Cold-service procedures require that you shut the server down and unplug the power cables that
connect the power supplies to the power source.
Although hot-service procedures can be performed while the server is running, you should
usually bring it to standby mode as the first step in the replacement procedure. See “Power Off
the Server (Server Power Button - Graceful)” on page 47 for instructions.
