This header is used to connect a Trusted
Platform Module (TPM), available sepa-
rately from a third-party vendor. A TPM is
a security device that allows encryption
and authentication of hard drives, disal-
lowing access if the TPM associated with
it is not installed in the system. See the

Unit Identier Switch/UID LED
Indicator
A Unit Identier (UID) switch and an LED
Indicator are located on the motherboard.
The UID switch is located next to the
VGA port on the backplane. The UID
LED (LE4) is located next to the UID
switch. When you press the UID switch,
the UID LED will be turned on. Press
the UID switch again to turn off the LED
indicator. The UID Indicator provides easy
identication of a system unit that may be
in need of service.
Note: UID can also be triggered via IPMI
on the motherboard. For more information
on IPMI, please refer to the IPMI User's
Guide posted on our website: http://www.
