Chapter 6 Maintaining Your Cisco 7507 and Cisco 7507-MX Router

Maintenance Procedures for the Cisco 7507 and Cisco 7507-MX

Use the following procedure to replace the CI:

Step 1 Attach an ESD-preventive strap (your own or the one supplied with the FRU) between you and an unpainted chassis surface.

Step 2 Position the CI in the vertical orientation shown in Figure 6-8, with the connector along the edge of the CI facing the CI backplane connector. Both CI connectors are keyed so you cannot install the CI incorrectly; however, to prevent damage to the connector pins, determine the correct connection orientation before you install the CI.

Step 3 Attach the CI edge connector to the connector on the backplane. Align the CI edge connector keys with the backplane connector keys; the CI should attach to the backplane connector with a moderate amount of force. Do not force the CI connector onto the backplane connector. It might be necessary to gently rock the connectors into place.

Step 4 Replace the top and bottom front chassis panels. (See Step 1 through step 9 in the procedure for replacing front cover panels in the “Removing and Replacing the Cisco 7507 and Cisco 7507-MX Front Chassis Panels” section on page 6-6.)

This completes the CI replacement procedure for the Cisco 7507 and Cisco 7507-MX.

Removing and Replacing the Cisco 7507 and Cisco 7507-MX LED Board

The LED board contains the three status LEDs that provide system and power supply status on the front panel. Replace the LED board only if it fails or if one of the LEDs fails.

The LED board is mounted on a horizontal plane near the top of the chassis interior. See Figure 6-8. The board slides into two brackets mounted to the front of the backplane and attaches to a connector on the backplane. Two pins in the brackets and a metal spring keep the board in place. Figure 6-10

Use the following procedure to remove the existing LED board:

Step 1 On each installed power supply, turn off the power switch and disconnect the power cable from the power source.

Step 2 Remove the front panels. (See Step 1 through Step 6 in the procedure for removing front cover panels in the “Removing and Replacing the Cisco 7507 and Cisco 7507-MX Front Chassis Panels” section on page 6-6.)

Step 3 Locate the LED board (see Figure 6-8), which is mounted on a horizontal plane in two plastic brackets.

Step 4 Two steel pins near the front of the brackets hold the board in place. Figure 6-10On each pin, place your thumb on the top of the pin and your forefinger underneath the bracket to support it; press the pins down and out of the guide holes in the board.
