Standby mode

is in Standby mode. When the server is in Standby mode, the operating system is
not running, and all core logic except for the service processor is shut down. The
power-on LED flashes to indicate that the server is in Standby mode. The server
can respond to requests from the service processor, such as a remote request to
turn on the server.
To put the server into Standby mode when the server is turned on, shut down the
operating system (see your operating-system documentation), and press the
power-control button.
You can also put the server into Standby mode through a request from the service
processor.
