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 connector 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
motherboard layout in Chapter 1 for the location of the TPM header. Please go to the following
link for more information on the TPM: http://www.supermicro.com/manuals/other/TPM.pdf.

Fan Headers
There are eight 6-pin fan headers (FAN1-FAN8) and two 4-pin fan headers (FAN9/FAN10)
on the motherboard. These fan headers are used for the cooling fans for your system. Fan
speed control for these fans is supported by Thermal Management via the BMC 2.0 interface.
Refer to the motherboard layout in Chapter 1 for the locations of the fan headers.
