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.

T4000 Component Redundancy on page 7
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 79
.
• 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
RE-C1800 Routing Engine Description” on page 34
,
, and
“T4000 Host Subsystem Description” on page 29 .
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
Generators (SCGs) Description” on page 20
.
• 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 75 .
• 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 25 .

T4000 Cable Management System
The front cable management system (see
) 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.
Copyright © 2018, Juniper Networks, Inc.

T4000 Core Router Hardware Guide
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 5: Front Cable Management System
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
T4000 rear cable management system.

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

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).

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).
Copyright © 2018, Juniper Networks, Inc.
57
T4000 Core Router Hardware Guide
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
• FPC online/offline button, located on the craft interface above the FPC

Regardless of whether you are holding an FPC vertically or horizontally, this document uses the same terms for all four edges of the FPC (see
• Faceplate—Edge of the FPC that has slots into which you insert the PICs
• Connector edge—Edge opposite the faceplate; this edge has the connectors that attach to the midplane
• Top edge—Edge at the top of the FPC when it is vertical

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 1 and Type 2 PICs have captive screws at their upper and lower corners. Type 3 PICs have an upper ejector handle and a lower captive screw. Type 4 and Type 5 PICs have an upper ejector handle and a lower ejector handle.

Power Supply Slots
The T4000 router has two redundant, load-sharing power supplies, located at the lower rear of the chassis in slots PEM0 and PEM1 (top to bottom). Power supplies are hot-removable and hot-insertable.
Power Supply Function
The power supplies connect to the midplane, which distributes the different output voltages produced by the power supplies to the T4000 router components, depending on their voltage requirements.
Supported Power Supplies
The T4000 router supports the power supply in

T4000 Core Router Hardware Guide
Power Supply Components
Each six-input DC power supply weighs approximately 39.7 lb (18.0 kg) and consists of six inputs, two blowers, a front and side air filter, and LEDs to monitor the status of the power supply. Each power supply is cooled by its own internal cooling system.
shows the six-input DC power supply.
The six-input DC power supply inputs are labeled INPUT 0 , INPUT 1 , INPUT 2 , INPUT 3 ,
INPUT 4 , and INPUT 5 , from top to bottom. Each 60 A input consists of –48 VDC and return.
NOTE: There are no circuit breakers or passive fuses in the router.

Fan trays INPUT 0
INPUT 1 through INPUT 5 FPCs, Routing Engines, control boards, SIBs, craft interface, SCGs, and other components in the router.
When the T4000 router is operating normally and both power supplies are switched on, load sharing between them occurs automatically. When one power supply fails or is turned off, the other power supply immediately assumes the entire electrical load for the system. A single power supply can provide full power for as long as the router is operational. For power management of the T4000 router, see
Management (Three 80-A Cables on a Six-Input DC Power Supply)” on page 103
and

T4000 Switch Interface Board (SIB) Description
SIBs create the switch fabric for the T4000 Core Router. Each T4000 router contains five SIBs, located at the center rear of the chassis in the slots labeled SIB0 through SIB4
(top to bottom). One of the five SIBs acts as a backup to the remaining four SIBs. If a SIB fails, the backup SIB becomes active, and traffic forwarding continues without any degradation. When the failed SIB is replaced, it becomes the new backup. SIBs are hot-insertable and hot-removable.
The T4000 router supports the SIB listed in

General Site Guidelines
Efficient device operation requires proper site planning and maintenance and proper layout of the equipment, rack or cabinet (if used), and wiring closet.
To plan and create an acceptable operating environment for your device and prevent environmentally caused equipment failures:
• Keep the area around the chassis free from dust and conductive material, such as metal flakes.
• Follow prescribed airflow guidelines to ensure that the cooling system functions properly and that exhaust from other equipment does not blow into the intake vents of the device.
• Follow the prescribed electrostatic discharge (ESD) prevention procedures to prevent damaging the equipment. Static discharge can cause components to fail completely or intermittently over time.
• Install the device in a secure area, so that only authorized personnel can access the device.

