ID_UID Switch/Drive LED
The UID Switch/Drive LED connection is located on pins 13 and 14 of JF1. The UID switch
is used for a chassis that supports a front UID switch. The front UID switch functions in the
same way as the rear UID switch; both are for input only and cannot be used for output.
When this LED is blinking green, it indicates drive is active. Attach a cable to pins 13 and 14
to show ID_UID status and storage drive activity.
