Note See the appropriate sections depending on the replacement procedures you need to perform. Then, to replace the backplane cover, proceed to the following procedure.

Use the following procedure to replace the backplane cover:

Step 1 Carefully guide the backplane cover into the chassis opening over the arbiter and CI, and over the guide pins on the backplane. (See Figure 5-5.) Align the screw holes in the cover with the holes on the backplane and standoffs.

Step 2 Loosely install the 15 screws around the flange of the backplane cover. (See Figure 5-5.) Do not tighten these screws.

Step 3 Loosely install the eight standoff screws in the face of the backplane cover.

Step 4 Verify that the cover is aligned; then tighten all screws that secure the backplane cover.

Step 5 Replace the fan tray. (Follow Step 1 through Step 5 in the procedure for replacing the fan tray in the “Removing and Replacing the Cisco 7505 Fan Tray” section on page 5-5.)

Step 6 Reattach the power harness plug to the power harness receptacle. The harness plug and backplane receptacle are polarized with notches at the top of both guide tabs (top and bottom) on the plug. Ensure that the plug is fully seated in the receptacle.
