Intel® Server Board SE7520JR2			Connectors and Jumper Blocks
FMC Signal Name	FMC	Description
	Pin
FMM_RI_BUF_N	97	Ring Indicator from the EMP serial port on the baseboard
RST_PWRGD_PS	101	Power good signal from power subsystem. In typical system, this signal is
		connected to PWR_OK signal on power supply. This signal is monitored by the
		FMM to detect a Power Supply failure
LAN_SMBALERT_N	102	Alert signal from the motherboard NIC (LOM).
ICH_SLP_S4_N	103	Power Off request from the Chipset
ICH_SMI_BUFF_N	105	SMI signal from Chipset. This signal is monitored by the FMM to detect an “SMI
		Time-out” condition. If this signal is asserted for longer than a predefined SMI
		Time-out timer, an event is logged and the FMM interrogates the chipset for
		further data, such as fatal errors.
CHPSET_ERR_ALERT_N	106	When available from chipset, indicates that a error occurred and FMM will need
		interrogate Chipset for further data, such as fatal errors. If not available, leave
		as NC.
FP_RST_BTN_N	109	Front panel Reset Button input.
ICH_RST_BTN_N	110	Passthrough of front panel Reset button to the chipset. FMM chassis control
		command will also use this.
FP_PWR_BTN_N	113	Front panel power button input.
FMM_IRQ_SMI_N	116	FMM might use this signal to generate an SMI to the system.
FMM_PRES_N	120	When FMM is present, this signal is asserted. This signal can be used to notify
		BIOS that a module is present (via routing to GPIO), as well as to control any
		logic which behaves differently when FMM is present, such as the FML mux (if
		supported), etc

7.3.2ICMB Header

A white 5-pin header (J1D1) located on the left side of the baseboard near the internal SCSI connector cutout.

Table 88: ICMB Header Pin-out (J1D1)

Pin	Signal Name	Type	Description
1	5 V standby	Power
2	Transmit	Signal	UART signals
3	Transmit Enable	Signal	UART signals
4	Receive	Signal	UART signals
5	Ground	GND

7.3.3IPMB Header

When either the “Professional” or “Advanced” management modules are installed, the yellow 3- pin IPMB connector (J3F1) can be used to access the IPMB bus.

Note: There is no IPMB bus available with standard on-board platform instrumentation.
