Turning off the blade server
Use this information to turn 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
the operating system before you turn off the blade server. See the operating-system documentation for
information about shutting down the operating system.
The blade server can be turned off in any of the following ways:
• You can press the power-control button on the blade server (see “Blade server controls and LEDs” on
page 11). This starts an orderly shutdown of the operating system, if this feature is supported by the
operating system.
• 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.
• The management module can turn off the blade server through the Advanced-Management-Module Web
interface. For additional information, see the IBMBladeCenter Management Module User’s Guide or
go to “” on page for more information.
