fiber-Optic Cable on page 164

•

Attenuation and Dispersion in Fiber-Optic Cable on page 164

Signal Loss in Multimode and Single-Mode Fiber-Optic Cable

Multimode fiber is large enough in diameter to allow rays of light to reflect internally

(bounce off the walls of the fiber). Interfaces with multimode optics typically use LEDs as light sources. However, LEDs are not coherent sources. They spray varying wavelengths of light into the multimode fiber, which reflects the light at different angles. Light rays travel in jagged lines through a multimode fiber, causing signal dispersion. When light traveling in the fiber core radiates into the fiber cladding, higher-order mode loss results.

Together these factors limit the transmission distance of multimode fiber compared with single-mode fiber.

Single-mode fiber is so small in diameter that rays of light can reflect internally through one layer only. Interfaces with single-mode optics use lasers as light sources. Lasers generate a single wavelength of light, which travels in a straight line through the single-mode fiber. Compared with multimode fiber, single-mode fiber has higher bandwidth and can carry signals for longer distances.

Exceeding the maximum transmission distances can result in significant signal loss, which causes unreliable transmission.

Attenuation and Dispersion in Fiber-Optic Cable

Correct functioning of an optical data link depends on modulated light reaching the receiver with enough power to be demodulated correctly.

Attenuation is the reduction in power of the light signal as it is transmitted. Attenuation is caused by passive media components, such as cables, cable splices, and connectors. Although attenuation is significantly lower for optical fiber than for other media, it still occurs in both multimode and single-mode transmission. An efficient optical data link must have enough light available to overcome attenuation.

Dispersion is the spreading of the signal over time. The following two types of dispersion can affect an optical data link:

• Chromatic dispersion—Spreading of the signal over time resulting from the different speeds of light rays.

• Modal dispersion—Spreading of the signal over time resulting from the different propagation modes in the fiber.

For multimode transmission, modal dispersion, rather than chromatic dispersion or attenuation, usually limits the maximum bit rate and link length. For single-mode transmission, modal dispersion is not a factor. However, at higher bit rates and over longer distances, chromatic dispersion rather than modal dispersion limits maximum link length.

Chapter 12: Network Cable and Transceiver Specifications

An efficient optical data link must have enough light to exceed the minimum power that the receiver requires to operate within its specifications. In addition, the total dispersion must be less than the limits specified for the type of link in Telcordia Technologies document GR-253-CORE (Section 4.3) and International Telecommunications Union

(ITU) document G.957.

When chromatic dispersion is at the maximum allowed, its effect can be considered as a power penalty in the power budget. The optical power budget must allow for the sum of component attenuation, power penalties (including those from dispersion), and a safety margin for unexpected losses.

Calculating Power Budget and Power Margin for Fiber-Optic Cables

Use the information in this topic and the specifications for your optical interface to calculate the power budget and power margin for fiber-optic cables.

TIP: You can use the Hardware Compatibility Tool to find information about the pluggable transceivers supported on your Juniper Networks device.

To calculate the power budget and power margin, perform the following tasks:

Calculating Power Budget for Fiber-Optic Cable on page 165

Calculating Power Margin for Fiber-Optic Cable on page 165

Calculating Power Budget for Fiber-Optic Cable

To ensure that fiber-optic connections have sufficient power for correct operation, you need to calculate the link's power budget, which is the maximum amount of power it can transmit. When you calculate the power budget, you use a worst-case analysis to provide a margin of error, even though all the parts of an actual system do not operate at the worst-case levels. To calculate the worst-case estimate of power budget (P

B you assume minimum transmitter power (P

) and minimum receiver sensitivity (P

= P

– P

The following hypothetical power budget equation uses values measured in decibels

(dB) and decibels referred to one milliwatt (dBm):

= P

– P

= –15 dBm – (–28 dBm)

= 13 dB

Calculating Power Margin for Fiber-Optic Cable

After calculating a link's power budget, you can calculate the power margin (P

), which represents the amount of power available after subtracting attenuation or link loss (LL) from the power budget (P

). A worst-case estimate of P

M assumes maximum LL:

165

T1600 Core Router Hardware Guide

= P

– LL

M greater than zero indicates that the power budget is sufficient to operate the receiver.

Factors that can cause link loss include higher-order mode losses, modal and chromatic dispersion, connectors, splices, and fiber attenuation.

Table 98 on page 166

lists an estimated amount of loss for the factors used in the following sample calculations. For information about the actual amount of signal loss caused by equipment and other factors, refer to vendor documentation.

The following sample calculation for a 2-km-long multimode link with a power budget

) of 13 dB uses the estimated values from

Table 98 on page 166

to calculate link loss

(LL) as the sum of fiber attenuation (2 km @ 1 dB/km, or 2 dB) and loss for five connectors

(0.5 dB per connector, or 2.5 dB) and two splices (0.5 dB per splice, or 1 dB) as well as higher-order mode losses (0.5 dB). The power margin (P

) is calculated as follows:

= P

– LL

= 13 dB – 2 km (1 dB/km) – 5 (0.5 dB) – 2 (0.5 dB) – 0.5 dB

= 13 dB – 2 dB – 2.5 dB – 1 dB – 0.5 dB

= 7 dB

The following sample calculation for an 8-km-long single-mode link with a power budget

) of 13 dB uses the estimated values from

Table 98 on page 166

to calculate link loss

(LL) as the sum of fiber attenuation (8 km @ 0.5 dB/km, or 4 dB) and loss for seven connectors (0.5 dB per connector, or 3.5 dB). The power margin (P

M follows:

) is calculated as

= P

– LL

Chapter 12: Network Cable and Transceiver Specifications

= 13 dB – 8 km (0.5 dB/km) – 7(0.5 dB)

= 13 dB – 4 dB – 3.5 dB

= 5.5 dB

In both examples, the calculated power margin is greater than zero, indicating that the link has sufficient power for transmission and does not exceed the maximum receiver input power.

Installing the T1600 Mounting Hardware for an Open-Frame Rack

In an open-frame rack, center-mounting is generally preferable to front-mounting because the more even distribution of weight provides greater stability. If you center-mount the chassis, you use the center-mounting brackets attached to the chassis. If you front-mount the chassis, you use the front-mounting flanges, and must remove the center-mounting brackets.

Mounting the T1600 Chassis Using a Mechanical Lift

Because of the router's size and weight—up to 606 lb (275 kg) depending on configuration—we strongly recommend that you install the router using a lift.

To mount the chassis in the rack or cabinet using a lift (see

Figure 71 on page 200

If you are installing the router in an open-frame rack, ensure that the rack is in its permanent location and is secured to the building. Ensure that the installation site allows adequate clearance for both airflow and maintenance. For details, see

“Clearance Requirements for Airflow and T1600 Hardware Maintenance” on page 143 .

Load the router onto the lift, making sure it rests securely on the lift platform.

CAUTION: Do not lift the router using the installation handle or the handles on the sides of the chassis. Use these handles only to help position the router.

Using the lift, position the chassis in front of the rack or cabinet, centering it in front of the mounting shelves.

Chapter 18: Installing the T1600 Router into a Rack Using a Mechanical Lift

Lift the chassis approximately 0.75 in. above the surface of the mounting shelves and position it as close as possible to the shelves.

Carefully slide the chassis onto the mounting shelves so that the bottom of the chassis and the mounting shelves overlap by approximately 2 inches.

