Split Redundant Return

In the split redundant return configuration, each pair of RF returns is applied to a separate 2X redundant return configuration board. In a typical installation, the RF module in Ports 1 and 3 are connected to the 2X redundant return board in configuration location 2. The RF modules in Ports 4 and 6 are connected to the 2X redundant return board in configuration location 3. Both outputs of each 2X redundant board go to the same RF input channel on two different SG4-DRT- 2X transmitters located in lid optics slots 3 and 4, and 5 and 6.

Figure 9 illustrates the split redundant return configuration:
