T4000 Router Description
The Juniper Networks T4000 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
T4000 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 2.0 terabits per second (Tbps), full duplex (4.0 Tbps 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 the
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 T4000 router provides up to a total of 2.4 billion packets per second
(Mpps) of forwarding.

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.
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
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 8 ). 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
8
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.

Chapter 2: T4000 Router System Architecture Overview
• 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
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 10 ):

1.
Packets arrive at an incoming PIC interface.
2.
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.
3.
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.
4.
The Queuing and Memory Interface ASICs pass the data cells to memory for buffering.
5.
The T Series Internet Processor performs the route lookup and forwards the notification to the Queuing and Memory Interface ASIC.
6.
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 13 ).
7.
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.
8.
The destination Switch Interface ASIC sends bandwidth grants through the switch fabric to the originating Switch Interface ASIC.
Copyright © 2013, Juniper Networks, Inc.
Chapter 2: T4000 Router System Architecture Overview
9.
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.
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.

• T4000 Component Redundancy on page 15
T4000 Component Redundancy
The T4000 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 router has five SIBs. For more information, see
“T4000 Switch Interface Board (SIB) Description” on page 46 .
• 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 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. For more information, see “T4000
RE-C1800 Routing Engine Description” on page 40 , “T4000 LCC-CB” on page 37 , and
“T4000 Host Subsystem Description” on page 35 .
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 Junos OS High Availability Library for Routing Devices .
• 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. For more information, see “T4000 SONET Clock
Generators (SCGs) Description” on page 49 .
• 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. For more information, see “T4000 Power System Description” on page 43 .
• 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. For more information, see “T4000 Cooling System Description” on page 21 .

T4000 Router Hardware Guide 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 17 and
Figure 7 on page 18 ):
• 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.
WARNING: The router must be connected to earth ground during normal operation.

T4000 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 19 ). The FPCs install into the midplane from the front of the 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:
18 Copyright © 2013, Juniper Networks, Inc.
Chapter 3: T4000 Hardware Components Overview
• 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.
• Power distribution—The router power supplies are connected to the midplane, which distributes power to all the router components.
• 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.

T4000 Cable Management System
The front cable management system (see Figure 9 on page 20 ) consists of a row of nine semicircular plastic bobbins mounted on the front of the router below the FPC card cage.
The PIC cables pass between the bobbins and into the tray, keeping the cables organized and securely in place. The curvature of the bobbins also helps maintain the proper bend radius for optical PIC cables.
You can pull the front cable management system up and outward to lock it into the maintenance position. This allows you to access the lower fan tray and the front air filter.
Figure 9: Front Cable Management System
20
For T4000 routers connected to a TX Matrix Plus router, you can use the optional rear cable management system (model number CBL-MGR-TXP-3D-LCC) to organize, support, and provide strain relief for the cables connected to the 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 T4000 router, and then toward the top of the chassis, where you can route the cables to the TX Matrix Plus router.
The cable management system adds 9.5 in. (24.1 cm) to the depth of the T4000 chassis, and 2.4 in. (6.2 cm) to the left side of the chassis.
The LCC rear cable management system 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

Chapter 3: T4000 Hardware Components Overview
T4000 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 normal speed. If a fan fails or the ambient temperature rises above a threshold, the speed of the remaining fans is set to full speed. 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.
In additions to the fans, the front fan trays are equipped with a fan tray controller (FTC) board. The FTC board is a transition board that distributes the fan-related signals between the Routing Engine and the fans, and controls the speed as required.

Alarm LEDs
Two large alarm LEDs are located at the upper left of the craft interface. The circular red
LED lights to indicate a critical condition that can result in a system shutdown. The triangular yellow LED lights to indicate a less severe condition that requires monitoring or maintenance. Both LEDs can be lit simultaneously.
A condition that causes an LED to light also activates the corresponding alarm relay contact on the Connector Interface Panel (CIP). The LCD on the craft interface reports the cause of the alarm.
To deactivate red and yellow alarms, press the button labeled ACO/LT (for “alarm cutoff/lamp test”), which is located to the right of the alarm LEDs. Deactivating an alarm turns off both LEDs and deactivates the device attached to the corresponding alarm relay contact on the CIP. However, the LCD continues to report the alarm message until you clear the condition that caused the alarm.
Table 5 on page 26 describes the alarm LEDs and alarm cutoff button in more detail.

