TPM Header
The JTPM1 header is used to connect a Trusted Platform Module (TPM), which is available
from Supermicro. A TPM 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 storage drive is not installed in the system. For more information on the TPM:
