Guidelines for Implementing Hot Backup
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.
