10.2 Internal Redundancy
Internal redundancy refers to the process by which a QAM, ASI, IP Output modules, can
receive configuration from two different MMI boards, but not at the same time. This section
describes internal redundancy for these cards in detail.
The chassis will have two switches/MMI modules. One switch will be configured as the main
switch while the other switch will be configured to be the redundant switch. Please note that
internal redundancy configuration is currently only supported for IP input modules, ie Switch+IP
or IP Input.
10.2.1 Dual backplane configuration
The figure below shows the signal flow within the unit when having two backplanes, one MMI
card connected to backplane 1 and second MMI card to backplane 2 respectively.

10.2.2 Hardware Requirements
The following hardware is required to implement internal redundancy, either:
Two Switch management cards and Two IP input modules
or
Two Switch + IP modules
In addition, one or more output modules are required to implement internal redundancy.
10.2.3 Configuring Modules for Internal Redundancy
Configuring internal redundancy is done by selecting Redundancy  Internal in the Navigation
Pane. This will load the configuration page displayed below.
