TPM Header
The JTPM1 header is used to connect a Trusted Platform Module (TPM), which is available
from Supermicro or a third-party vendor. A TPM is a security device that supports encryption
and authentication in hard drives. It enables the motherboard to deny access if the TPM
associated with the hard drive is not installed in the system.
More information on TPM is available at:
