Refer to the Cisco 7000 Hardware Installation and Maintenance publication for complete

This section describes the LED board and the top and bottom front chassis panels.
The top and bottom front chassis panels each comprise a plastic injected-molded bezel
on a metal frame. The top front panel covers the entire front chassis opening and attaches
to the bottom of the chassis frame with two captive screws (see Figure 1). The lower
section of the top front panel houses the air filter, which cleans intake air drawn in by
the blower. Three cutouts in the top of the panel contain semi-opaque black plastic
windows, through which the three system LEDs are visible when they are lit. EMI
shielding surrounds the entire outer edge of the top front panel. The shielding acts as a
spring, and compresses when you push the panel into the chassis to keep the panel fitted
tightly into the chassis opening.
The bottom front panel is vented and covers the lower area of the top front panel that
houses the air filter. The bottom front panel fits over the lower section of the top front
panel and attaches to the chassis with ball studs. You must remove the bottom front panel
before you can remove the top front panel.
You can remove the bottomD front panel while the system is operating to access or clean
the air filter, but always turn system power off before removing the top front panel.