T4000 Clearance Requirements for Airflow and Hardware Maintenance
When planning the installation site, you need to allow sufficient clearance around the rack (see
):
• For the cooling system to function properly, the airflow around the chassis must be unrestricted.
NOTE: If you mount the router in a cabinet, be sure that ventilation is sufficient to prevent overheating.
• For service personnel to remove and install hardware components, there must be adequate space at the front and back of the router. At least 24 in. (61 cm) are required both in front of and behind the router. NEBS GR-63 recommends that you allow at least 30 in. (72.6 cm) behind the rack.

Signaling limitations
Radio frequency interference
Electromagnetic compatibility
If your site experiences any of the following problems, consult experts in electrical surge suppression and shielding:
•
•
•
Improperly installed wires cause radio frequency interference (RFI).
Damage from lightning strikes occurs when wires exceed recommended distances or pass between buildings.
Electromagnetic pulses (EMPs) caused by lightning damage unshielded conductors and electronic devices.
To reduce or eliminate RFI from your site wiring, do the following:
•
•
Use a twisted-pair cable with a good distribution of grounding conductors.
If you must exceed the recommended distances, use a high-quality twisted-pair cable with one ground conductor for each data signal when applicable.
If your site is susceptible to problems with electromagnetic compatibility (EMC), particularly from lightning or radio transmitters, seek expert advice.
Some of the problems caused by strong sources of electromagnetic interference (EMI) are:
•
•
Destruction of the signal drivers and receivers in the device
Electrical hazards as a result of power surges conducted over the lines into the equipment

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
.
Copyright © 2018, Juniper Networks, Inc.
93
T4000 Core Router Hardware Guide
For open-frame racks, center-mounting is preferable to front-mounting because the more even distribution of weight provides greater stability.
The router is designed for installation in a 19-in. rack as defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310-D) published by the Electronics
Components Industry Association ( http://www.ecianow.org/ ).
With the use of adapters, the router can fit into a 600-mm-wide rack, as defined in the four-part Equipment Engineering (EE); European Telecommunications Standard for
Equipment Practice (document numbers ETS 300 119-1 through 119-4) published by the
European Telecommunications Standards Institute ( http://www.etsi.org
). Use approved wing devices to narrow the opening between the rails.
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).
94 Copyright © 2018, Juniper Networks, Inc.
Figure 28: Typical Open-Frame Rack
Chapter 9: Planning and Preparing the Site
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.

• Current requirement adjustment for fans running at full speed (high temperature environment or cooling component failure):
Calculated system current (X) – Cooling (normal) + Cooling (full speed) =
X A – 6.7 A + 22 A = X A + 15.3 A
• Input current from a DC source other than –48 VDC (based on maximum configuration):
(–54 VDC input) x (input current X) = (–48 VDC) x (input current Y)
54 x X = 48 x 94.1 A
X = 48 x 94.1 A/54 = 83.6 A

For each power supply, we recommend that you provision at least 56 A @ –48 VDC per input. Doing so enables you to operate the router in any configuration without upgrading the power infrastructure. Although Input 0 in the DC power supply requires less power, we recommend provisioning the same amount of power for each input to avoid the possibility of connecting the lower-powered DC cable to Input 1 through Input 5.
Circuit breaker current rating of 100 A per feed maximum shall be incorporated external to the equipment. The voltage rating of this breaker shall be 80 V minimum. For each power supply input, use a facility circuit breaker rated for 100 A (–48 VDC) maximum or as required by local code. You must provision a circuit breaker for each DC power supply input rated for at least 125% of the continuous current that the system draws at –48 VDC.

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
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.

Understanding Fiber-Optic Cable Signal Loss, Attenuation, and Dispersion
This topic describes signal loss, attenuation, and dispersion in fiber-optic cable.

