STATUS INDICATOR LEDS
LOCAL FAULT:
Each of the two 7707VB-8-ASI-OC3 boards has a red and a green local fault LED.
The red LED on either board will be ON if a local board fault exits, such as a blown
fuse. On the board that also has the pushbutton and display, a red LED also
indicates that a laser fault exists, or that the laser is set to Discontinuous mode with
no valid inputs present.
The LOCAL FAULT indications can also be reported to the frame through the
FRAME STATUS jumpers.
MODULE OK:
This Green LED indicates good module health. It will be ON when a valid input
signal is present, and the laser and board powers are good.
