The switching hysteresis is not configurable
MMI functionality remains on the same card after a switch
Switching can be done manually via the GUI
Switching behavior depends on the switching mode set individually for each pair
Alarms that are filtered through the alarm filter GUI will not trigger source switching
12.1.4 INPUT REDUNDANCY AND THE MMI
Input redundancy does not affect MMI functionality. If the main input module is configured as supporting the
Man Machine Interface (MMI), this configuration will remain even though all input sources are switched from
Main to Backup card.
12.1.5 SEAMLESS INPUT REDUNDANCY
The Seamless IP input module allows two input interfaces to be connected to different network sources, but for
the system, this is a single module. Configured multicasts are subscribed to on both interfaces. Depending on the
configuration, there are options for these multicasts must come from the same or different source.
12.1.5.1 Seamless IP Interface selection
For all Seamless IP input modules, it is possible to set the preferred port and/or redundancy switching mechanism.
This is available on the Admin page of the Seamless IP Input module:
