Configuring the Protection Router
To provide full module redundancy, the input audio/video signals feeding a failed module need to be transferred to the backup module during a failover operation. This way, the backup module receives the same signals from the upstream devices that were reaching the main module prior to the failure condition. Similarly, the output signals from the backup module need to feed the downstream devices that were once fed by the main module prior to the failure condition. This is accomplished by having a router managing these signals via inputs, outputs, and cross-points. When you configure the Routers section (found under Redundancy) on the SEL-MCP3 controller to represent your existing physical/logical routing system configuration, the interaction between the controller and the external router happens smoothly during failover/failback (router protection) operations.
When using Legacy router protocol, the controller can perform cross-point switches to a 16-level router (with each level having up to 32 inputs and 32 outputs). LRC protocol does not have this limitation. You can configure the protection router to route the signal in case of module failure.
The connections manager must be configured to use the connections you have just created before any protection router features are enabled.