With one person pulling on the installation handle from the rear of the rack or cabinet while two people push on the front-mounting flanges, slide the chassis onto the mounting shelves until the mounting brackets or front-mounting flanges contact the rack rails or spacer bars (depending on your type of installation). The shelves ensure that the holes in the mounting brackets and the front-mounting flanges of the chassis align with the holes in the rack rails.

Move the lift away from the rack.

If you are installing the router in a four-post rack or cabinet, install a mounting screw and a cage nut into each of the holes aligned with the threaded holes in the spacer bars. If you are installing the router in an open-frame rack, install a mounting screw into each of the open mounting holes aligned with the rack, starting from the bottom.

Visually inspect the alignment of the router. If the router is installed properly in the rack, all the mounting screws on one side of the rack should be aligned with the mounting screws on the opposite side and the router should be level.

T1600 Core Router Hardware Guide

Connecting PIC Cables to the T1600 Router

The router supports PICs that use various kinds of network cable, including multimode and single-mode fiber-optic cable. For information about the type of cable used by each

PIC, see the interface module reference for your device.

You connect PICs to the network by plugging in network cable. To connect cable to the

PICs (see

Figure 105 on page 243 , which shows a fiber-optic PIC):

Have ready a length of the type of cable used by the PIC. For cable specifications, see

Determining Transceiver Support and Specifications for M Series and T Series Routers in the interface module reference for your device.

If the PIC cable connector port is covered by a rubber safety plug, remove the plug.

WARNING: Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cable connected to a transceiver emit laser light that can damage your eyes.

CAUTION: Do not leave a fiber-optic transceiver uncovered except when inserting or removing cable. The safety cap keeps the port clean and prevents accidental exposure to laser light.

Insert the cable connector into the cable connector port on the PIC faceplate.

Arrange the cable in the cable management system to prevent it from dislodging or developing stress points. Secure the cable so that it is not supporting its own weight as it hangs to the floor. Place excess cable out of the way in a neatly coiled loop in the cable management system. Placing fasteners on the loop helps to maintain its shape.

CAUTION: Avoid bending fiber-optic cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.

CAUTION: Do not let fiber-optic cable hang free from the connector. Do not allow fastened loops of cable to dangle, which stresses the cable at the fastening point.

Initially Configuring the T1600 Router

The T1600 Core Router is shipped with Junos OS preinstalled and ready to be configured when the T1600 router is powered on. These procedures connect a router to the network but do not enable it to forward traffic. For complete information about enabling the router to forward traffic, including examples, see the Junos OS configuration guides.

You configure the router by issuing Junos OS command-line interface (CLI) commands, either on a console device attached to the CONSOLE port on the CIP, or over a telnet connection to a network connected to the ETHERNET port on the CIP.

NOTE: These procedures enable you to use the ETHERNET management port. For the initial configuration, use a device attached to the CONSOLE port on the CIP.

For more information about the commands in this procedure see the Junos OS

Administration Library .

Committing the Configuration

For a chassis with two Routing Engines, commit the configuration changes to both Routing

Engines. When you issue the commit synchronize command, the configuration is shared between both Routing Engines and committed on both Routing Engines simultaneously.

For a chassis with only one Routing Engine, use the commit command instead of the commit synchronize command.

Display the configuration to verify that it is correct.

Tools and Parts Required for Replacing T1600 Hardware Components on page 310

T1600 Field-Replaceable Units

Field-replaceable units (FRUs) are router components that can be replaced at the customer site. Replacing most FRUs requires minimal router downtime. The router uses the following types of FRUs:

• Hot-removable and hot-insertable FRUs—You can remove and replace these components without powering off the router or disrupting the routing functions.

• Hot-pluggable FRUs—You can remove and replace these components without powering down the router, but the routing functions of the system are interrupted when the component is removed.

NOTE: Before you replace most host subsystem components, such as a control board or Routing Engine, you must take the host subsystem offline.

However, it is not necessary to halt the host subsystem to insert or remove a PC card.

You must power off the Routing Engine before replacing a CompactFlash card or solid-state disk in a Routing Engine.

Table 106 on page 310

lists the FRUs for the router.

Taking the T1600 Host Subsystem Offline

Before you replace a control board or a Routing Engine, you must take the host subsystem offline. The host subsystem is taken offline and brought online as a unit. Normally, if two host subsystems are installed in the router, RE0 functions as the master and RE1 functions as the backup.

Table 108 on page 365

explains the effect of taking the host subsystem offline.

Table 108: Effect of Taking the Host Subsystem Offline

Type of Host

Subsystem Effect of taking the Host Subsystem Offline

Nonredundant host subsystem

The router shuts down.

Backup host subsystem

The functioning of the router is not interrupted. The backup host subsystem is hot-removable and hot-insertable.

365

T1600 Core Router Hardware Guide

Table 108: Effect of Taking the Host Subsystem Offline (continued)

Type of Host

Subsystem Effect of taking the Host Subsystem Offline

Master host subsystem

The backup host subsystem becomes the master. The backup Routing

Engine assumes Routing Engine functions. The master host subsystem is hot-pluggable. Removal or failure of the master Routing Engine affects forwarding and routing based on the high availability configuration:

• Dual Routing Engines without any high availability features enabled—Traffic is interrupted while the Packet Forwarding Engine is reinitialized. All kernel and forwarding processes are restarted. When the switchover to the new master Routing Engine is complete, routing convergence takes place and traffic is resumed.

•

Graceful Routing Engine switchover (GRES) is enabled—Graceful

Routing Engine switchover preserves interface and kernel information.

Traffic is not interrupted. However, graceful Routing Engine switchover does not preserve the control plane. Neighboring routers detect that the router has restarted and react to the event in a manner prescribed by individual routing protocol specifications. To preserve routing without interruption during a switchover, graceful Routing Engine switchover must be combined with nonstop active routing.

Nonstop active routing is enabled (graceful Routing Engine switchover must be configured for nonstop active routing to be enabled)—Nonstop active routing supports Routing Engine switchover without alerting peer nodes that a change has occurred. Nonstop active routing uses the same infrastructure as graceful Routing Engine switchover to preserve interface and kernel information. However, nonstop active routing also preserves routing information and protocol sessions by running the routing protocol process (rpd) on both Routing Engines. In addition, nonstop active routing preserves TCP connections maintained in the kernel.

•

Nonstop active routing is supported on Junos OS Release 8.5 and later for standalone T1600 routers, Junos OS Release 10.0 and later for T1600 routers in a routing matrix.

Graceful restart is configured—Graceful restart provides extensions to routing protocols so that neighboring helper routers restore routing information to a restarting router. These extensions signal neighboring routers about the graceful restart and prevent the neighbors from reacting to the router restart and from propagating the change in state to the network during the graceful restart period. Neighbors provide the routing information that enables the restarting router to stop and restart routing protocols without causing network reconvergence. Neighbors are required to support graceful restart. The routing protocol process

(rpd) restarts. A graceful restart interval is required. For certain protocols, a significant change in the network can cause graceful restart to stop.

NOTE: Router performance might change if the backup Routing Engine's configuration differs from the former master's configuration. For the most predictable performance, configure the two Routing Engines identically, except for parameters unique to each Routing Engine.

Chapter 28: Replacing Host Subsystem Components

NOTE: For information about configuring graceful Routing Engine switchover

(GRES) and nonstop active routing, see the Junos OS High Availability Library

for Routing Devices.

