10.5 MMI Redundancy
MMI Redundancy is designed to protect the system from MMI card hardware failures. In case of
an MMI card failure the system shall switch to the backup MMI card in slot 17.
MMI Redundancy will also automatically synchronise the configuration database between the
two MMI modules.
The following cards support MMI Redundancy:
• Seamless IP Input
• IP output
• Dual IP Clone output
• Encoder (SD/HD)
• Transcoder (SD/HD)
• ADM
• ASI OUT
• Universal Transcoder- Multiscreen
• Universal Transcoder- Broadcast
The two MMI cards must be able to communicate in order to synchronize the database.
Currently this is performed via the external management port on the two MMI cards.

10.5.1 MMI Redundancy Configuration
In order to configure MMI Redundancy, the Switch module must first be changed to this mode.
This is configured in the Maintenance Center and you can find details on this procedure in the
Upgrade Guide.
Once configured, the GUI page for MMI Redundancy will replace the Internal Redundancy
page. This page will be slightly different depending on which MMI the user is accessing. We will
refer as 'Main MMI' for MMI on Slot 0, and 'Backup MMI' for MMI on Slot 17.