Chapter 3: T4000 Hardware Components Overview both 10- and 100-Mbps connections. Two small LEDs on the left edge of the port indicate the connection in use: the yellow LED lights for a 10-Mbps connection, and the green LED lights for a 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.
T4000 Alarm Relay Contacts
The CIP has two alarm relay contacts for connecting the router to external alarm devices
(see Figure 15 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

T4000 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.
T4000 FPC Function
FPCs house the PICs that connect the T4000 Core Router to network media. The main function of an FPC is to connect the PICs installed in it to the other T4000 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 5 FPCs installed, the Packet
Forwarding Engines can forward up to 4000 million packets per second (Mpps) for all packet sizes. The T4000 Core Router provides up to 2000 gigabits per second (Gbps), full duplex switching (4000 Gbps of any-to-any, nonblocking, half-duplex switching).
30 Copyright © 2013, Juniper Networks, Inc.
Chapter 3: T4000 Hardware Components Overview
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.
T4000 FPC Components
Each FPC consists of the following components:
• FPC card carrier
• One or two Packet Forwarding Engines
• Each T1600-FPC4-ES has two Packet Forwarding Engines. Each Packet Forwarding
Engine consists 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 T4000-FPC5-3D or T4000-FPC5-LSR has two Packet Forwarding Engines.
Each Packet Forwarding Engine consists of a Packet Processing ASIC, Interface ASIC, and Switch Interface ASIC.
• Processor Mezzanine Board (PMB), which includes a 1.2-GHz CPU, system controller,
4 GB of DDR3 RAM, and two 10/100/1000Mbps three-speed Ethernet interfaces
• Two LEDs— OK and FAIL —located on the craft interface above the FPC, that display the status of the FPC

T4000 Host Subsystem Description
The host subsystem provides the routing and system management functions of 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.
NOTE: You can install one or two host subsystems on the router. 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.

T4000 Control Board Description
The T4000 chassis supports up to two control boards. The Routing Engine requires an adjacent control board to provide control and monitoring functions for the router. These functions include determining Routing Engine mastership, controlling power and reset for the other 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.

T4000 Routing Engine Description
The Routing Engine runs Junos OS. The software processes that run on the Routing Engine maintain the routing tables, manage the routing protocols used on the router, control the router interfaces and 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).
The T4000 router supports the Routing Engine in Table 14 on page 39 .

T4000 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.
The router supports various PICs, including ATM, Ethernet, 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.
PICs are hot-removable and hot-insertable. 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 and Type 5 PICs have an upper ejector handle and a lower ejector handle.
Table 16 on page 42 indicates the number of PICs supported by each FPC.

SCG Slots
The SCGs are installed into the upper rear of the chassis in the slots labeled SCG0 and
SCG1 .
SCG Function
SCGs provide 19.44-MHz Stratum 3 clock signal for the SONET/SDH interfaces on the router.
SCG Redundancy
One SCG is shipped as part of the standard router configuration, but up to two SCGs can be installed to provide redundancy. A nonredundant SCG is hot-pluggable. For redundant
SCGs, the master SCG is hot-pluggable. If the master SCG is functioning, the backup
SCG is hot-removable and hot-insertable. Removing the backup SCG does not affect the functioning of the router. Taking the master SCG offline might result in a brief loss of
SONET clock lock while the backup SCG becomes the master.
Supported SCGs
The T4000 router supports the SCG in Table 23 on page 50 .

• Overview of Installing the T4000 Router on page 55
Rack Requirements for the T4000 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 30 on page 59 .
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
Industry Association ( http://www.eia.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.
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 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 30: Typical Open-Frame Rack
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.

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 “T4000
Clearance Requirements for Airflow and Hardware Maintenance” on page 59 .
2.
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.
3.
Using the lift, position the chassis in front of the rack or cabinet, centering it in front of the mounting shelves.
4.
Lift the chassis approximately 0.75 in. above the surface of the mounting shelves, and position it as close as possible to the shelves.
Copyright © 2013, Juniper Networks, Inc.
79
T4000 Router Hardware Guide
5.
Carefully slide the chassis onto the mounting shelves so that the bottom of the chassis and the mounting shelves overlap by approximately 2 inches.
6.
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.
7.
Move the lift away from the rack.
8.
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.
9.
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.

99
T4000 Router Hardware Guide
WARNING: To prevent injury, keep your back straight and lift with your legs, not your back. Avoid twisting your body as you lift. Balance the load evenly, and be sure that your footing is solid.
6.
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 router 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.
7.
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.
8.
Loosen the captive screws on the installation handle completely, and remove the handle from the chassis.
9.
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.

Connecting PIC Cables to the T4000 Router
The router supports PICs that use various kinds of network cable, including multimode and single-mode fiber-optic cable.
You connect PICs to the network by plugging in network cable. To connect cable to the
PICs (see Figure 66 on page 117 , which shows a fiber-optic PIC):
1.
Have ready a length of the type of cable used by the PIC. For information about the type of cable used by each PIC, see the T4000 Interface Module Reference . For cable specifications, see the “Network Cable and Transceiver Overview for T Series Routers” on page 345 .
2.
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.
3.
Insert the cable connector into the cable connector port on the PIC faceplate.
4.
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
116 Copyright © 2013, Juniper Networks, Inc.
Chapter 12: Connecting the T4000 Router to External Devices as it hangs to the floor. Place excess cable out of the way in a neatly coiled loop.
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.

