Before you turn off the blade server, shut down the operating system. 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:
v You can press the power button on the blade server (see “Blade server controls
and LEDs”). Pressing the button starts an orderly shutdown of the operating
system, if this feature is supported by the operating system.
v If the operating system stops functioning, you can press and hold the power
button for more than 4 seconds to turn off the blade server.
Attention: Pressing the button for 4 seconds forces the operating system to
shut down immediately. Data loss is possible.
v You can turn off the blade server through the advanced management module
web interface. For more information about the advanced management module
web interface, see the IBM BladeCenter Advanced Management Module: User's
Guide.
