This COM2 header supports
a serial port module.
This 4-pin connector is used
to provide a cabled base-
board or front panel connec-
tion for value added features
and 3rd-party add-in cards,
such as Emergency Man-
agement cards, that provide
management features using
the IPMB.
Please connect the thermal
sensor cable to either pin
1-2 or pin 2-3 and the other
end to the device which you
wish to monitor its tempera-
ture.
CLRCMOS2 allows you to
clear the data in CMOS. To
clear CMOS, take out the
CMOS battery and short the
Clear CMOS Pad.