To take a host subsystem offline:

Determine whether the host subsystem is functioning as the master or as the backup, using one of the two following methods:

• Check the Routing Engine LEDs on the craft interface. If the green MASTER LED is lit, the corresponding host subsystem is functioning as the master.

• Issue the following CLI command. The master Routing Engine is designated Master in the Current state field: user@host> show chassis routing-engine

Routing Engine status:

Slot 0:

Current state Master

...

If the host subsystem is functioning as the master, switch it to backup using the CLI command: user@host> request chassis routing-engine master switch

Halt the Routing Engine.

user@host> request system halt

Wait until a message appears on the console confirming that the operating system has halted.

The command shuts down the Routing Engine cleanly, so its state information is preserved.

NOTE: The SIBs might continue forwarding traffic for approximately 5 minutes after the request system halt command has been issued.

On the console or other management device connected to the other Routing Engine, enter CLI operational mode and issue the following command.

user@host> request chassis cb offline slot n n is 0 or 1 for the slot number of the host subsystem being taken offline.

Verify that the control board is offline:

If the router is powered on and the Routing Engine's corresponding control board is functioning normally, the Routing Engine comes online automatically. To verify that the

Routing Engine is functioning normally:

Check the HOST0 and HOST1 LEDs on the craft interface.

• The green OK LED should light steadily a few minutes after the Routing Engine is installed.

• If the red FAIL LED is lit steadily, remove and install the Routing Engine again (see

“Removing a T1600 Routing Engine” on page 374

and

“Installing the T1600 Routing

Engine” on page 376

). Make sure that the Routing Engine is seated properly. If the

FAIL LED still lights steadily, the Routing Engine is not functioning properly. Contact your customer support representative.

Verify that the Routing Engine is functioning properly. Display the status of the Routing

Engine by issuing the show chassis routing-engine command: user@host> show chassis routing-engine

Removing a T1600 FPC on page 395

Replacing a T1600 FPC

The FPCs are hot-insertable and hot-removable. When you remove an FPC, the router continues to function, although the PIC interfaces installed on the FPC being removed no longer function.

Installing a T1600 FPC on page 398

Removing a T1600 FPC

The router holds up to eight FPCs, which are installed vertically in the front of the router.

An empty FPC weighs approximately 25 lb (11.3 kg) and an FPC with PICs installed can weigh up to 37 lb (14.5 kg).

Each FPC slot not occupied by an FPC must be covered by an FPC blank panel. An FPC blank panel weighs 7 lb (3 kg).

To remove an FPC (see

Figure 185 on page 397 ):

Place an electrostatic bag or antistatic mat on a flat, stable surface.

Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.

Use one of the following methods to take the FPC offline:

• Press and hold the FPC online/offline button. The green OK LED next to the button begins to blink. Hold the button down until the LED goes out. The LEDs and online/offline button for each FPC are located directly above it on the craft interface.

• Issue the following CLI command: user@host> request chassis fpc slot slot-number offline

395

T1600 Core Router Hardware Guide

For more information about the command, see request chassis fpc .

Disconnect the cables from the PICs installed in the FPC. If a PIC uses fiber-optic cable, immediately cover each transceiver and the end of each cable with a rubber safety cap. Arrange the disconnected cables in the cable management system, to prevent the cables from developing stress points.

CAUTION: Do not leave a fiber-optic transceiver uncovered except when inserting or removing cable. The safety cap keeps the port clean and prevents accidental exposure to laser light.

CAUTION: Avoid bending fiber-optic cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.

After you remove each PIC, immediately place it on an antistatic mat or in an electrostatic bag.

If you are removing a Type 2 FPC or Type 3 FPC, loosen the screws inside the ejector handles at the top and bottom of the FPC faceplate.

Simultaneously turn both the ejector handles counterclockwise to unseat the FPC.

Grasp the handles and slide the FPC straight out of the card cage halfway.

CAUTION: The weight of the FPC is concentrated in the back end. Be prepared to accept the full weight—up to 37 lb (14.5 kg)—as you slide the

FPC out of the chassis.

When the FPC is out of the chassis, do not hold it by the ejector handles, bus bars, or edge connectors. They cannot support its weight.

Chapter 29: Replacing Line Card Components

Do not stack FPCs on top of one another after removal. Place each one individually in an electrostatic bag or on its own antistatic mat on a flat, stable surface.

10.

If you are not reinstalling an FPC into the emptied FPC slot within a short time, install a blank FPC panel over the slot to maintain proper airflow in the FPC card cage.

CAUTION: After removing an FPC from the chassis, wait at least 30 seconds before reinserting it, removing an FPC from a different slot, or inserting an FPC into a different slot.

Take each PIC to be installed in the replacement FPC out of its electrostatic bag and identify the slot on the FPC where it will be connected.

Verify that each fiber-optic PIC has a rubber safety cap covering the PIC transceiver.

If it does not, cover the transceiver with a safety cap.

Install each PIC into the appropriate slot on the FPC. For information about installing a PIC, see

“Installing a T1600 PIC” on page 405 .

Locate the slot in the FPC card cage in which you plan to install the FPC.

Inspect the slot in the FPC card cage to verify that there are no missing or bent pins on the midplane.

Inspect the FPC to verify that the connectors are not misaligned or damaged.

Orient the FPC vertically with the component side facing to the right. Be sure the FPC is right-side up, with the components on the right of the FPC.

CAUTION: When the FPC is out of the chassis, do not hold it by the ejector handles, bus bars, or edge connectors. They cannot support its weight.

Chapter 29: Replacing Line Card Components

Removing a T1600 PIC

PICs are hot-insertable and hot-removable. When you remove a PIC, the router continues to function, although the PIC interfaces being removed no longer function.

The PICs are located in the FPCs installed in the front of the router. A PIC weighs less than 2 lb (0.9 kg).

To remove a PIC (see

Figure 189 on page 405

Place an electrostatic bag or antistatic mat on a flat, stable surface to receive the

PIC. If the PIC connects to fiber-optic cable, have ready a rubber safety cap for each transceiver and cable.

Attach an electrostatic discharge ESD grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.

Use one of the following methods to take the PIC offline:

• Press and hold the online/offline button until the PIC LED goes out (about 5 seconds).

For a PIC installed in a Type 1 FPC, use a tool—such as a flat-blade screwdriver—to press the button slightly beneath the faceplate of the PIC. For a PIC installed in a

Type 2 FPC or Type 3 FPC, use a narrow-ended tool that fits inside the opening that leads to the button.

• Issue the following CLI command: user@host> request chassis pic fpc-slot fpc-slot pic-slot pic-slot offline

For more information about the command, see request chassis pic .

Label the cables connected to the PIC so that you can later reconnect each cable to the correct PIC.

Disconnect the cables from the PIC. If the PIC uses fiber-optic cable, immediately cover each transceiver and the end of each cable with a rubber safety cap.

CAUTION: Do not leave a fiber-optic transceiver uncovered except when inserting or removing cable. The safety cap keeps the port clean and prevents accidental exposure to laser light.

403

T1600 Core Router Hardware Guide

CAUTION: Avoid bending fiber-optic cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.

Unseat the PIC:

• Type 1 or Type 2 PIC—Loosen the captive screws at the top and bottom of the PIC faceplate.

• Type 3 PIC—Loosen the captive screw at the bottom of the PIC faceplate, then twist the ejector handle at the top of the faceplate and counterclockwise to unseat the

PIC.

• Type 4 PIC—Twist the ejector handle at the bottom of the PIC faceplate, then twist the ejector handle at the top of the faceplate and counterclockwise to unseat the

PIC.

