Removing and Replacing Internal Components
To upgrade, remove, or replace most server components, you must first shut down the server,
and remove the top metal cover.
WARNING! Do not remove the server covers without first powering the server off and
unplugging the power cord from the outlet or power protection device unless you are replacing
a hot-swappable fan.
When the server is running, you must replace the top metal cover within 30 minutes to prevent
components from overheating. If the top metal cover is not replaced within 30 minutes, the server
automatically shuts down. If the server shuts down, always replace the covers before turning
the server back on.