Tools and Parts Required to Provide Power to the T4000 Router
To connect the router to power, you need the following tools and parts:
• DC-powered routers: 7/16-in. (11 mm) hexagonal-head external drive nut driver, with a torque range between 23 lb-in. (2.6 Nm) and 25 lb-in. (2.8 Nm), for tightening nuts to terminal studs on each power supply on a DC-powered router.
• Torque-controlled tool.
CAUTION: You must use an appropriate torque-controlled tool to tighten the nuts. Applying excessive torque damages the terminal studs and the power supply. The absolute maximum torque that may be applied to this nut is 45 in-lb (5.0 Nm).
• DC power cables and lugs. See “T4000 DC Power Cable and Lugs Specifications” on page 341 .

Connecting DC Power to the T4000 Router (Six 60-A Inputs)
You connect DC power to the router by attaching power cables from the DC power sources to the terminal studs on the power supply faceplates. You must provide power cables
(the cable lugs are supplied with the router).
CAUTION: All connected inputs on the DC power supply in slot PEM0 must be powered by dedicated power feeds derived from feed A, and all connected inputs on the DC power supply in slot PEM1 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: We recommend that the positive (+) DC source power cables for the
RTN (return) terminals be 2.6 in. (6.6 cm) longer than the negative (–) DC source power cables for the –48 V (input) terminals.
CAUTION: You must use an appropriate torque-controlled tool to tighten the nuts. Applying excessive torque damages the terminal studs and the power supply. The absolute maximum torque that may be applied to this nut is 45 lb-in. (5.0 Nm).
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.
To connect DC source power cables to the router, follow this procedure for each DC power supply:
1.
Verify that a properly rated customer site circuit breaker for each DC power cable has been installed. See the DC power electrical safety guidelines for your router for more information.
2.
Switch off the customer site circuit breakers. Ensure that the voltage across the DC power source cable leads is 0 V and that there is no chance that the cable leads might become active during installation.

Connecting DC Power to the T4000 Router (Three 80-A DC Power Cables to Six 60-A Inputs)
You connect DC power to the router by using a terminal jumper to attach one DC power cable from the DC power source to two terminal studs on the power supply faceplate.
Use the terminal jumper kit (model number PWR-T-BUS-BAR-S) to perform this procedure. The terminal jumper kit contains the terminal jumpers and the new clear plastic cover required to accommodate the terminal jumpers. Six terminal jumpers are required for each power supply. You must provide power cables (the cable lugs are supplied with the router).
CAUTION: When using a terminal jumper for this procedure, terminate only a single DC power cable to the two input terminals using the terminal jumper as shown in Figure 83 on page 137 and Figure 84 on page 138 . Do not connect two DC power cables using a terminal jumper to two inputs as shown in
Figure 80 on page 134 . Connecting two DC power cables using a terminal jumper to two inputs will cause a short across the inputs and trip your external circuit breaker.
Copyright © 2013, Juniper Networks, Inc.
133
T4000 Router Hardware Guide
Figure 80: Incorrect Cable Connection to INPUT 1
134
CAUTION: All connected inputs on the DC power supply in slot PEM0 must be powered by dedicated power feeds derived from feed A, and all connected inputs on the DC power supply in slot PEM1 must be powered by dedicated power feeds derived from feed B. This configuration provides the commonly deployed A/B feed redundancy for the system.
CAUTION: You must use an appropriate torque-controlled tool to tighten the nuts. Applying excessive torque damages the terminal studs and the power supply. The absolute maximum torque that may be applied to this nut is 45 lb-in. (5.0 Nm).
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.
NOTE: We recommend that the positive (+) DC source power cables to be connected to the RTN (return) terminals be 2.6 in. (6.6 cm) longer than the negative (–) DC source power cables to be connected to the –48 V (input) terminals.

Chapter 13: Providing Power to the T4000 Router
To connect 80-A DC source power cables to six inputs using a terminal jumper, follow this procedure for each DC power supply:
1.
Check your planned hardware configuration, and verify that three 80-A DC source power cables will provide sufficient power. See the DC power requirements for your router for more information.
2.
Verify that a properly rated customer site circuit breaker for each DC power cable has been installed. See the DC power electrical safety guidelines for your router for more information.
3.
Switch off the customer site circuit breakers. Ensure that the voltage across the DC power source cable leads is 0 V and that there is no chance that the cable leads might become active during installation.
4.
Verify that a licensed electrician has attached appropriate cable lugs to the DC power cables. See the DC power cable and lug specifications for your router for more information.
5.
Switch the power switch on the power supply faceplate to the standby position.
6.
Remove the clear plastic cover protecting the terminal studs on the faceplate.
NOTE: You will replace this cover with the new cover provided in the terminal jumper kit (model number PWR-T-BUS-BAR-S). The new cover is labeled 2 in Figure 86 on page 140 .
7.
Remove the nut and washer from each power terminal stud to be connected. If no washers and nuts are already installed, they should be in the accessory box.
8.
Remove the captive screws on all three cable restraints on the right edge of the power supply faceplate (using a Phillips (+) screwdriver, number 2).
9.
Place one terminal jumper over the negative (–) DC INPUT 0 and INPUT 1 terminals on the right.

