Replacing the CI in the Cisco 7507
The following procedures describe how to replace the CI in the Cisco 7507. Depending on your
installation, you might need to remove the Cisco 7507 from the rack in which it is installed. To
replace the CI in the Cisco 7507, you must first remove the front chassis panels.
Removing the Front Chassis Panels
You must remove the top and bottom front chassis panels to access the chassis interior to replace the
CI board.
Warning
Before working on a system that has an on/off switch, turn OFF the power and unplug
the power cord. (For a translation of this safety warning, refer to the section “Translated Safety
Warnings” on page 32.)
You must remove the bottom front panel before you can remove the top front panel. The plastic
bottom front panel is attached to the chassis with ball studs. The top front panel is attached to the
chassis with two captive screws. The EMI shielding around the outer edge of the top front panel acts
as a spring, and compresses when you push the panel into the chassis to keep the panel fitted tightly
into the chassis opening.
