Description
In a One-look network, if the Master unit fails or otherwise goes offline, a Slave unit that is designated as the
Backup Master unit assumes operation as the Master unit.
If the Backup Master unit also goes offline or none is specified, Slave units can switch to Isolated mode.
Backup Master Mode
When the Master unit goes offline, the Slave units will detect the change in status. The designated Slave unit
will switch to Backup Master mode, and the other Slave units will use the Backup Master unit as the Master
unit.
