This connector supports
Trusted Platform Module
(TPM) system for SPI
interface, 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.
