CI820 help required
How are you ?
Need a bit of help !!!
I have an AF100 Bus Station 25 which is configured as redundant CI820s. The secondary card is unhealhty i.e "Run" & "DU" LEDs are OFF and all other LEDs except fault LED are ON. I have another station 23 which has both Pri/Sec CI820 cards healthy. What i have done is taken the secondary card of Station 23 and installed on Station 25. However, the installed card didnt work on Station 25and the status is as it is.
Now i have taken the CI820 card out of Station 25 and re-installed on Station 23 which is its origianl station. But Station 23 also didnt pick the card. now i have two stations with Secondary card CI820 unhealthy. I have tried new cards on Station-23 but failed to pick the card. What could be the possible reasons for this ?
The software version for every installed card was made sure and it is 2.2/3. The station address switches were correctly directed on each time the card was installed. Is there any software issue which can be propagated from one station to another ?
