(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 to indicate that the server is connected to ac
power but is not turned on.
Turning on the server
Approximately 5 seconds after the server is connected to ac power, one or more
fans might start running to provide cooling while the server is connected to power
