Chapter 7 Maintaining Your Cisco 7513, Cisco 7513-MX, and Cisco 7576 Router

Maintenance Procedures for the Cisco 7513, Cisco 7513-MX, and Cisco 7576

Figure 7-14 Location of the CIs with Maintenance Cover Removed (Cisco 7576 shown)

Note When you view the rear of the card cage, the dual arbiter and chassis interface on the right side are used

with router A, and the dual arbiter and chassis interface on the left side are used with router B.

The following procedure assumes you have already removed the chassis cover panels and backplane

maintenance cover. If not, see the appropriate procedures in this chapter to remove these items. Replace

the CI only if it fails.

The following procedures apply to the Cisco 7513, Cisco 7513-MX, and Cisco 7576. The only difference

is that the Cisco 7576 has two CIs on the backplane, as shown in Figure 7-14. If you have a CI problem

with a Cisco 7576, determine which CI has failed, and replace only the failed CI.

Use the following procedure to remove the CI:

Step 1 Turn off the power switch on each power supply and disconnect the power cable from each power source

and power supply.

Step 2 Attach an ESD-preventive strap between you and an unpainted chassis surface.

Step 3 The CI is held in place by a connector, which is connected to the backplane, and four screws. Use a

number 1 Phillips screwdriver to remove the four screws.

Caution Access to the CI is partially blocked by a chassis panel. (See Figure 7-13 for the Cisco 7513 and Cisco

7513-MX and Figure 7-14 for the Cisco 7576.) Two of the screws are below this panel, and two are above

it. To avoid damaging CI components, do not hit the CI against the chassis panel.
