T4000 Core Router Quick Start

Quick Start Description
This Quick Start contains information you need to install and configure the router quickly.
For complete installation instructions, see the T4000 Core Router Hardware Guide at
http://www.juniper.net/techpubs/hardware/.
WARNING: This Quick Start contains a summary of safety warnings in “Safety
Warnings” on page 35. For a complete list of warnings for this router, including
translations, see the T4000 Core Router Hardware Guide at
http://www.juniper.net/techpubs/hardware/.
The router is a complete routing system that provides Gigabit Ethernet, SONET/SDH,
and other high-speed interfaces for large networks and network applications. The router
supports up to eight Flexible PIC Concentrators (FPCs). In a standalone configuration,
the router’s maximum aggregate throughput is up to 2000 gigabits per second (Gbps),
full duplex (4000 Gbps of any-to-any, nonblocking, half-duplex) switching.
The router is shipped in a wooden crate. A wooden pallet forms the base of the crate.
The router chassis is bolted to this pallet. The shipping crate contains:
•One accessory box (the box to which this Quick Start is taped)
•One Juniper Networks router
•One Quick Start (this document)

Quick Start Description

Step 1: Preparing the Site
Before installing the router, make sure that the site meets all the power, environmental,
and clearance requirements. See the site preparation guidelines in the T4000 Core Router
Hardware Guide.
•Rack-Mounting Requirements on page 4
•Tools Required to Unpack and Prepare the T4000 Router for Installation on page 5
Rack-Mounting Requirements
•You can install the router in many types of racks, including a four-post rack or cabinet
or an open-frame rack.
•The rack rails must be spaced widely enough to accommodate the router chassis's
external dimensions: 37.45 in. (95.6 cm) high, 31 in. (78.7 cm) deep, and 17.43 in. (44.3
cm) wide. The mounting brackets extend the width to fit into standard 19-in. (48.3
cm) racks.
•The rack must be strong enough to support the weight of the fully configured router,
up to about 663.6 lb (301.0 kg). If you mount two routers in one rack, it must be capable
of supporting a combined weight of over 1327.2 lb (602.0 kg)
•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. (61.0 cm) both in
front of and behind the rack or cabinet is required. However, NEBS GR-63 recommends
at least 30 in. in front of the rack or cabinet. See Figure 1 on page 5.
•The rack or cabinet must have an adequate supply of cooling air.
•In a closed cabinet, there must be a minimum of 6 in. (15.2 cm) of unobstructed airflow
behind the router, or airflow baffles must be installed to prevent recirculation of hot
air and overheating.
•If the router is the only unit in the rack, mount it at the bottom.
•When mounting the router in a partially filled rack, load the rack from the bottom to
the top, with the heaviest component at the bottom of the rack.

Step 4: Connecting the Grounding Cable
You ground the router by connecting a grounding cable to earth ground and then attaching
it to the chassis grounding points with two screws. You must provide the grounding cable
(a cable lug is supplied with the router). To connect the grounding cable (see Figure 8
on page 19):
1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
the strap to an approved site ESD grounding point. See the instructions for your site.
2. Make sure that grounding surfaces are clean and brought to a bright finish before
grounding connections are made.
3. Connect the grounding cable to a proper earth ground.
4. Verify that a licensed electrician has attached the cable lug provided with the router
to the grounding cable.
5. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
the strap to one of the ESD points on the chassis.
6. Place the grounding cable lug over the grounding points. The left pair is sized for M6
screws, and the right pair is sized for UNC 1/4-20 screws.
7. Secure the grounding cable lug to the grounding points, first with the washers, then
with the screws.
8. Verify that the grounding cabling is correct, that the grounding cable does not touch
or block access to router components, and that it does not drape where people could
trip on it.

Step 5: Connecting External Devices and PIC Cables
To connect external devices and PIC cables, perform the following procedures:
•Connecting to a Console or Auxiliary Device on page 20
•Connecting the PIC Cables on page 21
•Connecting to a Network for Out-of-Band Management on page 22
Connecting to a Console or Auxiliary Device
To use a system console to configure and manage the Routing Engine, connect it to the
appropriate CONSOLE port on the CIP. To use a laptop, modem, or other auxiliary device,
connect it to the appropriate AUXILIARY port on the CIP. Both ports accept an RS-232
(EIA-232) serial cable with a DB-9 female connector. One DB-9/DB-9 cable is provided
with the router. To connect a device to the CONSOLE port, and another device to the
AUXILIARY port, you must supply another cable.
To connect a management console or auxiliary device:
1. Turn off the power to the console or auxiliary device.
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. Connect one end (shown in Figure 9 on page 21) of a serial cable with a DB-9 female
connector to the appropriate CONSOLE or AUXILIARY port (see Figure 10 on page 21).
The ports labeled HOST 0 connect to the Routing Engine in the upper Routing Engine
slot (RE0), and the ports labeled HOST 1 connect to the Routing Engine in the lower
Routing Engine slot (RE1).
NOTE:
For console devices, configure the serial port to the following values:
•Baud rate—9600
•Parity—N
•Data bits—8
•Stop bits—1
•Flow control—none
4. Using a 2.5-mm flat-blade screwdriver, tighten the screws on the connector.
5. Attach the other end of the cable to the console or auxiliary device.
