Unit Identifi er Switch
A Unit Identifi er (UID) switch and two LED
indicators are provided on the serverboard.
The rear UID LED (LE4) is located next
to the rear UID switch. The front panel
UID LED is on pins 7/8 of JF1. Connect
a cable to pins 7/8 on JF1 for front panel
UID indication. Pressing the UID switch will
turn on both the rear and front UID LEDs.
Pressing the UID switch again will turn
off both LEDs. These UIDs provide easy
identifi cation of a system unit that may be
