Reconfiguring Forward Signal Routing
1x4 Redundant Forward Configuration Modules with Forward RF
Injection
A primary receiver (RCVR 1) and a redundant receiver (RCVR 2) feed all RF output
ports. The FLI Module routes an RF signal from an external source to the Forward
Configuration Module which is then coupled with the input from RCVR 1/2.
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. Install
the FLI module in the RCVR 4 position. When using this module remove the 0.5dB
forward interstage attenuator pads and replace with 0dB attenuator pads.
