Redundant Configuration - Comtech EF Data XTD-750C-B1 Operation And Installation Manual

Redundant configuration

Refer to Figure 16. The XTD-250KA amplifier has built-in Waveguide
switch control and indicator functions. Two HPAs can be configured in a
1:1 redundant system without an external system controller. In
Redundant configuration one amplifier constantly monitors the operation
of the other amplifier so that if the online amplifier becomes faulted, the
backup amplifier will take its place. This automatic switching requires that
the backup amplifier must be operational (not faulted) and in automatic
mode. Please refer to the system manual for more details on redundant
switching.