Signal Loss in Multimode and Single-Mode Fiber-Optic Cable on page 109
•
Attenuation and Dispersion in Fiber-Optic Cable on page 109
Signal Loss in Multimode and Single-Mode Fiber-Optic Cable
Multimode fiber is large enough in diameter to allow rays of light to reflect internally
(bounce off the walls of the fiber). Interfaces with multimode optics typically use LEDs as light sources. However, LEDs are not coherent sources. They spray varying wavelengths of light into the multimode fiber, which reflects the light at different angles. Light rays travel in jagged lines through a multimode fiber, causing signal dispersion. When light traveling in the fiber core radiates into the fiber cladding, higher-order mode loss results.
Together these factors limit the transmission distance of multimode fiber compared with single-mode fiber.
Single-mode fiber is so small in diameter that rays of light can reflect internally through one layer only. Interfaces with single-mode optics use lasers as light sources. Lasers generate a single wavelength of light, which travels in a straight line through the single-mode fiber. Compared with multimode fiber, single-mode fiber has higher bandwidth and can carry signals for longer distances.
Exceeding the maximum transmission distances can result in significant signal loss, which causes unreliable transmission.
Attenuation and Dispersion in Fiber-Optic Cable
Correct functioning of an optical data link depends on modulated light reaching the receiver with enough power to be demodulated correctly.
Attenuation is the reduction in power of the light signal as it is transmitted. Attenuation is caused by passive media components, such as cables, cable splices, and connectors. Although attenuation is significantly lower for optical fiber than for other media, it still occurs in both multimode

109
T4000 Core Router Hardware Guide and single-mode transmission. An efficient optical data link must have enough light available to overcome attenuation.
Dispersion is the spreading of the signal over time. The following two types of dispersion can affect an optical data link:
• Chromatic dispersion—Spreading of the signal over time resulting from the different speeds of light rays.
• Modal dispersion—Spreading of the signal over time resulting from the different propagation modes in the fiber.
For multimode transmission, modal dispersion, rather than chromatic dispersion or attenuation, usually limits the maximum bit rate and link length. For single-mode transmission, modal dispersion is not a factor. However, at higher bit rates and over longer distances, chromatic dispersion rather than modal dispersion limits maximum link length.
An efficient optical data link must have enough light to exceed the minimum power that the receiver requires to operate within its specifications. In addition, the total dispersion must be less than the limits specified for the type of link in Telcordia Technologies document GR-253-CORE (Section 4.3) and International Telecommunications Union
(ITU) document G.957.
When chromatic dispersion is at the maximum allowed, its effect can be considered as a power penalty in the power budget. The optical power budget must allow for the sum of component attenuation, power penalties (including those from dispersion), and a safety margin for unexpected losses.
Calculating Power Budget and Power Margin for Fiber-Optic Cables
Use the information in this topic and the specifications for your optical interface to calculate the power budget and power margin for fiber-optic cables.
TIP: You can use the Hardware Compatibility Tool to find information about the pluggable transceivers supported on your Juniper Networks device.
To calculate the power budget and power margin, perform the following tasks:
1.

2.
Calculating Power Margin for Fiber-Optic Cable on page 111
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

Installing the T4000 Mounting Hardware for an Open-Frame Rack
In an open-frame rack, center-mounting is generally preferable to front-mounting because the more even distribution of weight provides greater stability. If you center-mount the chassis, you use the center-mounting brackets attached to the chassis. If you front-mount the chassis, you use the front-mounting flanges, and must remove the center-mounting brackets.

T4000 Core Router Hardware Guide
To mount the chassis in the rack or cabinet using a lift (see
):
1.
If you are installing the router in an open-frame rack, ensure that the rack is in its permanent location and is secured to the building. Ensure that the installation site allows adequate clearance for both airflow and maintenance. For details, see
Clearance Requirements for Airflow and Hardware Maintenance” on page 91 .
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.
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.

CAUTION: If you are installing two routers in one rack, install the lower one first. Installing a router in the upper position in a rack or cabinet requires a lift.
160 Copyright © 2018, Juniper Networks, Inc.
Chapter 19: Installing the Router into a Rack Without a Mechanical Lift
CAUTION: Before front-mounting the router in a rack, have a qualified technician verify that the rack is strong enough to support the router's weight and is adequately supported at the installation site.
CAUTION: Lifting the chassis and mounting it in a rack requires four people.
1.
For open-frame racks, ensure that the rack is in its permanent location and is secured to the building.
2.
Ensure that the installation site allows adequate clearance for both airflow and maintenance.
3.
Attach the installation handle by tightening the captive screws of the handle into the holes previously occupied by the captive screws of the power supplies (see
Figure 51 on page 161 ). Tighten the screws, using a Phillips (+) screwdriver, number 2.
Figure 51: Attaching the Installation Handle
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.
4.
Position the router in front of the rack or cabinet, centering it in front of the mounting shelves. Use a pallet jack if one is available.
5.
With two people in the front and two people in the back, hold onto the bottom of the chassis, and carefully lift it onto the mounting shelves.
Copyright © 2018, Juniper Networks, Inc.
161
T4000 Core 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.

