This 4-pin connector is used
to provide a cabled base-board
or front panel connection for
value added features and 3rd-
party add-in cards, such as
Emergency Management cards,
t h a t p r o v i d e m a n a g e m e n t
features using the IPMB.
he header is used for the SM
BUS devices.
his COM2 header supports a
serial port module.
CLRCMOS2 allows you to
clear the data in CMOS. To
clear CMOS, take out the
CMOS battery and short the
