TPM/Port 80 Header
The JTPM1 header is used to connect a Trusted Platform Module (TPM)/Port 80, which is
available from Supermicro (optional). A TPM/Port 80 header is a security device that supports
encryption and authentication in hard drives. It allows the motherboard to deny access if the
TPM associated with the hard drive is not installed in the system. Refer to 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/AOM-TPM-9670V_9670H.pdf.
Note: If PCH SLOT1 is to be installed with a 3/4-length PCIe card and/or CPU SLOT2 with
a double-width 3/4-length PCIe card, the TPM module for JTPM1 should be a horizontal one
to prevent mechanical conflict.
