All C Class Interconnect bays got disabled

We had a c class enclosure running for last 3 years with no issues - one of many.
Today's morning all of the sudden all interconnect bays - four cisco 3020 switches and two fiber passthroughs got disabled.
All switches and fiber p/s were flashing blue light, all servers stayed up, but obviously lost all network and external storage.
OA still worked, but show no errors at all. In the active oa log I found that right before this happened active OA switched to the standby one.
After reseating all interconnect devices (pulled out and pushed back in) one by one all came back online.
We are behind with OA firmware, but the enclosure was running fine for 3 years.
I will be happy for any suggestions, right now everything is back to normal but I am afraid this might come back.
Could this be caused by bad OA? Midplane?

Yeah, nothing to do with firmware....
Actually, enclosure was running on one firmware for 3 years... with 14 servers inside, no new stuff addedd for over a year.
I know, that firmware is a nice thing to say if nothing else comes to mind.
It looks like we had bad active OA.
Firmware did not fix it.