Chapter 21: Connecting the Router to External Devices
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 67 on page 184 , which shows a fiber-optic PIC):
1.
Have ready a length of the type of cable used by the PIC. For cable specifications, see
Determining Transceiver Support and Specifications for M Series and T Series Routers in the T4000 Core Router Interface Module Reference .
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 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 105 .

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 (terminal jumpers might also be referred to as bus bars). 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
and
Figure 83 on page 203 . Do not connect
two DC power cables using a terminal jumper to two inputs as shown in
Figure 79 on page 198 . 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.

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.
• 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.
• Other FRUs require that you power off the router or backup Routing Engine.
NOTE: Before you remove a Control Board or Routing Engine, you must take the host subsystem offline.

Taking the T4000 Host Subsystem Offline
Before you replace a control board or Routing Engine,, you must take the host subsystem offline. The host subsystem is taken offline and brought online as a unit. Normally, if two host subsystems are installed in the router, RE0 functions as the master and RE1 functions as the backup.
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.
explains the effect of taking the host subsystem offline.

Table 79: Effect of Taking the Host Subsystem Offline

Subsystem Effect of taking the Host Subsystem Offline
Nonredundant host subsystem
The router shuts down.
Backup host subsystem
Master host subsystem
The functioning of the router is not interrupted. The backup host subsystem is hot-removable and hot-insertable.
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.

Replacing a T4000 LCC-CB
The router can have up to two LCC-CBs. They are located in the upper rear of the chassis in the slots marked CB0 and CB1 . Each LCC-CB weighs approximately 5 lb (2.3 kg).
CAUTION: Before you replace a control board, you must take the host subsystem offline. The backup control board is hot-removable and hot-insertable. If the control board to be replaced is associated with the
Routing Engine currently functioning as the master Routing Engine, switch the master to the backup before removing the control board. If there is only one host subsystem, taking the host subsystem offline shuts down 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.
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).

295
T4000 Core Router Hardware Guide 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.
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.
296 Copyright © 2018, Juniper Networks, Inc.
Chapter 30: Replacing Line Card Components
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.

15.
Simultaneously turn both ejector handles clockwise until you cannot turn them farther.
16.
If any of the PICs on the FPC connect to fiber-optic cable, remove the rubber safety cap from each transceiver and cable.
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.
17.
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.

7.
Remove the clear plastic cover protecting the terminal studs on the faceplate.
8.
Remove the nut and washer from each power terminal stud.
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.
9.
Attach the lugs on the DC source power cables to the terminal studs.
a.
Attach the negative (–) DC source power cable lug to the –48V (input) terminal.
b.
Attach the positive (+) DC source power cable lug to the RTN (return) terminal.
Secure the cable lugs to the terminal studs, first with a washer, then with a nut (see
Figure 127 on page 311 ). Use a 7/16-in. (11 mm) nut driver to tighten the nut. Apply
between 23 lb-in. (2.6 Nm) and 25 lb-in. (2.8 Nm) of torque to each nut.
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).

Replacing a T4000 TXP-LCC-3D SIB
Five SIBs are installed in the router. The SIBs are located in the rear of the chassis in the slots marked SIB0 through SIB4 .
Each TXP-LCC-3D SIB weighs approximately 9.4 lb (4.2 kg). The TXP-LCC-3D SIBs are connected to the TXP-F13-3D SIBs in a TX Matrix Plus router.
TXP-LCC-3D SIBs in active data switching planes are hot-pluggable. TXP-LCC-3D SIBs in a spare data switching planes are hot-insertable and hot-removable. When you remove a TXP-LCC-3D SIB in a spare switching plane, traffic forwarding continues without any degradation as long as the other four switching planes remain online. However, removing a TXP-LCC-3D SIB in an active switching plane might cause performance degradation in that switching plane. To avoid performance degradation, you can take the switching plane offline before you remove a TXP-LCC-3D SIB. For more information, see the TX
Matrix Plus Router Hardware Guide .

