Turning on or turning off the server
When the server is connected to an ac power source but is not turned on, the operating system does not
run, and all core logic except for the Integrated Management Module II (IMM2) is shut down.
However, the server can respond to requests from Integrated Management Module II (IMM2), 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 20 seconds after the server is connected to ac power, one or more fans might start running to
provide cooling and the power-on button LED starts blinking quickly. Approximately one to three minutes
after the server is connected to ac power, the power-control button becomes active and the blink of the
power-on button LED turns slow.
You can turn on the server by pressing the power-control button.
You also can turn on the server through the Wake on LAN feature if supported by the operating system. You
can send a request through the Wake on LAN feature to turn on the server remotely.
Besides, if a power failure occurs while the server is turned on, the server will restart automatically when
power is restored.
Turning off the server
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
theIntegrated Management Module II (IMM2), 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.

The power control button on the device and the power switch on the power supply do not turn off
the electrical current supplied to the device. The device also might have more than one power
cord. To remove all electrical current from the device, ensure that all power cords are disconnected
from the power source.
