I think one of the hashing boards in one of my November Jupiters just failed.

Basically, whenever I connect power to this board, it seems to short out the power supply so the power supply won't turn on. I've tried two different power supplies, and the same thing happens with them both when this board is plugged in.

The unit runs fine with the other three hashing boards plugged into the power supply.

I'm going to remove the bad board and inspect it tonight, but I think it's done.

This Jupiter started acting up a week ago and would randomly stop hashing, and I suspect this was the cause.