Slide the PIC out of the FPC card carrier, and place it in the electrostatic bag or on the antistatic mat.

If you are not reinstalling a PIC into the emptied PIC slot within a short time, install a blank PIC panel over the slot to maintain proper airflow in the FPC card cage.

•

Installing a T1600 PIC

To install a PIC (see

Figure 190 on page 407

Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.

If the PIC uses fiber-optic cable, verify that there is a rubber safety cap over each transceiver on the faceplate. Install a cap if necessary.

Align the notches in the connector at the rear of the PIC with the notches in the PIC slot in the FPC and then slide the PIC in until it lodges firmly in the FPC.

CAUTION: Slide the PIC straight into the slot to avoid damaging the components on the bottom of the PIC.

405

T1600 Core Router Hardware Guide

Secure the PIC to the FPC faceplate:

• Type 1 or Type 2 PICs—Tighten the captive screws at the top and bottom of the faceplate.

• Type 3 PICs—Turn the ejector handle at the top of the PIC faceplate clockwise, then tighten the captive screw at the bottom of the faceplate.

• Type 4 PIC—Twist the ejector handle at the bottom of the PIC faceplate, then twist the ejector handle at the top of the faceplate and counterclockwise to unseat the

PIC.

If the PIC uses fiber-optic cable, remove the rubber safety cap from each transceiver and the end of each cable.

CAUTION: Do not leave a fiber-optic transceiver uncovered except when inserting or removing cable. The safety cap keeps the port clean and prevents accidental exposure to laser light.

Insert the appropriate cables into the cable connectors on the PIC.

Arrange each cable in the cable management system to prevent the cable from dislodging or developing stress points. Secure the cable so that it is not supporting its own weight as it hangs to the floor. Place excess cable out of the way in a neatly coiled loop in the cable management system. Placing fasteners on the loop helps to maintain its shape.

CAUTION: Do not let fiber-optic cable hang free from the connector. Do not allow fastened loops of cable to dangle, which stresses the cable at the fastening point.

CAUTION: Avoid bending fiber-optic cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.

Use one of the following methods to bring the PIC online:

• Press the PIC offline/online button until the PIC LED lights green. For a PIC installed in a Type 1 FPC, use a tool—such as a flat-blade screwdriver—to press the button

Chapter 29: Replacing Line Card Components slightly beneath the faceplate of the PIC. For a PIC installed in a Type 2 FPC or Type

3 FPC, use a narrow-ended tool that fits inside the opening that leads to the button.

When a redundant power supply is powered down, the other power supply automatically assumes the entire electrical load for the router.

If you have only one power supply, you must power off the system before removing the

AC power supply cord.

Replacing a T1600 TXP-LCC-3D SIB

Five SIBs are located in the rear of the chassis in the slots marked SIB0 through SIB4 .

The TXP-LCC-3D SIBs connect to the TXP-F13-3D SIBs in a TX Matrix Plus router.

TXP-LCC-3D SIBs in active data switching planes are hot-pluggable. TXP-LCC-3D SIBs in a spare data switching planes are hot-insertable and hot-removable. When you remove a TXP-LCC-3D SIB in a spare switching plane, traffic forwarding continues without any degradation as long as the other four switching planes remain online. However, removing a TXP-LCC-3D SIB in an active switching plane might cause performance degradation in that switching plane. To avoid performance degradation, you can take the switching plane offline before you remove a TXP-LCC-3D SIB. For more information, see the TX

493

T1600 Core Router Hardware Guide

Removing a T1600 SFP

Small form-factor pluggables (SFPs) are transceivers that can be removed from a PIC.

SFPs are hot-insertable and hot-removable. Removing an SFP does not interrupt PIC functioning, but the removed SFP no longer receives or transmits data.

NOTE: When you remove a PIC transceiver, the router continues to function, although the PIC interface being removed no longer functions.

Figure 250: Small Form-Factor Pluggable (SFP)

Connector

Locking pin

NOTE: This procedure applies to both SFP and SFP+ transceivers.

To remove an SFP transceiver (see

Figure 250 on page 494 ):

Place an electrostatic bag or antistatic mat on a flat, stable surface to receive the

SFP. Have ready a rubber safety cap for the SFP transceiver and the cable.

Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.

Label the cable connected to the SFP so that you can later reconnect it to the correct

SFP.

Disconnect the cable from the SFP. Immediately cover the transceiver and the end of the cable with a rubber safety cap.

CAUTION: Do not leave a fiber-optic transceiver uncovered except when inserting or removing cable. The safety cap keeps the port clean and prevents accidental exposure to laser light.

Chapter 31: Replacing Switch Fabric Components

CAUTION: Avoid bending fiber-optic cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.

Pull the ejector handle away from the SFP faceplate to unseat the SFP from the PIC.

Pull the SFP out of the PIC, and place it on the antistatic mat or in the electrostatic bag.

CAUTION: After removing a transceiver from the chassis, wait at least 30 seconds before reinserting it or inserting a transceiver into a different slot.

Installing a T1600 SFP

To install a replacement SFP:

Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.

Verify that a rubber safety cap covers the SFP transceiver, installing one if necessary.

Orient the SFP over the port in the PIC so that the connector end will enter the slot first and the SFP connector faces the appropriate direction:

• If the PIC has ten SFP ports, the ports are arranged in two columns. The SFP connector faces to the right for ports in the left column, and to the left for ports in the right column.

• If the PIC has one or two SFP ports, the SFP connector faces to the left.

Slide the SFP into the slot. If there is resistance, remove the SFP and flip it so that the connector faces the other direction.

495

T1600 Core Router Hardware Guide

496

Remove the rubber safety cap from the transceiver and the end of the cable, and insert the cable into the transceiver.

CAUTION: Do not leave a fiber-optic transceiver uncovered except when inserting or removing cable. The safety cap keeps the port clean and prevents accidental exposure to laser light.

Arrange the cable in the cable management system to prevent the cable from dislodging or developing stress points. Secure the cable so that it is not supporting its own weight as it hangs to the floor. Place excess cable out of the way in a neatly coiled loop in the cable management system. Placing fasteners on the loop helps to maintain its shape.

CAUTION: Do not let fiber-optic cable hang free from the connector. Do not allow fastened loops of cable to dangle, which stresses the cable at the fastening point.

CAUTION: Avoid bending fiber-optic cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.

Verify that the status LEDs on the PIC faceplate indicate that the SFP is functioning correctly (there is an LED for each SFP port). For more information about the PIC

LEDs, see the interface module reference for your device. You can also verify PIC functioning by issuing the show chassis fpc pic-status command.

Maintaining the T1600 Air Filters

Purpose For optimum cooling, verify the condition of the air filters.

Air filters for both the front and rear fan trays help keep dust and other particles from entering the cooling system. To function properly, the entire cooling system requires an unobstructed airflow and proper clearance around the site, as described in

“Clearance

Figure 253: Airflow Through the Chassis

510

Action Check the air filters regularly for dust and debris. The filter elements degrade over time, so the filter elements in use, must be replaced every 6 months. For procedures to replace the air filters, see

“Replacing the T1600 Rear Air Filter” on page 316

and

“Replacing the

T1600 Front Air Filter” on page 313 .

The shelf life of polyurethane filter varies from two years to five years depending on the storage conditions. Store in a cool, dry, and dark environment. Wrap the media in plastic and store in an environment with relative humidity between 40%- 80% and temperature between 40°F (4° C) to 90°F (32° C). Note that if the material flakes, or becomes brittle when rubbed or deformed, it is no longer usable.

