● 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 Collaboration Server are 

not backed up in the Slave Collaboration Server.

● 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.

● Collaboration Server 1500/2000/4000 only: 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.

To enable Hot Backup:

1 On the Collaboration Server menu, click Setup > Hot Backup.
