help with AF!00 CI820V1 Card Replacemen1
We have had a CI820V1(AF100 Extended IO Modem) Card Fail (hardware Fault). The card was in a Redundant configuration. The fault meant that the backup became the primary and the Dual redundancy (DU LED) was lost as expected.
Once the New card was fitted and powered up the run (R) LED and Dual (DU) remain off and the second card remains as primary. It is as if a Signal is required to get the card to run and then I imagine a Changeover command is needed to make primary again. I am unable to find this commands or any reference to them in the manuals.
The manual just states in a redundant configuration a faulty card can be replaced online with no impact on the system.
Does anyone know how to get the new card up and running fully?
A couple of things to consider here:
1. Was the station address switches set to correct positions before power up?
2. Software version of the CI820, the same on both CI:s?
And as always, one needs some more information in order to help you:
1. What type of controller?
2. Status on DB element?
3. System messages?
Any other observations?