Chapter 33: Maintaining Components

CAUTION: Always keep both air filters in place while the router is operating.

Because the fans are very powerful, they could pull small bits of wire or other materials into the router through the unfiltered air intake. This could damage the router components.

Preventing Damage to FPCs

CAUTION: Many components on the FPC are fragile. Failure to handle FPCs as specified in this document can cause irreparable damage.

CAUTION: To prevent damage when handling or carrying FPCs:

• As you carry the FPC, do not bump it against anything. FPC components are fragile.

• Do not grasp the FPC anywhere except places that this document indicates.

In particular, never grasp the connector edge, especially at the power

515

T1600 Core Router Hardware Guide connector in the corner where the connector and bottom edges meet (see

Figure 254 on page 516

• Do not carry the FPC by the faceplate with only one hand (see

Figure 255 on page 517 ).

• Do not rest any edge of an FPC directly against a hard surface (see

Figure 256 on page 517

). If you must rest the FPC temporarily on an edge while changing its orientation between vertical and horizontal, use your hand as a cushion between the edge and the surface.

Holding T1600 FPCs Vertically

NOTE: An FPC configured with PICs installed can weigh as much as

37 lb (14.5 kg). Be prepared to accept the full weight of the FPC as you lift it.

You hold an FPC vertically when installing it into the chassis. To hold an FPC vertically

(see

Figure 257 on page 518

Orient the FPC so that the faceplate faces you.

Place one hand around the FPC faceplate about a quarter of the way down from the top edge. To avoid deforming the electromagnetic interference (EMI) shielding strip, do not press hard on it.

Place your other hand at the bottom edge of the FPC. If the FPC has heat sinks about midway between the faceplate and connector edge, place your other hand against the heat sinks.

Storing T1600 FPCs

When an FPC is not installed in a router, the FPC must be either stored in the container in which a spare FPC is shipped or stored horizontally with the component-side up on a flat, stable surface. When you store an FPC on a horizontal surface or in the shipping container, always place it inside an antistatic bag. Because the FPC is heavy and because antistatic bags are fragile, inserting the FPC into the bag is easier with two people. The storage procedures are as follows:

• When storing an FPC with two people, one person holds the FPC in the horizontal position with the faceplate facing their body, the other person slides the opening of the bag over the FPC connector edge.

• When storing an FPC with one person, you must insert the FPC into a bag by yourself.

First lay the FPC horizontally on a flat, stable surface, component-side up. Orient the

FPC with the faceplate facing you. Carefully insert the FPC connector edge into the opening of the bag, and pull the bag toward you to cover the FPC.

CAUTION: To prevent damage when storing FPCs:

• Never lay an FPC component-side down.

• Use the cable management system to support cables and prevent cables from dislodging or developing stress points.

• Place excess cable out of the way in the cable management system. Do not allow fastened loops of cable to dangle from the connector or cable management system, because this stresses the cable at the fastening point. Putting fasteners on the loops helps to maintain their shape.

• Keep the cable connections clean and free of dust and other particles, which can cause drops in the received power level. Always inspect cables and clean them if necessary before connecting an interface.

• Label both ends of PIC cables to identify them.

The following guidelines apply specifically to fiber-optic cable:

• When you unplug a fiber-optic cable from a PIC, always place a rubber safety plug over the transceiver on the PIC faceplate and on the end of the cable.

• Anchor fiber-optic cable to avoid stress on the connectors. When attaching fiber to a

PIC, be sure to secure the fiber so it is not supporting its own weight as it hangs to the floor. Never let fiber-optic cable hang free from the connector.

• Avoid bending fiber-optic cable beyond its bend radius. An arc smaller than a few inches can damage the cable and cause problems that are difficult to diagnose.

• Frequent plugging and unplugging of fiber-optic cable into and out of optical instruments, such as ATM or SONET/SDH analyzers, can cause damage to the instruments that is expensive to repair. Instead, attach a short fiber extension to the optical equipment. Any wear and tear due to frequent plugging and unplugging is then absorbed by the short fiber extension, which is easy and inexpensive to replace.

• Keep fiber-optic cable connections clean. Small microdeposits of oil and dust in the canal of the transceiver or cable connector could cause loss of light, reducing signal power and possibly causing intermittent problems with the optical connection.

To clean the transceivers, use an appropriate fiber-cleaning device, such as RIFOCS

Fiber Optic Adaptor Cleaning Wands (part number 946). Follow the directions for the cleaning kit you use.

After you have cleaned the transceiver on the fiber-optic PIC, make sure that the connector tip of the fiber-optic cable is clean. Use only an approved alcohol-free fiber-optic cable cleaning kit, such as the Opptex Cletop-S

Fiber Cleaner. Follow the directions for the cleaning kit you use.

Maintaining the T1600 Power Supplies

Purpose For optimum router performance, verify the condition of the power supplies.

Action On a regular basis:

• Make sure that the power and grounding cables are arranged so that they do not obstruct access to other router components.

• The power supplies require an unobstructed airflow at both the front and rear of the chassis. Periodically check the site to ensure that both the air intake at the bottom front of the chassis and the exhaust from the power supply faceplates are unobstructed.

• Periodically inspect the site to ensure that the grounding and power cables connected to the router are securely in place and that no moisture accumulating near the router.

To review grounding and site wiring requirements for the router, see

“T1600 Chassis

and

“Site Electrical Wiring

Guidelines for Juniper Networks Devices” on page 622 .

• Regularly inspect the air filters on each power supply for dust and debris, and replace the side filter on AC power supplies or front filter element on AC and DC power supplies every 6 months.

To replace a power supply air filter element, see the following topics:

• Routinely check the LEDs on the DC power supply faceplates.

During normal operation:

• For DC power supplies, the blue DC OK LEDs light to indicate that the power supplies are functioning normally.

• For DC power supplies, each green INPUT PRESENT LED on a DC power supply lights when the input is receiving source DC power.

• For three-input 240 -A power supplies and four-input 240 -A DC power supplies, each CB ON LED on a DC power supply lights when the circuit breaker is on.

525

T1600 Core Router Hardware Guide

• Routinely check the LEDs on the AC power supply faceplates. If the AC OK LEDs are lit, the AC terminal blocks are receiving power. If the DC OK LEDs are lit, the AC power supplies are functioning normally.

• Check the red and yellow alarm LEDs and the LCD on the craft interface. Power supply failure or removal triggers an alarm that causes one or both of the LEDs to light and an error message to appear on the LCD. You can display the associated error messages by issuing the following CLI command: user@host> show chassis alarms

If 0 is displayed for the SCG/CB/SIB in the Current, Power, and Load fields for a PEM, and the voltage field does not match the other PEM, it might indicate a difference between the DC input voltages applied to PEM0 and PEM1 . Consider checking your

DC power network for unintended voltage drops to the router (see

Figure 59 on page 151

for a typical DC source cabling arrangement).

The current sharing between DC power supplies relies on equal voltages at the input terminals of the power supplies. However, if the voltages do not match, the router operates normally as long as the DC input voltages are within the operating range provided in

Table 85 on page 145 .

• For the three-input 240-A DC power supplies, system power is divided into two load zones. One load zone consists of INPUT 0 of PEM0 and PEM1 . The other load zones consist of INPUT 1 and INPUT 2 of PEM0 and PEM1 . Load sharing occurs between the two power supplies for each load zone. Therefore, the input voltage for the inputs in each load zone must be equal in both power supplies for current sharing. For example, the input voltage for INPUT 0 of PEM0 and the input voltage for INPUT 0 of PEM1 must be the same for current sharing to occur within that load zone.

