GUIDE TO INSTALLATION AND OPERATION
FIO-991p | 15
3 Operation
There are no operating controls on the FIO-991p.
Configuration is automatic, depending on the model and the installed SFP
module.
3.1 Status LED assignments
The FIO-991p includes two arrow-shaped status LEDs, integrated into the
case’s graphics and labeled appropriately, which monitor the status of the
inputs. The arrow shows the direction of signal flow, and the color shows the
status of the associated input. The functionality of the LEDs varies with the
model type, as shown in this chart:
FIO-991p model LED 1 LED 2
TT Electrical In A Electrical In B
T Electrical In A
RR Optical In A Optical In B
R Optical In A
RT Electrical In A Optical In A
RD Optical In A
MADI-RT Electrical In A Optical In A
3.2 Status LED behavior
LEDs assigned to monitor Electrical Inputs display this behavior:
o Green = SDI signal OK
o Yellow = No lock
o Red = No signal
LEDs assigned to monitor Optical Inputs display this behavior:
o Green = Optical signal OK
o Yellow = No lock
o Flashing Yellow = Input level too high or too low
o Red = No signal
In addition, LEDs in all models monitor the status of the installed SFP
module. The LEDs on any FIO-991p will flash red in the following cases:
o No SFP module
o SFP mismatch – wrong SFP type for the FIO-991p model
o Tx laser fault (SFP transmitter modules only – faulty channel LED will
flash)
