Use this information to turn off the server.
When you turn off the server and leave it connected to ac power, the server can respond to requests from the Integrated Management Module 2.1 (IMM2.1), 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 the server from the power source.
Some operating systems require an orderly shutdown before you turn off the server. For information about shutting down the operating system, see your operating-system documentation or help system.