• For the four-input 240-A DC power supplies, system power is divided into four load zones. One load zone consists of INPUT 0 of PEM0 and PEM1 . The other load zones consist of INPUT 1 , INPUT 2 and INPUT 3 of PEM0 and PEM1 . Load sharing occurs between the two power supplies for each load zone. Therefore, the input voltage for the inputs in each load zone must be equal in both power supplies for current sharing. For example, the input voltage for INPUT 0 of PEM0 and the input voltage for INPUT 0 of PEM1 must be the same for current sharing to occur within that load zone.

As part of your routine maintenance, we recommend that you clean all exposed fiber-optic array components each time you disconnect and reconnect a fiber-optic array cable, or if the optical link is not functioning correctly.

NOTE: While you install the router or replace a fiber-optic array cable, small deposits of oil, dust, and debris can enter the fiber-optic array ports, the fiber-optic array cable connectors, and the loopback connectors and adapters used to test the optical connections. These deposits can cause loss of light, reducing signal power and causing intermittent problems with the optical connection.

The following tools for cleaning the fiber-optic components are provided in the TX Matrix

Plus tool kit:

• Dry cleaning tool (see

Figure 260 on page 532 ). This tool uses a dry cloth to remove

dust and oil from the fiber optics.

• Cleaning tool adapter

• Cleaning tool connector

T1600 Troubleshooting Resources

To troubleshoot a T1600 router, you use the Junos OS command-line interface (CLI),

LCD, alarms, devices connected to the alarm relay contacts on the CIP, and LEDs on both the components and craft interface.

• LEDs—When the Routing Engine detects an alarm condition, it lights the red or yellow alarm LED on the craft interface as appropriate. In addition, you can also use the component-specific LEDs on the craft interface and on the faceplate of a component to troubleshoot the routing matrix.

• LCD—When a red or yellow alarm occurs, the cause of the alarm messages is displayed on the craft interface LCD. Use the CLI to display more information about the alarm.

• Alarm devices connected to the alarm relay contact on the CIP—When a red or yellow alarm occurs, it trips the corresponding alarm relay contact on the CIP.

539

T1600 Core Router Hardware Guide

• CLI—The CLI is the primary tool for controlling and troubleshooting hardware, Junos

OS, routing protocols, and network connectivity. CLI commands display information from routing tables, information specific to routing protocols, and information about network connectivity derived from the ping and traceroute utilities.

For information about using the CLI to troubleshoot Junos OS, see the appropriate

Junos OS configuration guide.

• JTAC—If you need assistance during troubleshooting, you can contact the Juniper

Networks Technical Assistance Center (JTAC) by using the Web or by telephone. If you encounter software problems, or problems with hardware components not discussed here, contact JTAC.

Check the display on the craft interface to determine the source of a yellow or red alarm (see

Table 115 on page 553

). Junos OS constantly updates the screen with status information for each component.

NOTE: On the display and in the CLI, the power supplies are referred to as PEM0 and PEM0 , from top to bottom.

If the system temperature exceeds the threshold, Junos OS shuts down all power supplies so that no status is displayed.

Junos OS also can shut down one of the power supplies for other reasons.

In that case, the remaining power supply assumes the load, and you can still view the system status through the CLI or display.

Verify that the source circuit breaker has the proper current rating.

NOTE: All inputs on a DC power supply in slot PEM0 must be powered by dedicated power feeds derived from feed A, and all inputs on a DC power supply in slot PEM 1 must be powered by dedicated power feeds derived from feed B. This configuration provides the commonly deployed A/B feed redundancy for the system.

NOTE: The AC power cord on an AC power supply in slot PEM0 must be powered by a dedicated power feed derived from feed A, and The AC power cord on an AC power supply in slot PEM 1 must be powered by dedicated power feeds derived from feed B. This configuration provides the commonly deployed A/B feed redundancy for the system.

Verify that the DC power cables or AC power cord from the power source to the router are not damaged. If the insulation is cracked or broken, immediately replace the DC power cable or AC power cord.

Connect the power supply to a different power source with a new DC power cable or

AC power cord. If the power supply DC OK LED still does not light, the power supply is the source of the problem. Replace the power supply with a spare.

DC OK LED on the installed spare does not light—the replaced power supply might be faulty. To return it for replacement, see

If you cannot determine the cause of the problem or need additional assistance, see

Testing a Fiber-Optic Array Switching Plane Port

Four fiber-optic array loopback connectors are shipped in the tool kit with the TX Matrix

Plus router (see

Figure 264 on page 559

NOTE: Use the loopback connectors to test the TXP-F13 ports.

Figure 264: TX Matrix Plus Fiber-Optic Array Switching Plane Loopback Connector and

Loopback Adapter

Loopback adapter Loopback connector

CAUTION: Do not connect and disconnect the fiber-optic array switching plane cable connectors, loopback connectors, or loopback adapters more frequently than required to perform the procedures in this hardware guide.

These fiber-optic components are rated for a limited number of insertions

(approximately 100).

To use the loopback connectors to test the TXP-F13 SIB fiber-optic array switching plane ports:

Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.

Take the switching plane offline.

See Taking a Switching Data Plane Offline in the TX Matrix Plus Router Hardware Guide .

Bring the TXP-F13 SIB offline by pressing the SFC ONLINE/OFFLINE button.

Remove the dust covers from the loopback connectors and from the fiber-optic array switching plane ports. Temporarily store the dust covers in a dust-free resealable plastic bag.

559

T1600 Core Router Hardware Guide

CAUTION: During maintenance or replacement procedures, small deposits of oil, dust, and debris can enter the TXP-F13 SIB and TXP-T1600 SIB fiber-optic array switching plane ports, the fiber-optic array switching plane cable connectors, and the loopback connectors and adapters.

Align a loopback connector with each TXP-F13 SIB fiber-optic array switching plane port, and carefully press it into the port until it stops. The loopback connector and fiber-optic array switching plane port are keyed to ensure proper mating.

Bring the TXP-F13 SIB online by pressing the SFC ONLINE/OFFLINE button.

Verify that the RxPWR LED for that fiber-optic array switching plane port is steadily lit green.

If the RxPWR LED for any fiber-optic array switching plane port is lit steadily yellow or is not lit , take the TXP-F13 SIB offline again, remove the loopback connector, and clean the fiber-optic array switching plane ports and loopback connectors. Then reconnect the loopback connectors.

If the RxPWR LEDs for the fiber-optic array switching plane ports still fail to light steadily green, contact your customer support representative for additional instructions.

After you have finished testing the fiber-optic array switching plane port, remove a dust cover from the dust-free resealable plastic bag. To reinstall the dust cover on the loopback connector, align the dust cover with the loopback connector, and carefully press them together until they stop. The covers and the loopback connectors are keyed to ensure proper mating. Store the loopback connectors in the dust-free resealable plastic bag.

Take the switching plane offline.

See Taking a Switching Data Plane Offline in the TX Matrix Plus Router Hardware Guide .

Bring the TXP-F13 SIB offline by pressing the ONLINE/OFFLINE button for the SFC.

WARNING: Do not look directly into a fiber-optic array switching plane port or a connector at the end of a fiber-optic array switching plane cable connected to a port. The optics emit laser light that can damage your eyes.

