2.4.5 CABLE CONNECTIONS FOR NON-REDUNDANT SYSTEM OPERATION

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 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.

2.4.6 CABLE CONNECTIONS FOR REDUNDANT SYSTEM OPERATION

In subsystems where a redundant converter configuration is used, the backup converter

has an Input/Output Module (IOM-XX) and the online converters have Transmit Switch

Modules (TSM-XX) which switch to the backup converter when a fault is detected.

Redundant system operation is discussed in Chapter 4, Redundant System Operation.
