Anyone ever run into an issue with a 20i not being detected? Just installed one in an older 7400 to replace a 20e that had failed. The new card powers up, but is not detected by the system. Cabinet information shows no card in that slot. I have tried multiple slots with same results. I went through the pre-install process and have even cleared the memory and started fresh with a clean software install. No luck.

I tried the SVMi card in a spare system at the office and it works fine.

Some additional info on this: the old system was running software version 4.53c, so it obviously had not been updated in a very long time. I did update to the latest software version before installing the new SVMi-20i.

Did you update the LP40 card as well? That's the card that actually makes everything talk to each other on the 7400.

I forgot to update this earlier and wanted to follow up while I'm thinking about it.


This was exactly the issue. Thankfully, I found some documentation before I left the customer site that day that mentioned the need to upgrade the LP40 when upgrading to 4.60, I think, which was the first software version to support the 20i. Updated the LP40 and all is well.
