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.

Reinstalling Components
NOTE: For complete instructions on reinstalling router components after
you have installed the router without a mechanical lift, see the T640 Core
Router Hardware Guide.
1. Slide each component into the chassis evenly so that it does not become stuck or
damaged.
2. Tighten the captive screws for each component.
3. Make sure that all empty slots are covered with a blank panel before operating the
router.
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.
