The Redundant Loop Connector J4 is located near the waveguide output and is only
utilized in configurations where the SSPA controls waveguide switching. In alternate
configurations, such as "chain switching", another system block or external M&C
controls the waveguide switching. In this case, the connector remains unused and the
protective cap should be left attached. The pin-out specification is shown in Table 2-4.
