connected after sometime.
Both FTE cables of the secondary PGM are removed and re-connected after sometime.
Both the primary and the secondary PGM generate this notification upon detecting a
compatible partner visible across the redundancy private path.
Both the primary and the secondary PGM generate this notification after both FTE cables
are removed and re-connected and the initial synchronization is started.
Both the primary and the secondary PGM generate this notification after completing the
initial synchronization.
This notification is generated when the redundancy link cable is connected.
