Warning

Before working on a system that has an on/off switch, turnOFF the power and unplug the power cord.

Removing and Replacing the Cisco 7505 Cover Panel

The two captive slotted screws are the only fasteners on the cover panel. Five shallow tabs at the bottom

edge of the panel fit into slots at the base of the chassis opening. The tabs act as a pivot point for pulling

the top of the panel away from the chassis opening, and as guides to align the panel when replacing it.

If the chassis cover does not seal the end of the chassis, the flow of cooling air inside the chassis can be

misrouted, which can result in an overtemperature condition.

Warning

Before working on the chassis or near power supplies, disconnect the power cable on AC units or

disconnect the power at the circuit breaker on DC units.
