Redundant System Operation
4.1 OVERVIEW
The Comtech EF Data UT-4500 Series Up Converters are configured for redundant
system operation using distributed protection switching in an active "Daisy Chain"
configuration. Comtech EF Data's Proprietary "Daisy Chain" configuration distributes
the converter protection switching functions in the converters.
This provides a system capability to backup from 1 to 12 online converters. A High
Speed Bus (HSB) provides the communications interface between the backup and online
converters to detect faults and reconfigure the subsystem to replace the failed converter.
When a faulted converter is removed from active operation, it is detached from the active
converter chain by separating the converter from its switch module, leaving the active
online converter chain intact through the switch module. The chain can be extended
without affecting the online converter operation.
The active "chained" converters in a redundancy subsystem can also be indirectly
controlled through the backup converter using the remote serial communication link -
this capability is discussed in Chapter 5, Remote Control.
