Turning Off The Server - IBM System x3550 M4 Installation And Service Manual

Turning off the server

Use this information to turn off the server.
When you turn off the server and leave it connected to power, the server can
respond to requests to the service processor, such as a remote request to turn on
the server. While the server remains connected to power, one or more fans might
continue to run. To remove all power from the server, you must disconnect it from
the power source.
Some operating systems require an orderly shutdown before you turn off the
server. See your operating-system documentation for information about shutting
down the operating system.
