Ethernet controller.
Statement 5
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.
You can press the power-control button on the front of the server. This starts an
orderly shutdown of the operating system, if this feature is supported by your
operating system.
Note: After turning off the server, wait at least 5 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 4
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 approximately 15 seconds for
your system to stop running. Watch for the power-on light to stop blinking.
If the system was turned on by the Wake on LAN feature, you can turn it off by
either a software routine or by the fail-safe, power-down counter.
The system environment monitor subsystem can turn off the server.
