INSTALLING REDUNDANT VM 3000 CONTROL PROCESSOR
In a redundant installation, each VM 3000 monitors the other. If a fault is detected in the active unit, control will be switched
to the other device automatically. Wiring for redundant VM 3000s is shown in Figures 2−4 and 2−5. For software configura-
tion, see Step 4 on page 5−23.
Note 1: Only late−model VM 3000 Control Processors can be operated in redundant mode. Please contact Grass
Valley for additional information.
Note 2: Automatic changeover is not available for the party line port or the VGA port.
Note 3: For information about manual changeover, and a maintaining a third unit as a replacement for a failed re-
dundant unit, see Appendix K.
