When you turn off the server and leave it connected to ac power, the server can respond to requests from
Integrated Management Module II (IMM2), such as a remote request to turn on the server. While the server
remains connected to ac 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.
