STATUS INDICATOR LEDS
LOCAL FAULT:
On the 7707VR-8A main board this Red LED indicates poor module status and will
be ON during the absence of a valid fiber link input signal or if a local input power
fault exists (i.e.: a blown fuse).
On the 7707VR-8B sub-board this Red LED will be ON if a local input power fault
exists (i.e.: a blown fuse).
The LOCAL FAULT indications can also be reported to the frame through the
FRAME STATUS jumper.
MODULE OK:
This Green LED indicates good module status. It will be ON when a valid input
signal is present, and the board power is good.
On the 7707VR-8, there are nine small LEDs on the front of the board that indicate the optical link status
and the presence of video signals.
