3.1 Operation of the Cougar Digital Video Routing Swit.
General
The operation of the Cougar Digital Video Routing Switcher consists of
periodically monitoring the 32X32 Digital Video Matrix Card LEDs. The
matrix card LEDs and their proper indications are discussed in the follow-
ing manual sections.
3.2 Regulator Fault LED (Red)
The Regulator Fault LED (CR5) is utilized to visually indicate a regulator
problem on the matrix card. A problem with the power supply or regulator
circuits will cause this LED to light. However, in the event of a total power
outage this LED will be rendered inoperable.
3.3 CPU Fault LED (Red)
The CPU Fault LED (CR6) is utilized to visually indicate a microprocessor
problem on the matrix card. A problem with the CPU or controller circuits
will cause this LED to light.
3.4 Power OK LED (Green)
The Power OK LED (CR7) on the front edge of the matrix card is utilized
to visually indicate that the proper power supply voltage is being supplied
to the card. A decrease in the brightness of this LED indicates an approxi-
mate 12% drop in voltage and should be checked. A 25% drop in voltage
will cause the LED to extinguish.
3.5 32X32 Digital Video Matrix Card Adjustments
There are no user adjustments on the 32X32 Digital Video Matrix Card.