Powering On the T4000 Router
To power on the DC-powered T4000 router:
1.
Verify that the power supplies are fully inserted in the chassis and that the captive screws on their faceplates are tightened.
2.
Verify that the source power cables are connected to the appropriate terminal: the positive (+) source cable to the return terminal (labeled RTN ) and the negative (–) source cable to the input terminal (labeled –48V ).
3.
Verify that an external management device is connected to one of the Routing Engine ports on the CIP ( AUXILIARY , CONSOLE , or ETHERNET ).
NOTE: If you are powering on the router for the first time, the AUXILIARY and ETHERNET ports do not function until after the initial configuration procedure.
4.
Turn on the power to the external management device.
5.
Switch on the dedicated customer site circuit breakers to provide power to the DC power cables. Follow your site’s procedures.
6.
Verify that the INPUT PRESENT LED for each input on the DC power supply faceplate is lit steadily green, indicating that the inputs are receiving power.
7.
Switch the power switch on the power supply to the ON position ( — ). The DC OK LED blinks momentarily, then lights steadily.
NOTE: After a power supply is powered on, it can take up to 60 seconds for status indicators—such as the LEDs on the power supply, the command output displays, and messages on the LED display on the craft interface—to indicate that the power supply is functioning normally. Ignore error indicators that appear during the first 60 seconds.
8.
Verify that the DC OK LED on the DC power supply faceplate is lit steadily, indicating that power supply is correctly installed and functioning properly.
9.
On the external management device connected to the Routing Engine, monitor the startup process to verify that the router has booted properly.
10.
Repeat the procedure for the other power supply.

When you connect three 80-A DC power cables to six inputs using terminal jumpers to each power supply, you must specify the input current in the software. In addition, you must also indicate that six input feeds are used. If the number of physical input feeds receiving power does not match the number of configured inputs, the router displays an alarm message.
1.
Configure the number of input feeds to indicate that six feeds are used to connect the three 80-A DC power cables by means of terminal jumpers.
[edit] user@host# set chassis pem feeds 6
NOTE: The default number of input feeds is 6.
2.
Configure the input current to indicate that 40-A is used to provide input current. Each
80-A DC power cable connects to two inputs by means of a terminal jumper, with each input receiving approximately 40 amps.
[edit] user@host# set chassis pem input-current 40
150 Copyright © 2013, Juniper Networks, Inc.
Chapter 14: Configuring Junos OS
NOTE: The default input current is 60-A.
3.
(Optional) If the power has been underprovisioned for your configuration, some FPCs might not be brought online if the available power capacity is exceeded. When you reboot the router, FPCs are brought online based on the default setting of the fru-poweron-sequence command. You can use the fru-poweron-sequence command to change the default order in which FPCs are brought online when the router is rebooted.
[edit] user@host# set chassis fru-poweron-sequence fru-poweron-sequence
NOTE: The default is the numerical order of the FPC slots (0 through 7).
4.
(Optional) Use the show statement to display the configuration to verify that it is correct.
[edit] user@host# show pem { feeds 6; input-current 40;
}
5.
Commit the configuration to activate it on the router and exit configuration mode.

Overview of Preparing to Upgrade to a T4000 Router
To prepare to upgrade to a T4000 router:
1.
Prepare the installation site for the T4000 router.
See “Overview of Preparing the Site for the T4000 Router” on page 57 .
2.
Determine which model numbers of the following components are already installed.
See “Checking the Hardware Version of T640 or T1600 Components” on page 156 .
• Routing Engines: RE-DUO-C1800-8G or RE-DUO-C1800-16G (supported on T640 or T1600 router)
• Control boards: CB-LCC (supported on T640 or T1600 router)
• Rear fan tray: FAN-REAR-TXP-LCC (supported on T1600 router only)
• Power supplies: PWR-T-6-60-DC (supported on T640 or T1600 router)
3.
Order the required hardware.
The hardware upgrade kit includes two LCC-CBs, two RE-DUO-CI800-8G Routing
Engines, five SIB-I-T4000 SIBs, one FAN-REAR-TXP-LCC rear fan trays, two
FANTRAY-T4000 front fan trays, and two PWR-T-6-60-DC power supplies. If the required control boards, Routing Engines, rear fan tray, or power supplies are already installed in the T640 or T1600 router, you can also order the other hardware components separately.
See the “T4000 Upgrade Kit” on page 164 .
4.
Review all safety guidelines and warnings for both the T4000 router and T1600 router or T640 Router.

See “General Safety Guidelines for Juniper Networks Devices” on page 293 and “General
Safety Warnings for Juniper Networks Devices” on page 294 .
5.
Upgrade the software on the T1600 router or T640 router to Junos OS Release 12.1
or later. Support of some hardware or software features require Junos OS Release
12.1R2 or later. For information about upgrading the software, see the Installation and
Upgrade Guide .
6.
Delete unsupported configurations from the T640 or T1600 router.
For example, the following CoS configuration is not supported for T4000 routers:
Hierarchy Level [edit class-of-service schedulers scheduler-name] drop-profile-map loss-priority (any | low | medium-low | medium-high | high) protocol (any| non-tcp | tcp) drop-profile profile-name.
For the T4000 router, any is the only protocol option supported for the following statement. The non-tcp and tcp options are not supported,
Hierarchy Level [edit class-of-service schedulers scheduler-name] drop-profile-map loss-priority (any | low | medium-low | medium-high | high) protocol any drop-profileprofile-name.

