When you turn off the server and leave it connected to input power, the server can respond to requests to
the service processor (the IMM), 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.

The power control button on the device do not turn off the electrical current supplied to the device.
