The Service Processor can be enabled to recover from the loss of ac power (see

Enable/Disable Unattended Power-On Mode		in	the SYSTEM POWER	CONTROL
MENU). When ac power is restored,	the system returns to the then current
power state at the time ac loss	occurred. For example,			if the system	was
powered-on when ac loss occurred,	it	reboots/restarts when power is restored. If
the system was powered-off when	ac	loss	occurred, it	remains off when	power is
restored.
