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 from the
IMM2, 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.
