Trouble shooting wise.
Make sure all the power cables are correctly attached.
Do a hard reset on the device:
The cables are correctly attached (powering down wouldn't have changed them in any case)
I did a hard reset then ran through all the various firmwares before I posted.
Lastly, If you can isolate the bad board, then you can just return that bad board for an RMA and the miner can continue mining, you don't have to lose the entire miner and 480Gh/s just for one bad board.
I have isolated the bad board. Being able to RMA a single board changes things somewhat. I will probably do that after the next difficulty increase.
