Removing and Replacing the Chassis Cover
Replacing the Chassis Cover
Caution Do not operate the adaptive security appliance without the chassis cover installed. The chassis cover
protects the internal components, prevents electrical shorts, and provides proper air-flow for cooling the
electronic components.
To replace the chassis cover, perform the following steps:
Step 1 Place the chassis on a secure surface with the front panel facing you.
Step 2 Hold the top panel so the tabs at the rear of the top panel are aligned with the chassis bottom.
Step 3 Lower the front of the top panel onto the chassis as shown in Figure A-11.

Step 4
Fasten the top panel with the screws you set aside earlier as shown in Figure A-12.

Step 5

Step 6 Reinstall the network interface cables.
