Turning off the blade server
When you turn off the blade server, it is still connected to power through the
BladeCenter unit. The blade server can respond to requests from the service
processor, such as a remote request to turn on the blade server. To remove all
power from the blade server, you must remove it from the BladeCenter unit.
Shut down your operating system before you turn off the blade server. See your
operating-system documentation for information about shutting down the operating
system.
The blade server can be turned off in any of the following ways:
v You can press the power-control button on the blade server (behind the control
panel door). This starts an orderly shutdown of the operating system, if this
feature is supported by your operating system.
Note: After turning off the blade server, wait at least 5 seconds before you press
the power-control button to turn on the blade server again.
v
If the operating system stops functioning, you can press and hold the
power-control button for more than 4 seconds to turn off the blade server.
v
The management module can turn off the blade server.
Note: After turning off the blade server, wait at least 30 seconds for its hard disk
drives to stop spinning before you remove the blade server from the
BladeCenter unit.
