Unit Identifier Button
There is a Unit Identifier (UID) button on the
rear I/O of the board. There is also another
UID button located on the control panel.
When you push either UID button, both
Rear UID and Front Panel UID Indicators will
illuminate. Push either button again to turn off
both indicators. These UID indicators provide
easy identification of a system unit that may
be in need of service.

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 definitions.
