Table 3-14. Power and System Management Signal Descriptions (Continued)
	SUS_S3#	Indicates system is in Suspend to RAM state.		O 3.3VSB		PU 10k
		Active low output. Also known as "PS_ON"				3.3VSB
		and can be used to control an ATX power
		supply.
	SUS_S4#	Indicates system is in Suspend to Disk state.		O 3.3VSB		PU 10k		Not
		Active low output.				3.3VSB		supported
	SUS_S5#	Indicates system is in Soft Off state.		O 3.3VSB		PU 10k
						3.3VSB
	WAKE0#	PCI Express wake up signal.		I 3.3VSB		PU 10k
						3.3VSB
	WAKE1#	General purpose wake up signal. May be used		I 3.3VSB		PU 10k
		to implement wake-up on PS/2 keyboard or				3.3VSB
		mouse activity.
	BATLOW#	Battery low input. This signal may be driven		I 3.3VSB		PU 10k
		low by external circuitry to signal that the				3.3VSB
		system battery is low, or may be used to signal
		some other external power-management event.
	THRM#	Input from off-module temp sensor indicating		I 3.3V		PU 10k
		an over-temp situation.				3.3V
	THERMTRIP	Active low output indicating that the CPU has		O 3.3V		PU 10k
	#	entered thermal shutdown.				3.3V
	SMB_CK	System Management Bus bidirectional clock		I/O		PU 2k2
		line. Power sourced through 5V standby rail		3.3VSB		3.3VSB
		and main power rails.
	SMB_DAT#	System Management Bus bidirectional data		I/O		PU 2k2
		line. Power sourced through 5V standby rail		3.3VSB		3.3VSB
		and main power rails.
	SMB_ALERT	System Management Bus Alert – active low		I 3.3VSB		PU 10k
	#	input can be used to generate an SMI# (System				3.3VSB
		Management Interrupt) or to wake the system.
		Power sourced through 5V standby rail and
		main power rails.

	Signal		Description		I/O		PU/	Comment
							PD
	VCC_12V		Primary power input: +12V nominal. All		P
			available VCC_12V pins on the connector(s)
			shall be used.
	VCC_5V_SBY		Standby power input: +5.0V nominal. If		P
			VCC5_SBY is used, all available
			VCC_5V_SBY pins on the connector(s) shall
			be used. Only used for standby and suspend
			functions. May be left unconnected if these
			functions are not used in the system design.