• Replacing a T4000 Six-Input DC Power Supply Front Air Filter on page 264
• Replacing a T4000 Six-Input DC Power Supply Side Air Filter on page 265
We recommend that you use spare filter elements within 1 year of manufacture. Check the date of manufacture printed on the filter. Store spare filter elements in a dark, cool, and dry place. Storing the filter elements at higher temperatures, or where they can be exposed to ultraviolet (UV) radiation, hydrocarbon emissions, or vapors from solvents, can significantly reduce their life.
CAUTION: Always keep the 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.

Maintaining PIC Cables
Purpose For optimum router performance, verify the condition of the PIC cables.
Action On a regular basis:
• 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, which 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 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 T4000 Power System
Purpose For optimum router performance, verify the condition of the power supplies and grounding.
Action On a regular basis:
• 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
For a list of possible alarm messages, see “Troubleshooting the T4000 Power System” on page 204 .
• Make sure that the DC power 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 is accumulating near the router.
To review grounding and site wiring requirements for the router, see “T4000 DC Power
Cable and Lugs Specifications” on page 341 and “T4000 Chassis Grounding Cable and
Lug Specifications” on page 335 .
• Use the show chassis environment pem command to verify the status of the power supplies.
• Routinely check the status LEDs on the power supply faceplates to verify that the power supplies are functioning normally. During normal operation:
• The blue DC OK LEDs light to indicate that the power supplies are functioning normally.
• Each green INPUT PRESENT LED on a DC power supply lights when the input is receiving source DC power.

Troubleshooting the T4000 Cooling System
Problem The following alarms, LEDs, and other conditions indicate a problem with the cooling system:
• A red alarm indicates that the temperature of the router exceeds the maximum
(“temperature hot”) threshold.
• Automatic shutdown of the power supplies can be caused by the temperature of the router exceeding the maximum (“temperature hot”) threshold. The control board turns off the power supplies because the router temperature exceeds the acceptable maximum.
• A red alarm indicates that a fan failed.
• A yellow alarm indicates that the router temperature exceeds the “temperature warm” threshold.
• A yellow alarm indicates that one of the fan trays was removed.
• One or more fans in a fan tray function at full speed. The control boards constantly monitor the temperatures detected by sensors on the midplane and router components, adjusting the speed of the fans as necessary. If one fan fails, the host subsystem adjusts the speed of the remaining fans to maintain proper cooling.

• Place your hand near the exhaust vents at the rear of the chassis to determine whether the fans are pushing air out of the chassis.
Verify that the room temperature is within acceptable limits.
•
•
Verify that there is sufficient air flow.
Verify that the cooling system in the chassis is operating properly.
Temperature sensor failure
A temperature sensor failed.
Contact JTAC.
Temperature Warm The chassis temperature exceeded the recommended warm temperature threshold.
•
•
Place your hand near the exhaust vents at the rear of the chassis to determine whether the fans are pushing air out of the chassis.
Verify that the room temperature is within acceptable limits.
•
•
Verify that there is sufficient air flow.
Verify that the cooling system in the chassis is operating properly.
Solution To troubleshoot the cooling system:
1.
Check the red and yellow alarm LEDs on the craft interface.
2.
Find the source of the problem by looking at the craft interface display. The number of alarm conditions, as well as the source of each alarm, appears on the screen. If the craft interface display lists only one fan failure and the other fans are functioning normally, the fan is probably faulty and you need to replace the fan tray.
3.
Use the show chassis alarms command to get information about the source of an alarm condition: user@host> show chassis alarms
For information about the alarms, see Table 30 on page 193 and Table 31 on page 194 .
4.
Use the show chassis fan command to verify that the status of each fan is OK and that the output display indicates that each of the fans are Spinning at normal speed .

Troubleshooting the T4000 Power System
Problem The following alarms, LEDs, and other conditions indicate a problem with the power system:
• If all power supplies have failed, the system temperature might have exceeded the threshold, causing the system to shut down.
• Table 36 on page 206 lists alarms for the power system, including the solution.
• Table 37 on page 207 lists abnormal LED states for the power supplies, including the solution.
Solution 1.
Check the display on the craft interface to determine the source of a yellow or red alarm (see Table 36 on page 206 ). 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 PEM1 , 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.
2.
Issue the show chassis alarms command to check for power system alarms. See
Table 36 on page 206 .
3.
Check the LEDs on each six-input DC power supply faceplate. See Table 37 on page 207 .
4.
Use the show chassis environment pem command.

