Turning on the server
Approximately 5 seconds after the server is connected to ac power, one or more
fans might start running to provide cooling while the server is connected to power
and the power-on button LED will blink quickly. Approximately 1 to 3 minutes
after the server is connected to ac power, the power-control button becomes active
(the power-on LED will blink slowly), and one or more fans might start running to
provide cooling while the server is connected to power. You can turn on the server
by pressing the power-control button.
The server can also be turned on in any of the following ways:
v If a power failure occurs while the server is turned on, the server will restart
automatically when power is restored.
v If your operating system supports the Wake on LAN feature, the Wake on LAN
feature can turn on the server.
Note: When 4 GB or more of memory (physical or logical) is installed, 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 to the service processor, 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.
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.
