Unit Identifier Switch
A Unit Identifier (UID) Switch (SW1) and an LED Indicator are located on the moth-
erboard. The rear UID is located next to the QSFP port, and the Rear UID LED is
located at UID_LED1. When the user presses a UID switch, the UID LED Indicator
will be turned on. Press the UID switch again to turn off the UID LED. The UID In-
dication provides easy identification of a system unit that may be in need of service.
