T640 Core Router Quick Start

T640 Quick Start Description
This Quick Start contains information you need to install and configure the router quickly.
For complete installation instructions, see the T640 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 47. For a complete list of warnings for this router, including
translations, see the T640 Core Router Hardware Guide at
http://www.juniper.net/techpubs/hardware/.
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 also contains an accessory
box and a Quick Start (this document).

T640 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 T640 Core Router
Hardware Guide.
•Rack-Mounting Requirements on page 4
•Tools Required to Unpack and Prepare the T640 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 565 lb (256.3 kg). If you mount two routers in one rack, it must be capable
of supporting a combined weight of over 1100 lb (499 kg).
•For service personnel to remove and install hardware components, there must be
adequate space at the front and back of the router. Allow at least 24 in. (61.0 cm) both
in front of and behind the router.
•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.

Figure 1: Rack Clearances and Router Dimensions
Tools Required to Unpack and Prepare the T640 Router for Installation
•A mechanical lift—recommended
•1/2-in. or 13-mm open-end or socket wrench to remove bracket bolts from the shipping
pallet
•Phillips screwdrivers, numbers 1 and 2
•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
•AC-powered router:
•Phillips (+) screwdriver, number 2 to access the metal AC wiring compartment

•1/4-in. slotted screwdriver to attach the ground wire and input terminal wires of the
AC power cord.
•Wire cutters
•Cage nuts, if needed for your rack or cabinet
•Electrostatic discharge wrist strap
•Antistatic mat
•Blank panels to cover any slots not occupied by a component

To install the mounting hardware for a four-post rack or cabinet:
•Installing Cage Nuts, If Needed on page 8
•Installing the Large Mounting Shelf and Spacer Bars on page 8
•Installing the Small Mounting Shelf on page 9
•Removing the Center-Mounting Brackets on page 9
Installing Cage Nuts, If Needed
For racks without threaded holes, you must install cage nuts in the locations specified in
Table 1 on page 7:
•On each front rack rail, install cage nuts for the large shelf and spacer bars.
•On each rear rack rail, install cage nuts for the small shelf.
Installing the Large Mounting Shelf and Spacer Bars
1. On the front side of each front rail, partially insert a mounting screw into the lowest
hole specified in Table 1 on page 7 for the large shelf.
2. Install the large shelf on the front side of the front rack rails. Rest the bottom slot in
each flange on one of the mounting screws.
3. Tighten all the screws completely.
4. Place one spacer bar over a flange of the large shelf.
5. Partially insert a mounting screw into each of the nonthreaded holes in the recesses
of the spacer bar.

6. Repeat Step 4 and Step 5 for the other spacer bar.
7. Tighten all the screws completely.
Installing the Small Mounting Shelf
The small shelf installs on the back of the rear rails, extending toward the center of the
rack. See Table 1 on page 7.
1. Partially insert a mounting screw into the lowest hole specified in Table 1 on page 7.
2. Install the small shelf on the back of the rear rack rails. Rest the bottom slot on each
flange on one of the mounting screws.
3. Partially insert screws into the open holes in the ears of the small shelf.
4. Tighten all the screws completely.
Removing the Center-Mounting Brackets
The router is shipped with a spacer bar attached to the back of each front-mounting
flange, and two center-mounting brackets attached to the chassis. Remove the center
mounting brackets from the chassis by loosening the screws at the top and bottom of
each bracket.
Installing the Mounting Hardware in an Open-Frame Rack
To install the mounting hardware for an open frame rack:
•Front-mount: Attach the large mounting shelf on the back of the rails. Remove the
center-mounting brackets from the chassis.
•Center mount: Attach the large mounting shelf on the back of the rails. You do not
have to remove the center-mounting brackets from the chassis.
The small mounting shelf is not needed for open-frame racks.Table 2 on page 10 specifies
the holes in which you insert mounting screws, and cage nuts if needed.
