NOTE
Some memory is reserved for various system resources and is unavailable to the operating system. The
amount of memory that is reserved for system resources depends on the operating system, the
configuration of the server, and the configured PCI options.
Turning off the server
When you turn off the server and leave it connected to ac power, the server can respond to
requests from the IMM, 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 it from the power source.
CAUTION
To view the error LEDs on the system board, leave the server connected to a power source.
Some operating systems require an orderly shutdown before you turn off the server. See your
operating-system documentation for information about shutting down the operating system.
Statement 5:
WARNING
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 any of the following ways:
You can 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 be turned
off automatically.
You can press the power-control button to start an orderly shutdown of the operating
system and turn off the server, if your operating system supports this feature.
If the operating system stops functioning, you can press and hold the power-control
button for more than 4 seconds to turn off the server.
