1x4 Redundant Forward Configuration Modules
A primary receiver (RCVR 1) and a redundant receiver (RCVR 2) feed all RF output
ports.
The Status Monitor/Local Control Module automatically switches from primary
receiver to redundant receiver when it senses a loss of optical input to the primary
receiver. Once optical input is restored, the system automatically switches back to
the primary receiver.
Install the primary receiver in RCVR 1 and the redundant receiver in RCVR 2.