Disconnect the fiber-optic array switching plane cable from the port.

Install a dust cover on the fiber-optic array switching plane port.

Clean the fiber-optic array switching plane cable and loopback adapter.

CAUTION: During maintenance or replacement procedures, small deposits of oil, dust, and debris can enter the TXP-F13 SIB and TXP-T1600 SIB fiber-optic array switching plane ports, fiber-optic array switching plane cable connectors, and loopback connectors and adapters. We recommend that you clean the optics in these components immediately before connecting them.

Align the loopback adapter with the cable connector, and carefully press it into the connector until it stops. The loopback adapter and the cable connector are keyed to ensure proper mating.

Bring the TXP-F13 SIB online by pressing the ONLINE/OFFLINE button for the SFC.

T1600 Core Router Hardware Guide

WARNING: Do not look directly into a fiber-optic array switching plane port or a connector at the end of a fiber-optic array switching plane cable connected to a port. The fiber optics emit laser light that can damage your eyes.

10.

Verify that the RxPWR LED for the fiber-optic array switching plane port is steadily lit green.

11.

If the RxPWR LED for a fiber-optic array switching plane port is lit steadily yellow or is not lit, bring the TXP-F13 SIB offline, remove the loopback adapter, and clean it and the fiber-optic array cable. After you have cleaned the fiber-optic array switching plane cable and the loopback adapter, repeat the procedure. If the RxPWR LED for a fiber-optic array switching plane port still does not steadily light green, contact your customer support representative for additional instructions. Do not proceed with the installation of the TX Matrix Plus router until you have spoken to your customer support representative.

12.

Remove a dust cover from the dust-free resealable plastic bag and reinstall it on the loopback adapter. Align the dust cover with the loopback adapter, and carefully press them together until they stop. The cover and the loopback adapter are keyed to ensure proper mating. Store the loopback adapter in the dust-free resealable plastic bag.

Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.

On the console or other management device connected to the master Routing Engine, enter CLI operational mode. To shut down the router software: user@host> request system halt

(If two Routing Engines are installed, also issue the command on the backup Routing

Engine.) Wait until a message appears on the console confirming that the operating system has halted.

The command shuts down the Routing Engine cleanly, so its state information is preserved. For more information about the command, see request system halt .

NOTE: The SIB might continue forwarding traffic for approximately 5 minutes after the request system halt command has been issued.

For all power supplies, shut down power to the router by pressing the circuit breakers to the off ( O ) position, or the power switch to the standby position.

T1600 Preventing Electrostatic Discharge Damage

Many router hardware components are sensitive to damage from static electricity. Some components can be impaired by voltages as low as 30 V. You can easily generate potentially damaging static voltages whenever you handle plastic or foam packing material or if you move components across plastic or carpets. Observe the following guidelines to minimize the potential for electrostatic discharge (ESD) damage, which can cause intermittent or complete component failures:

• Always use an ESD wrist strap or ankle strap, and make sure that it is in direct contact with your skin.

CAUTION: For safety, periodically check the resistance value of the ESD strap. The measurement should be in the range of 1 to 10 Mohms.

• When handling any component that has been removed from the chassis, verify that the equipment end of your ESD strap is attached to one of the ESD points on the chassis, which are shown in

Figure 279 on page 589

and

Figure 280 on page 590 .

• Avoid contact between the component and your clothing. ESD voltages emitted from clothing can still damage components.

• When removing or installing a component, always place it component-side up on an antistatic surface, in an antistatic card rack, or in an electrostatic bag (see

Figure 281 on page 590 ). If you are returning a component, place it in an electrostatic

bag before packing it.

Fire Suppression Equipment on page 593

General Fire Safety Requirements

In the event of a fire emergency involving network devices, the safety of people is the primary concern. Establish procedures for protecting people in a fire emergency, provide safety training, and properly provision fire-control equipment and fire extinguishers.

In addition, establish procedures to protect your equipment in a fire emergency. Juniper

Networks products must be installed in an environment suitable for electronic equipment.

We recommend that fire suppression equipment be available in the event of a fire in the vicinity of the equipment, and that you observe all local fire, safety, and electrical codes and ordinances when installing and operating your equipment.

Fire Suppression

In the event of an electrical hazard or an electrical fire, first turn off power to the equipment at the source. Then use a Type C fire extinguisher, which uses noncorrosive fire retardants, to extinguish the fire.

Fire Suppression Equipment

Type C fire extinguishers, which use noncorrosive fire retardants such as carbon dioxide

(CO

) and Halotron, are most effective for suppressing electrical fires. Type C fire extinguishers displace the oxygen from the point of combustion to eliminate the fire. For extinguishing fire on or around equipment that draws air from the environment for cooling, use this type of inert oxygen displacement extinguisher instead of an extinguisher that leave residues on equipment.

Do not use multipurpose Type ABC chemical fire extinguishers (dry chemical fire extinguishers) near Juniper Networks devices. The primary ingredient in these fire extinguishers is monoammonium phosphate, which is very sticky and difficult to clean.

593

T1600 Core Router Hardware Guide

In addition, in minute amounts of moisture, monoammonium phosphate can become highly corrosive and corrodes most metals.

Any equipment in a room in which a chemical fire extinguisher has been discharged is subject to premature failure and unreliable operation. The equipment is considered to be irreparably damaged.

NOTE: To keep warranties effective, do not use a dry chemical fire extinguisher to control a fire at or near a Juniper Networks device. If a dry chemical fire extinguisher is used, the unit is no longer eligible for coverage under a service agreement.

We recommend that you dispose of any irreparably damaged equipment in an environmentally responsible manner.

T1600 Chassis Lifting Guidelines

• Before moving the router, follow the guidelines in the site preparation checklist to verify that the intended site meets the specified power, environmental, and clearance requirements.

• Do not attempt to lift a fully configured router by yourself. Using a mechanical lift to maneuver the router into a rack is recommended. If a lift cannot be used, a minimum of four people is required to lift the router, and you must remove components from the chassis before lifting.

• Before lifting or moving the router, disconnect all external cables.

• As when lifting any heavy object, lift most of the weight with your legs rather than your back. Keep your knees bent and your back relatively straight and avoid twisting your body as you lift. Balance the load evenly and be sure that your footing is solid.

T1600 General Laser Safety Guidelines

Devices with single-mode optical interfaces are equipped with laser transmitters, which are considered Class 1 Laser product by the U.S. Food and Drug Administration, and are evaluated as a Class 1 Laser Product according to EN 60825–1 +A11 +A2 requirements.

When working around devices with optical interfaces, observe the following safety guidelines to prevent eye injury:

• Do not look into unterminated ports or at fibers that connect to unknown sources.

• Do not examine unterminated optical ports with optical instruments.

• Avoid direct exposure to the beam.

WARNING: Unterminated optical connectors can emit invisible laser radiation. The lens in the human eye focuses all the laser power on the retina, so focusing the eye directly on a laser source—even a low-power laser—could permanently damage the eye.

T1600 DC Power Electrical Safety Guidelines

The following electrical safety guidelines apply to a DC-powered router:

• Be sure to connect the ground wire or conduit to a solid office (earth) ground. A closed loop ring is recommended for terminating the ground conductor at the ground stud.

• A DC-powered router is equipped with a DC terminal block that is rated for the power requirements of a maximally configured router.

To supply sufficient power, terminate the DC input wiring on a facility DC source capable of supplying at least 67 A @ –48 VDC per input for the three-input 240-A DC power supply, 48 A @ –48 VDC per input for the four-input 240-A DC power supply, or 56 A

@ –48 VDC per input for the six-input DC power supply.

