memory is reserved for various system resources and is unavailable to the
operating system. The amount of memory that is reserved for system
resources depends on the operating system, the configuration of the server,
and the configured PCI options.
Turning off the server
When you turn off the server and leave it connected to 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 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.
