		v When the server is turned on, air is flowing from the fan grille. If there is no

		shut down.

		Timer in the UEFI Setup Utility program to see the POST watchdog setting),
		make sure that sufficient time is allowed in the watchdog timeout value

		“POST” on page 21.
	2. If the reset occurs after the operating system starts, disable any automatic
		server restart (ASR) utilities or ASR devices that may be installed.
		Note: ASR utilities operate as operating-system utilities and are related to the
		IPMI device driver. If the reset continues to occur after the operating system
		starts, the operating system might have a problem; see “Software problems” on
		page 64.
	3. If neither condition applies, check the system-error log or IMM system event
		log (see “POST” on page 21).
