configuration database
(CDB) in redundant backup
device when all connections
between redundant pair
have been removed
A redundant backup device
will start up as a passive device
and it will not be possible to
restore CDB to factory default
Use Modbus Host Port and send Modbus requests
using the common Modbus address. At first the
Backup device will not reply. After a while the backup
device will notice that the missing Active device is
not responding (since it is not connected). When the
Backup device has switched to Active deviceit will be
possible to make a forced unpair in the Web user
interface. Then it is possible to restore CDB to default
settings.