• Incorporate an easily accessible disconnect device into the facility wiring. In the United

States and Canada, the –48 VDC facility should be equipped with a circuit breaker rated a minimum of 125% of the power provisioned for the input in accordance with the National Electrical Code in the US and the Canadian Electrical Code in Canada.

WARNING: For the six-input DC power supply, failure to provide the required circuit breaker or current-limiting fuse for each DC power cable can cause injury or damage to equipment.

For the six-input DC power supply, each 48 VDC facility DC source input power cable must be equipped with a current-limiting fuse or circuit breaker external to the Juniper

Networks equipment rated at 80 A (–48 VDC) maximum. The voltage rating of the facility DC source circuit breaker must be 80 V minimum. We recommend an 80 A circuit breaker or current-limiting fuse rated for each 60 A DC power cable.

We recommend that the 48 VDC facility DC source be equipped with a circuit breaker rated at 80 A (–48 VDC) minimum for the three-input 240-A DC power supply or

60 A (–48 VDC) minimum for the four-input 240-A power supply, or as required by local code.

• Run two wires from the circuit breaker box to a source of 48 VDC. Use appropriate gauge wire to handle up to 80 A for a three-input 240-A DC power supply or 60 A for a four-input 240-A power supply.

• A DC-powered router that is equipped with a DC terminal block is intended only for installation in a restricted access location. In the United States, a restricted access area is one in accordance with Articles 110-16, 110-17, and 110-18 of the National Electrical

Code ANSI/NFPA 70.

NOTE: Primary overcurrent protection is provided by the building circuit breaker. This breaker should protect against excess currents, short circuits, and earth faults in accordance with NEC ANSI/NFPA70.

Chapter 43: Electrical Safety Guidelines and Warnings

• Ensure that the polarity of the DC input wiring is correct. Under certain conditions, connections with reversed polarity might trip the primary circuit breaker or damage the equipment.

• For personal safety, connect the green and yellow wire to safety (earth) ground at both the router and the supply side of the DC wiring.

• The marked input voltage of –48 VDC for a DC-powered router is the nominal voltage associated with the battery circuit, and any higher voltages are only to be associated with float voltages for the charging function.

• Because the router is a positive ground system, you must connect the positive lead to the terminal labeled RTN , the negative lead to the terminal labeled –48V , and the earth ground to the chassis grounding points.

DC Power Wiring Terminations Warning

WARNING: When stranded wiring is required, use approved wiring terminations, such as closed-loop or spade-type with upturned lugs. These terminations must be the appropriate size for the wires and must clamp both the insulation and conductor.

Waarschuwing Wanneer geslagen bedrading vereist is, dient u bedrading te gebruiken die voorzien is van goedgekeurde aansluitingspunten, zoals het gesloten-lus type of het grijperschop type waarbij de aansluitpunten omhoog wijzen. Deze aansluitpunten dienen de juiste maat voor de draden te hebben en dienen zowel de isolatie als de geleider vast te klemmen.

Varoitus Jos säikeellinen johdin on tarpeen, käytä hyväksyttyä johdinliitäntää, esimerkiksi suljettua silmukkaa tai kourumaista liitäntää, jossa on ylöspäin käännetyt kiinnityskorvat. Tällaisten liitäntöjen tulee olla kooltaan johtimiin sopivia ja niiden tulee puristaa yhteen sekä eristeen että johdinosan.

Attention Quand des fils torsadés sont nécessaires, utiliser des douilles terminales homologuées telles que celles à circuit fermé ou du type à plage ouverte avec cosses rebroussées. Ces douilles terminales doivent être de la taille qui convient aux fils et doivent être refermées sur la gaine isolante et sur le conducteur.

Warnung Wenn Litzenverdrahtung erforderlich ist, sind zugelassene

Verdrahtungsabschlüsse, z.B. Ringoesen oder gabelförmige Kabelschuhe mit nach oben gerichteten Enden zu verwenden. Diese Abschlüsse sollten die angemessene Größe für die Drähte haben und sowohl die Isolierung als auch den Leiter festklemmen.

T1600 Core Router Hardware Guide

Avvertenza Quando occorre usare trecce, usare connettori omologati, come quelli a occhiello o a forcella con linguette rivolte verso l'alto. I connettori devono avere la misura adatta per il cablaggio e devono serrare sia l'isolante che il conduttore.

Advarsel Hvis det er nødvendig med flertrådede ledninger, brukes godkjente ledningsavslutninger, som for eksempel lukket sløyfe eller spadetype med oppoverbøyde kabelsko. Disse avslutningene skal ha riktig størrelse i forhold til ledningene, og skal klemme sammen både isolasjonen og lederen.

Aviso Quando forem requeridas montagens de instalação eléctrica de cabo torcido, use terminações de cabo aprovadas, tais como, terminações de cabo em circuito fechado e planas com terminais de orelha voltados para cima.

Estas terminações de cabo deverão ser do tamanho apropriado para os respectivos cabos, e deverão prender simultaneamente o isolamento e o fio condutor.

¡Atención!

Cuando se necesite hilo trenzado, utilizar terminales para cables homologados, tales como las de tipo "bucle cerrado" o "espada", con las lengüetas de conexión vueltas hacia arriba. Estos terminales deberán ser del tamaño apropiado para los cables que se utilicen, y tendrán que sujetar tanto el aislante como el conductor.

Varning!

När flertrådiga ledningar krävs måste godkända ledningskontakter användas, t.ex. kabelsko av sluten eller öppen typ med uppåtvänd tapp.

Storleken på dessa kontakter måste vara avpassad till ledningarna och måste kunna hålla både isoleringen och ledaren fastklämda.

Distance Limitations for Signaling

Improperly installed wires can emit radio interference. In addition, the potential for damage from lightning strikes increases if wires exceed recommended distances or if wires pass between buildings. The electromagnetic pulse (EMP) caused by lightning can damage unshielded conductors and destroy electronic devices. If your site has previously experienced such problems, you might want to consult experts in electrical surge suppression and shielding.

Chapter 43: Electrical Safety Guidelines and Warnings

Radio Frequency Interference

You can reduce or eliminate the emission of radio frequency interference (RFI) from your site wiring by using twisted-pair cable with a good distribution of grounding conductors.

If you must exceed the recommended distances, use a high-quality twisted-pair cable with one ground conductor for each data signal when applicable.

Electromagnetic Compatibility

If your site is susceptible to problems with electromagnetic compatibility (EMC), particularly from lightning or radio transmitters, you might want to seek expert advice.

Strong sources of electromagnetic interference (EMI) can destroy the signal drivers and receivers in the network device and conduct power surges over the lines into the equipment, resulting in an electrical hazard. It is particularly important to provide a properly grounded and shielded environment and to use electrical surge-suppression devices.

CAUTION: To comply with intrabuilding lightning and surge requirements, intrabuilding wiring must be shielded, and the shield for the wiring must be grounded at both ends.

WARNING: The intrabuilding ports of the equipment or subassembly are suitable for connection to intrabuilding or unexposed wiring or cabling only.

The intrabuilding ports of the equipment or subassembly MUST NOT be metallically connected to interfaces that connect to the Outside Plant (OSP) or its wiring. These interfaces are designed for use as intrabuilding interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue 4) and require isolation from the exposed OSP cabling. The addition of primary protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring.
