Guidelines
• Both Master and Slave MCUs must have the same software version installed.
• The Users list and Passwords must be the same on both the Master and Slave MCUs .
• There must be connectivity between the Master and Slave MCUs, either on the same
network or on different networks connected through routers.
• In the event of failure of the Master MCU the Slave MCU assumes the role of the Master
MCU . The Master/Slave relationship is reversed: the Slave , now active, remains the
Master and the previous Master MCU , when restarted, assumes the role of Slave MCU .
• No changes to the Slave MCU are permitted while it is functioning as the Hot Backup .
Therefore no ongoing conferences or reservations can be added manually to the Slave
MCU.
• If Hot Backup is disabled, all ongoing conferences and Reservations backed up on the
Slave MCU are automatically deleted.
• In Hot Backup configuration, the SIP and H.323 Authentication configuration of the User
Name and Password in the IP Network Service Properties - Security tab of the Master RMX
are not backed up in the Slave RMX.
• Master and Slave initial roles can be reversed only after all ongoing conferences and
Reservations are deleted.
• Changes to the Master MCU that require a System Reset can only be made after Hot
Backup is disabled.
• Video/Voice Port Configurations on the Master MCU are not synchronized with the Slave
MCU. You must manually set the Video/Voice Port Configurations on both the Master
and Slave MCUs to the same level.
