In non-redundant converter configuration the converter has an Input/Output Module
(IOM-XX) for the RF input and the IF Output. A converter with a Transmit or Receive
Switch Module may be operated in a non-redundant configuration if an IOM is
unavailable. Figure 7 is an illustration of the converter cable connections with an IOM
installed. Figure 8 is an illustration of the converter cable connections with a TSM
installed.

ABLE ONNECTIONS
In subsystems where a redundant converter configuration is used, the backup Converter
has an Input/Output Module (IOM-XX) and the online converters have Receive Switch
Modules (TSM-XX) which switch to the backup Converter when a fault is detected.
Redundant system operation is discussed in Appendix A, Redundant System Operation.