Routine Maintenance Procedures for the T4000 Router
Purpose For optimum router performance, perform preventive maintenance procedures.
Action On a regular basis:
• Inspect the installation site for moisture, loose wires or cables, and excessive dust.
Make sure that airflow is unobstructed around the router and into the air intake vents.
• Check the status-reporting devices on the craft interface: system alarms, LEDs, and
LCD.
• Inspect the air filters at the bottom front and left rear of the router. Do not run the router for more than a few minutes without the air filters in place.
Check the air filters regularly for dust and debris. As a general guideline, we recommended that you replace the filter elements every 6 months for routers operating in a typical environment. The filter elements degrade over time, and replacement intervals will vary by operating environment.

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

T4000 Troubleshooting Resources Overview
To troubleshoot a T4000 router, you use the Junos OS command-line interface (CLI),
LCD, alarms, devices connected to the alarm relay contacts, and LEDs on both the components and craft interface.
• LEDs—When the Routing Engine detects an alarm condition, it lights the red or yellow alarm LED on the craft interface as appropriate. In addition, you can also use the component-specific LEDs on the craft interface and on the faceplate of a component to troubleshoot the router.
• LCD—When a red or yellow alarm occurs, the cause of the alarm messages is displayed on the craft interface LCD. Use the CLI to display more information about the alarm.
• Alarm devices connected to the alarm relay contact—When a red or yellow alarm occurs, it trips the corresponding alarm relay contact.
• CLI—The CLI is the primary tool for controlling and troubleshooting hardware, Junos
OS, routing protocols, and network connectivity. CLI commands display information from routing tables, information specific to routing protocols, and information about network connectivity derived from the ping and traceroute utilities. For information

Troubleshooting the T4000 Cooling System
Problem Description:
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.

Troubleshooting the T4000 Power System
Problem Description:
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.

•
lists alarms for the power system, including the solution.
•
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
). 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
.
3.
Check the LEDs on each six-input DC power supply faceplate. See
.
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 375
.

The input is not connected, not receiving voltage or is under –40 V.
•
•
Verify that the customer site circuit breakers are switched on. If the customer site circuit breakers are off, switch them on.
Verify that the input is receiving power within the supported voltage range.
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 power switch on the power supply faceplate is off, the power supply is not functioning normally, or the input voltage is not present or is under –40 V.
Verify that the customer site circuit breakers are switched on, and that the input is receiving power within the supported voltage range.
•
•
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.

Fire Safety Requirements

Fire Safety Requirements on page 399
Fire Safety Requirements
In the event of a fire emergency, the safety of people is the primary concern. You should establish procedures for protecting people in the event of a fire emergency, provide safety training, and properly provision fire-control equipment and fire extinguishers.
In addition, you should establish procedures to protect your equipment in the event of 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 all local fire, safety, and electrical codes and ordinances be observed when you install and operate your equipment.
Fire Suppression
In the event of an electrical hazard or an electrical fire, you should 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 and Halotron™, are most effective for suppressing electrical fires. Type C fire extinguishers displace 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, you should use this type of inert oxygen displacement extinguisher instead of an extinguisher that leaves residues on equipment.
Do not use multipurpose Type ABC chemical fire extinguishers (dry chemical fire extinguishers). The primary ingredient in these fire extinguishers is monoammonium phosphate, which is very sticky and difficult to clean. In addition, in the presence of 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 © 2018, Juniper Networks, Inc.
399
T4000 Core 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.

Prevention of Electrostatic Discharge Damage
Device components that are shipped in antistatic bags 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 when you are handling components that are subject to
ESD damage, and make sure that it is in direct contact with your skin.
If a grounding strap is not available, hold the component in its antistatic bag (see
) in one hand and touch the exposed, bare metal of the device with the other hand immediately before inserting the component into the device.
WARNING: For safety, periodically check the resistance value of the ESD grounding strap. The measurement must be in the range 1 through
10 Mohms.
• When handling any component that is subject to ESD damage and that is removed from the device, make sure the equipment end of your ESD wrist strap is attached to the ESD point on the chassis.
If no grounding strap is available, touch the exposed, bare metal of the device to ground yourself before handling the component.
• Avoid contact between the component that is subject to ESD damage and your clothing.
ESD voltages emitted from clothing can damage components.
• When removing or installing a component that is subject to ESD damage, always place it component-side up on an antistatic surface, in an antistatic card rack, or in an antistatic bag (see
). If you are returning a component, place it in an antistatic bag before packing it.

