4.2 Headers and Connectors

Fan Headers
There are 12 8-pin fan headers
by Thermal Management using the BMC 2.0 interface.
TPM/Port 80 Header
The JTPM1 header is used to connect a TPM Module for Trust Platform Module/Port 80
support. The TPM module, which is optional and available from Supermicro, is a security
device that supports encryption and authentication in storage drives. It allows the motherboard
to deny access if the TPM associated with the storage drive is not installed in the system.
See the layout below for the location of the TPM header. Please go to the following link for
more information on the TPM: https://www.supermicro.com/manuals/other/TPM.pdf.
Chassis Intrusion
A Chassis Intrusion header is located at JL1 on the front side of the motherboard. Attach the
appropriate cable from the chassis to this header to inform you of possible chassis intrusion
when the chassis is opened.
BMC External I C Header
2
A System Management Bus 6-pin header for BMC is located at JF3_JIPMB1. Connect a cable
to this header to use the IPMB I
(FAN1–FAN12). Fan speed control for these fans is supported
