If you are in the US and determine you need to RMA - my advice is to forget it. Contact bitmainwarranty.com and send them your miner to fix. You'll have to pay for it, but on the plus side you will actually get it back. I sent a dead S7 board to Hong Kong per their instructions. They claim it was never received. It's a black hole over there. To me it's actually worth it to spend the extra $ to buy the miners from bitmainwarranty.com.
Even if the Hong Kong facility repaired and returned the hardware, the lost time mining makes it near useless. IMO
