Server power features
When the server is connected to a suitable input power source but is not turned
on, the operating system does not run, and all core logic except for the service
processor (the integrated management module) is shut down; however, the server
can respond to requests to the service processor, such as a remote request to turn
on the server. The power-on LED flashes and indicates that the server is connected
to input power but is not turned on.
Turning on the server
Approximately 5 seconds after the server is connected to input power, one or more
fans might start running and the power-on LED flashes quickly. Approximately 10
seconds after the server is connected to input power, the power-on button becomes
active. After the power-on button becomes active, the power-on LED flashes
slowly. You can turn on the server by pressing the power-on button.
If a power failure occurs while the server is turned on, the server will restart
automatically when power is restored.
Note: To disable this feature in the Setup utility (see “Using the Setup utility” on
page 127), select System Settings → Integrated Management Module → Power
Restore Policy.
Turning off the server
When you turn off the server and leave it connected to input power, the server can
respond to requests to the service processor (the integrated management module),
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.
