The power control button on the device and/or 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.
You can start the server in several ways:
• You can turn on the server by pressing the Power Control button on the
front of the server.
Note: After you plug the power cords of your server into electrical
outlets, wait 20 seconds before pressing the Power Control button.
During this time the system-management processor is initializing
and the Power Control button does not respond.
• If the server is turned on, a power failure occurs, and unattended- start
mode is enabled in the Configuration/Setup utility program, the server
will start automatically when power is restored.
• If AC power is present, the server is off, and the wake-up feature is
enabled in the Configuration/Setup utility program, the wake-up feature
will turn on the server at the set time.
• If AC power is present, the server is off, and ring signal detect is enabled
in the Configuration/Setup utility program, you can turn on the server
by telephone input.
• The Netfinity Advanced System Management Processor also can turn on
the server.
You can turn off the server in several ways:
• You can turn off the server by pressing the Power Control button on the
front of the server. Pressing the Power Control button starts an orderly
shutdown of the operating system, if this feature is supported by your
operating system, and places the server in standby mode.
Note: After turning off the server, wait at least 5 seconds before pressing
the Power Control button to power the server on again.
• You can press and hold the Power Control button for more than 4 seconds
to cause an immediate shutdown of the server and place the server in
standby mode. You can use this feature if the operating system stalls.
• You can disconnect the server power cords from the electrical outlets to
shut off all power to the server.
Note: Wait about 15 seconds after disconnecting the power cords for
your system to stop running. Watch for the System Power light on
the operator information panel to stop blinking.