Verify that the customer site circuit breaker for each input 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 PEM1 must be powered by dedicated power feeds derived from feed B. This configuration provides the commonly deployed
A/B feed redundancy for the system.
6.
Verify that the DC power cables from the power source to the router are not damaged.
If the insulation is cracked or broken, immediately replace the DC power cable .
7.
Connect the power supply to a different power source with a new DC power cable. 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. If the DC OK LED on the installed spare still does not light—The replaced power supply might also be faulty. To return it for replacement, see “Contacting Customer Support” on page 353 .
8.
If you cannot determine the cause of the problem or need additional assistance, see
“Contacting Customer Support” on page 353 .
In Table 36 on page 206 , the text in the column labeled ”LCD Message” appears in the display of the craft interface. The text in the column labeled “CLI Message” appears in the output from the show chassis alarms command.

•
If the customer site circuit breakers are off, switch them on.
If the customer circuit breakers are switched on but the input is not receiving power, switch off the customer site circuit breakers, and reinstall the DC power source cables.
The input is okay, but the power supply might not be properly inserted, or there is a fault (such as insufficient airflow or faulty output).
The LED blinks when the power supply is initializing; but if it continues to blink, verify that the power supply is installed properly and that the power supply switch is in the on position.
If the LED continues to blink, replace the power supply.
The power supply is shut down because of excessive internal tempature.
Check the power supply fan and air filters to be sure they are functioning and providing sufficient airflow through the power supply and that the power supply is operating within the specified ambient temperature.
Wait approximately 30 to 60 minutes and turn on the power supply. If the over temperature condition persists, replace the power supply.
Use the show chassis environment pem command to view the temperature.

T4000 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.
Before you replace a component in the host subsystem, you must take the host subsystem offline.
Table 40 on page 216 lists the FRUs for the router.

Replacing a T4000 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.
242 Copyright © 2013, Juniper Networks, Inc.
Chapter 19: Replacing T4000 Router Hardware Components
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 33.5 lb (15.1 kg).
Each FPC slot not occupied by an FPC must be covered by an FPC blank panel. An FPC blank panel weighs 9 lb (4.2 kg).

2.
Installing a T4000 FPC on page 245
Removing a T4000 FPC
To remove an FPC (see Figure 110 on page 245 ):
1.
Place an electrostatic bag or antistatic mat on a flat, stable surface.
2.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
3.
Before removing an FPC, record its location in the chassis so that you can reinstall each FPC in the correct slot.
4.
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
5.
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.
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.
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.

T4000 Router Hardware Guide
6.
If necessary, remove each installed PIC from the FPC.
7.
After you remove each PIC, immediately place it on an antistatic mat or in an electrostatic bag.
Do not stack components 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.
8.
Simultaneously turn both the ejector handles counterclockwise to unseat the FPC.
9.
Grasp the handles, and slide the FPC straight out of the card cage halfway.
10.
Place one hand around the front of the FPC (the PIC housing) and the other hand under it to support it. Slide the FPC completely out of the chassis, and place it on the antistatic mat or in the electrostatic bag.
CAUTION: The weight of the FPC is concentrated in the back end. Be prepared to accept the full weight—up to 33.5 lb (15.1 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.
11.
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.

Insert the appropriate cable into the cable connector ports on each PIC on the FPC.
Secure the cables so that they are not supporting their own weight. Place excess cable out of the way in a neatly coiled loop, using the cable management system. Placing fasteners on a 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.
18.
Use one of the following methods to bring the FPC online:
• Press and hold the FPC online/offline button until the green OK LED next to the button lights steadily, in about 5 seconds. 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 online
CAUTION: After the OK LED lights steadily, wait at least 30 seconds before removing the FPC again, removing an FPC from a different slot, or inserting an FPC in a different slot.
You can also verify correct FPC and PIC functioning by issuing the show chassis fpc and show chassis fpc pic-status commands.

Taking the T4000 Host Subsystem Offline
Before you replace a control board, a Routing Engine, and some Routing Engine components, 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.
248 Copyright © 2013, Juniper Networks, Inc.
Chapter 19: Replacing T4000 Router Hardware Components
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.
NOTE: For information about high availability features, configuring graceful switchover and nonstop active routing, see the Junos OS High Availability
Library for Routing Devices.
Table 42 on page 249 explains the effect of taking the host subsystem offline.

Table 42: 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.
NOTE: Graceful Routing Engine switchover (GRES) is supported on Junos
OS Release 12.1R2 and later for T4000 routers.
• 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 12.1R2 and later for T4000 routers,
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.

