Table 8.	P30 Signal Descriptions
	Pin	Signal	Comments
	A1	Logic_GND	Logic ground connection (long contact); provides return path for power and signal
			connections.
	A2	Shelf_GND	Shelf ground connection (long contact); provides safety ground contact between
			SBC and RTM.
	B1	Logic_GND	Logic ground connection (long contact); see above.
	B2	+3.3V_MP	Management power (long contact); provides up to 100mA to power management
			system on RTM. Used exclusively for management power.
	C1	IPMI_Sclk	IPMB/I2C clock signal (medium contact)
	C2	IPMI_Sdata	IPMB/ I2C data signal (medium contact); This signal is connected to the on board
			ADM1026 for temperature and voltage monitoring on the RTM.
	D1	12V	12V RTM payload power (short contact); provides up to 420mA to power active
			devices (other than management system) on RTM. See additional requirements
	D2	12V
			below.
			Presence Signal, active low (short contact); the RTM connects this signal to
	E1	PS1#	Logic_GND through a 100 Ohm resistor (to facilitate manufacturing test). The Front
			Board reads this signal to understand if an RTM is fully inserted.
	E2	ENABLE#	Module enable signal, active low (short contact); the Front Board sets this signal high
			to reset the RMC/RMD.
