After back and forth email exchanges with Eastshore and Bitmain I think we have settled the issue of sending back the entire miner.  Bitmain says you can send just the board and not the whole miner.  I provided that info to Eastshore and they offered to cover the cost of the repair if I mail the board back to Bitmain.  Bitmain says the board repair cost is $35 plus shipping.  So clearly the shipping is going to cost far more than the repair.  Eastshore has offered to cover the cost of the repair.  I guess I will have to eat the cost of the shipping both ways.

So that is the latest scoop on the repair issue.  I will try to get this board in the mail tomorrow.  As always I will keep you guys posted.  I had another L3 decide to crash on me yesterday as it became quite warm here.  I didn't get to see what was happening before it went offline and started throwing a fault light.  I had to reboot, and reset the controller and then it came back online.  Cranked up the box fans to move some more air over it and just monitoring now.  So the Bitmain drama continues I guess!
