Turning off the blade server

When you turn off the blade server, it is still connected to power through the BladeCenter chassis. 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 chassis.

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:

  • 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.
  • 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.
  • 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 ../com.ibm.bladecenter.advmgtmod.doc/adv_man_mod_printable_doc.html.
