Turning off the server
CAUTION:
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.
The server can be turned off in one of the following ways:
• Turn off the server from the operating system if your operating system supports this feature. After an
orderly shutdown of the operating system, the server will turn off automatically. For instructions on how
to shut down your specific operating system, refer to the related documentation or help system for
the operating system.
• Press the power button on the front panel to start an orderly shutdown of the operating system and turn
off the server, if your operating system supports this feature.
• If your server stops responding and you cannot turn it off, press and hold the power button on the
front panel for four seconds or more. If you still cannot turn off the server, disconnect all power cords
from the server.
• The server might be turned off as an automatic response to a critical system failure.
Note: For information about your specific operating system, refer to the related documentation or help
system for the operating system.
