• If your operating system supports the system-management software, the system-
management software can turn on the server.
• If your operating system supports the Wake on LAN feature, the Wake on LAN
feature will turn on the server at the set time.
Note: For more detailed information about the Wake on LAN feature, refer to the
documentation that comes with the Wake on LAN adapter and cables.
Turning off the server
Turning off the server refers to the act of disconnecting the server from the power
source.
You can turn off the server in any of the following ways:
• You can press the power-control button on the front of the server. If this feature is
supported by your operating system, this starts an orderly shutdown of the
operating system, and places the server in standby mode.
Note: After turning off the server, wait at least five seconds before you press the
power-control button to turn on the server again.
• You might need to press and hold the power-control button for more than four
seconds to cause an immediate shutdown of the server and to force the power off.
You can use this feature if the operating system stops functioning.
• You can disconnect the server power cords from the electrical outlets to shut off
all power to the server.
Note:
After disconnecting the power cords, wait about 15 seconds for your
system to stop running. Watch for the power-on light on the information
panel to stop blinking.
