Front and Top Covers
CAUTION Do not operate the server without the front and top covers in place. Operation of the server
without the front and top covers in place makes the server susceptible to electromagnetic
interference (EMI) and overheating problems that result in system failure.
Observe all electrostatic discharge (ESD) safety precautions before attempting this procedure.
Failure to follow ESD safety precautions can result in damage to the server.
NOTE When the front or top cover is removed, the chassis fan units increase to high speed to assist
cooling. When the top cover is replaced at the end of the operation, the chassis fans return to
normal speed.
Removing the Front Cover
CAUTION Power the server off before removing the front cover. All components accessible behind the front
cover are cold-swappable and require power to be off.
To remove the front cover, follow these steps:
Step 1. If rack-mounted, slide the server out from the rack until it stops. (See “Accessing a Rack-Mounted
Server” on page 177.)
Step 2. Remove the front bezel. (See “Removing the Front Bezel” on page 180.)
