TPM Header
The JTPM1 header is used to connect a Trusted Platform Module (TPM)/Port 80, which is
available from a third-party vendor. 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. See the table below for
Chassis Intrusion
A Chassis Intrusion header is located at JL1 on the motherboard. Attach the appropriate cable
from the chassis to the header to inform you when the chassis is opened.
