Unit Identifi er Indicators
There are two Unit Identification (UID)
indicators on the serverboard. The front

Control Panel. The backpanel (BP) UID
Indicator (UID1) is located between the
external SAS connector and the VGA port.
When you push the UID button on the
Front Control Panel, both the BP UID and
the FP UID indicators will be activated.
Push the UID button again to turn off both
Indicators. These UID indicators provide
easy identifi cation of a system from other
systems in the same rack.
