CLRMOS1 allows you to clear
the data in CMOS. To clear
CMOS, take out the CMOS
battery and short the Clear
CMOS Pad.
PSU SMBus monitors the
status of the power supply, fan
and system temperature.
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.
The header is used for the SM
BUS devices.
The onboard NCSI header is
used for external connections.
This header is used for IPMI
LAN LED features.
