These include the following:
Prime Not Learned: The Backup has not learned about the Prime(s).
Prime Polling Error: Either the Prime did not respond to the Backup’s
periodic polling, or something in the Prime’s
configuration has changed since the last time the
backup was told to ‘Learn.’
Note: Changing the Prime after the Backup has ‘Learned It’ will cause a Switch Fault until
the Backup is told to ‘Relearn’ the Prime(s).
Prime Relay Fault: The Backup has detected that the Switching Relay did
not switch when told to do so.
Note: Any Switch Fault will cause the Signal Fault LED on the Backup to illuminate. It
will also cause the Error LED on the 1:8 Switch to illuminate.
