This connector supports
Trusted Platform Module
(TPM) system, which can
securely store keys, digital
certificates, passwords, and
data. A TPM system also helps
enhance network security,
protects digital identities, and
ensures platform integrity.
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.
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 temperature.
