Trying to figure this out and could use help. I'm a new miner. Did it previously with my computer and gpu just for fun and to learn. Finally got a couple S9's.

Set them both up today. They are both on 240v outlets. They are on shelving in my garage, which is currently 32*F right now. Temps of the unit are about 72, 68, and 71 when in operation.

It ran great for about 6 hours. Then nothing, slush notified me my worker was offline. Tried accessing it via browser and ip, nothing. The 3 hash board red lights were out. Unplugged and replugged, it all came back. Worked for about 30 minutes. Then lost network again, couldn't access. Left it "just in case it came back". It didn't. Unplugged and replugged, worked again, went about 5 minutes, did again, this last time about 20 minutes. Tried resetting to factory and setup again, no difference. What am I doing wrong? Frustrating!

No thermal shutdown, just after a while, it loses network connection and the red board lights go out. Power connections and data connections are all good.
The boards do not have any XXXXXXX.

Please Help!

Try it on 110, see how long it lasts. Did you switch power supplies with the other s9?

I thought these performed poorly on 110/120, but I'll give it a try with the problem machine. I did switch PSU's with each other, no difference.

It may perform "poorly" but see if the problem follows.
