Figure 10.4 - Redundancy Switching Triggers
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
10.1.4 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.
