Backup FCI CI820 not operational
We at our site have CI820 FCIs installed in redundant configuration on all stations.
At one station the backup FCI run LED is not on. Power and T1 & T2 leds are okay. Also Fault LED is off. We have tried replacing the module with new and also tried swapping it with another station's backup module. Neither of the two actions has resolved the problem and the healthy station from which we removed back up module now also has the same issue...
Appreciate if someone could help us out in resolving the matter.