T4000 DC Power Electrical Safety Guidelines
The following electrical safety guidelines apply to a DC-powered router:
• Incorporate an easily accessible disconnect device into the facility wiring. In the United
States and Canada, the –48 VDC facility should be equipped with a circuit breaker rated a minimum of 125% of the power provisioned for the input in accordance with the National Electrical Code in the US and the Canadian Electrical Code in Canada.
WARNING: 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.
424 Copyright © 2018, Juniper Networks, Inc.
Chapter 45: Electrical Safety Guidelines and Warnings
• 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.
• 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.

DC Power Wiring Terminations Warning
WARNING: When stranded wiring is required, use approved wiring terminations, such as closed-loop or spade-type with upturned lugs. These terminations must be the appropriate size for the wires and must clamp both the insulation and conductor.
Waarschuwing Wanneer geslagen bedrading vereist is, dient u bedrading te gebruiken die voorzien is van goedgekeurde aansluitingspunten, zoals het gesloten-lus type of het grijperschop type waarbij de aansluitpunten omhoog wijzen. Deze aansluitpunten dienen de juiste maat voor de draden te hebben en dienen zowel de isolatie als de geleider vast te klemmen.
Varoitus Jos säikeellinen johdin on tarpeen, käytä hyväksyttyä johdinliitäntää, esimerkiksi suljettua silmukkaa tai kourumaista liitäntää, jossa on ylöspäin käännetyt kiinnityskorvat. Tällaisten liitäntöjen tulee olla kooltaan johtimiin sopivia ja niiden tulee puristaa yhteen sekä eristeen että johdinosan.
Attention Quand des fils torsadés sont nécessaires, utiliser des douilles terminales homologuées telles que celles à circuit fermé ou du type à plage ouverte avec cosses rebroussées. Ces douilles terminales doivent être de la taille qui convient aux fils et doivent être refermées sur la gaine isolante et sur le conducteur.
Warnung Wenn Litzenverdrahtung erforderlich ist, sind zugelassene
Verdrahtungsabschlüsse, z.B. für einen geschlossenen Regelkreis oder gabelförmig, mit nach oben gerichteten Kabelschuhen zu verwenden. Diese
Abschlüsse sollten die angemessene Größe für die Drähte haben und sowohl die Isolierung als auch den Leiter festklemmen.

Chapter 45: Electrical Safety Guidelines and Warnings
Avvertenza Quando occorre usare trecce, usare connettori omologati, come quelli a occhiello o a forcella con linguette rivolte verso l'alto. I connettori devono avere la misura adatta per il cablaggio e devono serrare sia l'isolante che il conduttore.
Advarsel Hvis det er nødvendig med flertrådede ledninger, brukes godkjente ledningsavslutninger, som for eksempel lukket sløyfe eller spadetype med oppoverbøyde kabelsko. Disse avslutningene skal ha riktig størrelse i forhold til ledningene, og skal klemme sammen både isolasjonen og lederen.
Aviso Quando forem requeridas montagens de instalação eléctrica de cabo torcido, use terminações de cabo aprovadas, tais como, terminações de cabo em circuito fechado e planas com terminais de orelha voltados para cima.
Estas terminações de cabo deverão ser do tamanho apropriado para os respectivos cabos, e deverão prender simultaneamente o isolamento e o fio condutor.
¡Atención!
Cuando se necesite hilo trenzado, utilizar terminales para cables homologados, tales como las de tipo "bucle cerrado" o "espada", con las lengüetas de conexión vueltas hacia arriba. Estos terminales deberán ser del tamaño apropiado para los cables que se utilicen, y tendrán que sujetar tanto el aislante como el conductor.
Varning!
När flertrådiga ledningar krävs måste godkända ledningskontakter användas, t.ex. kabelsko av sluten eller öppen typ med uppåtvänd tapp.
Storleken på dessa kontakter måste vara avpassad till ledningarna och måste kunna hålla både isoleringen och ledaren fastklämda.
