Please connect a NMI device
to this header.
This header is used for PWM
configurations.
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.
Please connect the thermal
sensor cable to either pin 1-2
or pin 2-3 and the other end to
