Turning Off The Server; Connecting External Devices - Lenovo ThinkServer RD240 Hardware Maintenance Manual

Turning off the server

When you turn off the server and leave it connected to ac 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 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.

The power control button on the device and the power switch on the power supply do not turn off