To take a host subsystem offline:
1.
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.
• Use the show chassis routing-engine command to determine which Routing Engine is the master. In this example, the master Routing Engine in Slot 0 is designated

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
Copyright © 2013, Juniper Networks, Inc.
251
T4000 Router Hardware Guide
3.
To halt the router: 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.
NOTE: The SIBs might continue forwarding traffic for approximately 5 minutes after the request system halt command has been issued.
4.
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.
5.
Verify that the control board is offline: user@host> show chassis environment cb 0

Removing a T4000 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 approximately 2 lb (0.9 kg).
To remove a PIC (see Figure 112 on page 255 ):
1.
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.
2.
Attach an electrostatic discharge ESD grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
3.
Use one of the following methods to take the PIC offline:
• Issue the following CLI command:
• user@host> request chassis pic fpc-slot fpc-slot pic-slot pic-slot offline
Press and hold the online/offline button until the status LED on the PIC goes out
(about 5 seconds). The label for the status LED varies for each PIC. See the T4000
Interface Module Reference for more information about the PIC LEDs.
For a Type 4 or Type 5 PIC, use a narrow-ended tool that fits inside the opening that leads to the button.
4.
Label the cables connected to the PIC so that you can later reconnect each cable to the correct PIC.
5.
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.
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.
6.
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

Removing a T4000 Routing Engine
The router can have one or two Routing Engines. They are located in the upper rear of the chassis in the slots marked RE0 and RE1 . Each Routing Engine can weigh up to
2.4 lb (1.1 kg). The backup Routing Engine is hot-removable and hot-insertable.
CAUTION: Before you replace a Routing Engine, you must take the host subsystem offline. If there is only one host subsystem, taking the host subsystem offline shuts down the router. If the Routing Engine to be replaced is currently functioning as the master Routing Engine, switch it to be the backup before removing it.
To remove a Routing Engine (see Figure 125 on page 268 ):
1.
Take the host subsystem offline.
2.
Place an electrostatic bag or antistatic mat on a flat, stable surface.
3.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
4.
Loosen the captive screws on the corners of the Routing Engine cover.
5.
Grasp the Routing Engine cover by its edges, and pull it free from the chassis (see
Figure 124 on page 268 ).
6.
If applicable, loosen the screws on the extractor handles at either end of the Routing
Engine faceplate, using a Phillips screwdriver.
7.
Press the red tabs on the ejector handles on both sides of the Routing Engine faceplate.
8.
Flip the ejector handles outward to unseat the Routing Engine.
9.
Grasp the Routing Engine by the ejector handles, and slide it about halfway out of the chassis.
10.
Place one of your hands underneath the Routing Engine to support it, and slide it completely out of the chassis.
11.
Place the Routing Engine on the antistatic mat.
12.
If you are not replacing the Routing Engine now, reinstall the Routing Engine cover, and tighten the screws on the corners of the cover to secure it to the chassis.

Preventing T4000 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 143 on page 297 and Figure 144 on page 298 .
• 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 145 on page 298 ). If you are returning a component, place it in an electrostatic bag before packing it.

• Fire Suppression Equipment on page 299
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 should 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 power off 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
2
) 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.
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.
Copyright © 2013, Juniper Networks, Inc.
299
T4000 Router Hardware Guide
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.

• T4000 DC Power Requirements on page 338
Chassis Lifting Guidelines
The weight of a fully configured router is about 663.6 lb (301.0 kg). Observe the following guidelines for lifting and moving the router:
• 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 4 people are 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.

T4000 General Laser Safety Guidelines
Devices with single-mode optical interfaces are equipped with laser transmitters, which are considered a 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.

• Electromagnetic Compatibility on page 319
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.
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.
318 Copyright © 2013, Juniper Networks, Inc.
Appendix A: Router Safety and Regulatory Compliance Information
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 port(s) of the equipment or subassembly is suitable for connection to intrabuilding or unexposed wiring or cabling only.
The intrabuilding port(s) of the equipment or subassembly MUST NOT be metallically connected to interfaces that connect to the 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.

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: Failure to provide the required circuit breaker or current-limiting fuse for each DC power cable can cause injury or damage to equipment.
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 100 A (–48 VDC) maximum for the six-input DC power supply, or as required by local code. 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 a 100 A circuit breaker or current-limiting fuse rated for each 80 A DC power cable
• 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.
• 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.
• 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 60 A @ –48 VDC per input for the six-input DC power supply.
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 60 A DC power cables or 100 A for 80 A DC power cables. .
NOTE: Only 60 A feeds are currently supported.
• 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.

Appendix A: Router Safety and Regulatory Compliance Information
• 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.
• 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.

T4000 Router Hardware Guide
T4000 Power Management (Four 60-A Cables on a Six-Input DC Power Supply)
For Junos OS Release 12.3 and later, the power management feature ensures that the router has enough power to support an FPC before the FPC is brought online. To configure the power management feature, see “Configuring DC Power on a T4000 Router” on page 148 . Depending on the type of FPCs installed, the router might not support a fully loaded chassis when you connect four 60-A DC power cables to a six 60-A input power supply.
If the power is underprovisioned for your hardware configuration, power management limits the number of FPCs brought online based on the following rules:
• When a T1600 Enhanced Scaling FPC4 (Model: T1600-FPC4-ES) is installed, the maximum number of FPCs that can be online is six.
• When there are no T1600-FPC4-ES installed, the maximum number of FPCs that can be online is seven.
For example, if there are six online FPCs and you insert a T1600-FPC4-ES, the power management feature will not power on the FPC.
NOTE: In the event of a chassis restart, master switchover, or router reboot, the power management feature powers on the FPCs based on the setting of the set chassis fru-poweron-sequence command.
CAUTION: If you do not configure the power management feature and you are connecting four 60-A DC power cables to the six-input power supply and the maximum power draw is exceeded, FRU states might change from Online to Offline or Present, or the interfaces might flap, or some traffic might drop.

