I would remove all cards except the 1st 412 and the 016. I would also take the expansion unit off.

Then I would test to see if the 016 worked or not.

If not, I would use different 412's, one at a time in slot 1.

If the 016 works, then you can determine that one of the 412's is killing it, or if it works with all of them, then re-install the expansion unit.

Then test to see if any of those modules kills the 016.

Since there was a storm involved, isolating the trouble may be very difficult.
