Turning off the server
Use this information to turn off the server.
When you turn off the server and leave it connected to input power, the server can respond to requests to the
service processor (the integrated management module), such as a remote request to turn on the server.
While the server remains connected to input 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.
