ICMB Header

A white 5-pin header (J1D1) located on the left side of the baseboard near the internal SCSI
connector cutout.
7.3.3

IPMB 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.

97 Ring Indicator from the EMP serial port on the baseboard
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
102 Alert signal from the motherboard NIC (LOM).
103 Power Off request from the Chipset
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.
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.
109 Front panel Reset Button input.
110 Passthrough of front panel Reset button to the chipset. FMM chassis control
command will also use this.
113 Front panel power button input.
116 FMM might use this signal to generate an SMI to the system.
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
