The T-SGPIO1/ T-SGPIO2 (Serial
General Purpose Input/Output)
headers provide a bus between the
SATA controller and the backpane to
provide SATA enclosure management
functions. Connect the appropriate
cable from the backplane to the
T-SGPIO1 header to utilize SATA
management functions on your system.

Trusted Platform Module Header
The JLPC1 header is used to connect
a Trusted Platform Module (TPM),
available separately from a third-party
vendor. A TPM is a security device that
allows encryption and authentication of
hard drives, disallowing access if the
TPM associated with it is not installed
in the system. See the table on the
right for pin defi nitions.
