WARNING: To reduce the risk of personal injury from hot surfaces, allow the drives and the
internal system components to cool before touching them.
CAUTION: To prevent damage to electrical components, take the appropriate anti-static
precautions before beginning any installation, removal, or replacement procedure. Improper
grounding can cause electrostatic discharge.
CAUTION: To prevent improper cooling and thermal damage, do not operate the server unless
all bays are populated with either a component or a blank.
To remove the component:
1. If a full-length expansion board is installed in the server, do the following:
a. Power down the server (on page 27).
b. Disconnect each power cord from the power source.
c. Disconnect each power cord from the server.
