Introduction
1.2.2

Front Panel Indicators

There are six LED indicator lights on the front panel which indicate the status of the
SSPA and provide summary fault information. Refer to Table 1-2 for description of the
LED lamps:

1.2.3

Built-in Redundancy Controller

Each SSPA has the ability to function as a 1+1 or 1+2 redundancy controller in the
backup mode. The optional redundancy configuration is implemented by attaching a
ganged Waveguide/coax transfer switch(es) to input and output connectors of the
amplifiers with a combination coaxial cable and Waveguide kit. When the backup SSPA
is commanded into the controller mode, it monitors the online SSPA(s) for faults. A
faulted online unit may be disconnected and replaced without affecting the online power
amplifier.
