STATUS INDICATOR LEDS
Two large LEDs at the front card-edge indicate operational health of the module as follows:
MODULE OK:
This green LED indicates good module health. It will be on while a valid signal is
present at the video input, the output laser is operating properly, and the card power
is good.
LOCAL FAULT:
This red LED indicates poor module health. Three conditions could cause this fault
indication to be active: No valid signal is present at the optical input, operation of the
output laser is erroneous, or if a card power fault exists (i.e. a blown fuse). The
LOCAL FAULT indication can also be reported to the frame by setting the FRAME
STATUS jumper.
There are eight small LEDs on the back of the card-edge that indicate signal presence. Some of these
LEDs are Bi-colour, and able to illuminate as red, or green. The functions of these LEDs are as follows:
