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.
