Server power features
When the server is connected to an ac power source but is not turned on, the
operating system does not run, and all core logic except the service processor is
shut down; however, the server can respond to requests from the service processor,
such as a remote request to turn on the server. The power-on LED flashes to
indicate that the server is connected to ac power but not turned on.
Turning on the server
Approximately 20 seconds after the server is connected to ac power, the
power-control button becomes active, and one or more fans might start running to
provide cooling while the server is connected to power. You can turn on the server
and start the operating system 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 systems-management software for an
optional Remote Supervisor Adapter II SlimLine, the systems-management
software can turn on the server.
v
If your operating system supports the Wake on LAN feature, the Wake on LAN
feature can turn on the server.
v
If an optional Remote Supervisor Adapter II SlimLine is installed in the server, the
server can be turned on from the Remote Supervisor Adapter II SlimLine user
interface.
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 optional devices.
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 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.