WARNING: For field-wiring connections, use copper conductors only.
WARNING: DC 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 router includes cable lugs for 4-AWG (21.2 mm
2
) cable lugs. 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.

T4000 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 0 must be powered by dedicated power feeds derived from feed A, and all inputs on the DC power supply in slot 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.

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. LEDs are not coherent sources, however. 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 (HOL) 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. It is consequently more expensive.
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. While 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 in time. The following two types of dispersion can affect an optical data link:
• Chromatic dispersion—Spreading of the signal in time resulting from the different speeds of light rays.
• Modal dispersion—Spreading of the signal in 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.
Copyright © 2013, Juniper Networks, Inc.
347
T4000 Router Hardware Guide
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 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
T
) and minimum receiver sensitivity (P
R
),
):
P
B
= P
T
– P
R
The following hypothetical power budget equation uses values measured in decibels
(dB) and decibels referred to one milliwatt (dBm):

= P

= –15 dBm – (–28 dBm)

Calculating Power Margin for Fiber-Optic Cable
After calculating a link's power budget you can calculate the power margin (P
M
), which represents the amount of power available after subtracting attenuation or link loss (LL) from the power budget (P
B
). A worst-case estimate of P
M assumes maximum LL:
P
M
= P
B
– LL
A P
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 (HOL), modal and chromatic dispersion, connectors, splices, and fiber attenuation.
Table 52 on page 349 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 example uses the estimated values in Table 33 to calculate link loss (LL) for a 2-km-long multimode link with a power budget (P
B
) of 13 dB:
• Fiber attenuation for 2 km @ 1.0 dB/km= 2 dB
• Loss for five connectors @ 0.5 dB per connector = 5(0.5 dB) = 2.5 dB
• Loss for two splices @ 0.5 dB per splice =2(0.5 dB) = 1 dB
• Higher-order mode loss = 0.5 dB
• Clock recovery module = 1 dB
The power margin (P
M
) is calculated as follows:
P
M
= P
B
– LL
P
M
= 13 dB – 2 km (1.0 dB/km) – 5 (0.5 dB) – 2 (0.5 dB) – 0.5 dB [HOL] – 1 dB [CRM]
P

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

The following sample calculation for an 8-km-long single-mode link with a power budget
(P
B
) of 13 dB uses the estimated values from Table 52 on page 349 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

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

= 13 dB – 4 dB – 3.5 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.

Packing the T4000 Router for Shipment
To pack the router for shipment:
1.
Retrieve the shipping crate and packing materials in which the router was originally shipped. If you do not have these materials, contact your Juniper Networks representative about approved packaging materials.
2.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
3.
On the console or other management device connected to the master Routing Engine, enter CLI operational mode. To power off the router, see “Powering Off the T4000
Router” on page 142 .
4.
Disconnect power from the router. .
5.
Remove the cables that connect to all external devices. For instructions, see “Removing a T4000 Management Ethernet Cable” on page 226 , “Removing a T4000 Console or
Auxiliary Cable” on page 224 , and “Replacing the T4000 Alarm Relay Wires” on page 224 .
6.
Remove all field replaceable units (FRUs) from the router.
7.
Remove the router from the rack:

T4000 Router Hardware Guide
• If you are using a mechanical lift, place the lift platform under the router, unscrew and remove the mounting screws from the rack, and move the router to the shipping crate.
• If you are not using a mechanical lift:
• If the router weight is fully supported by a shelf or another router, unscrew and remove the mounting screws from the rack. Four people can then lift the router and move it to the shipping crate.
• If the router weight is not fully supported by a shelf or another router, four people should grasp the router while another person unscrews and removes the mounting screws from the rack. The lifters can then move the router to the shipping crate.
8.
Place the router into the shipping crate or onto the pallet. If on a pallet, bolt the router to the pallet.
9.
Cover the router with an ESD bag, and place packing foam on top of and around the router.
10.
Replace the accessory box on top of the packing foam.
11.
Securely tape the box closed or place the crate cover over the router.
12.
Write the Return Materials Authorization (RMA) number on the exterior of the box to ensure proper tracking.

Packing the T4000 Router Components for Shipment
To pack and ship individual components:
• When you return components, make sure they are adequately protected with packing materials and packed so that the pieces are prevented from moving around inside the carton.
• Use the original shipping materials if they are available.
• Place individual boards in electrostatic bags.
• Write the Return Materials Authorization (RMA) number on the exterior of the box to ensure proper tracking.
CAUTION: Do not stack any of the router components.
