Removing and Replacing the Front Chassis Panels

Removing the Panels

6Cisco 7000 Air Filter and Chassis Blower Replacement Instructions

To access the air ﬁlter, you must remove the bottom front chassis panel. To access the

chassis interior to replace the blower, you must remove the top and bottom front chassis

panels to. Carefully follow the instructions for removing and replacing the top front

panel because you can damage or destroy the LED board or top front panel by forcing a

misaligned panel onto or off of the chassis body.

Warning:

Before accessing the chassis interior, turn all power supply switches OFF

(O) and unplug the power cord. When the power is ON (|), high current (100A) is

exposed on the backplane and around the power supply and wiring harnesses.

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.

To remove the front panels, perform the following steps:

Step 1:

Grasp the bottom edge of the bottom chassis panel.

Step 2:

Pull the bottom of the panel out about one inch, then place your ﬁngers

behind the sides of the panel and pull it off the chassis (see Figure 4).
