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 7-13for the Cisco 7513 and Cisco 7513-MX and Figure 7-14for 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.
