	This will allow the blade server to restart using Wake on LAN even if the Linux
	shutdown is incomplete and the blade server does not turn off.
	Forcing a blade server to turn off
	Complete the following steps to turn off a blade server after an incomplete Linux
	shutdown:
	1. Manually press the power-control button on the front of the blade server (behind
	the control panel door) to turn off the blade server. Turning off the blade server in
	this way is considered an improper shutdown by the Wake on LAN feature, and
	the Wake on LAN feature will not restart the blade server.
	2. Unlatch and slide the blade server partially out of the BladeCenter; then, reinstall
	it to reset the blade server power state and re-enable its previously programmed
	Wake on LAN capability.
