Hi, I had a power outage a week ago and now three of my antminer s9s are not connecting to the pool. They fire on and get an ip address from my switch just fine. I've tried changing out ethernet cords and doing a hard reset. Any other suggestions? Maybe firmware update?
Thanks in advance.

A better place to post this is the
Mining Support area where there may already be an answer to your problem. Can they connect to a different pool? You should also include a screen shot of the miner status page to show us condition of the hash boards... While possible that a re-flash of the firmware might be needed because BM uses the cheapest controllers they can get and is known for having issues with corrupt flash memory, generally updates should be done only if there is a valid reason to do it (eg getting LPM).
