I have 250 units. About 8 of these randomly turn off for no reason at all. T
What do these 8 miners have in common? are they on the same breaker? switch? rack? when more than 1 miner acts the same it's usually an outside cause.
here are no errors, temps are fine, I tried different psu, different control board, fans are at 97%. If you know what the reason is please let me know. Thank you.
Miners turn-off or reboot for many reasons, heat is the most common, if the miner's temps are fine it could be PSU, if the PSU is dirty or isn't getting enough air flow it i will stop, also if the voltage goes out of the 200-240v range it can trigger protection mode.
The good news is here

All three hash boards are in good shape, finding the complete asic count in the first trial is a good sign.
Since you have 250 of these, I don't think I should be telling you this, but you sure your router/switch can handle all the traffic? that could also be the reason why.
My router is set to be able to handle 750+ ip address. So thats not the issue. But it could be the voltage drop or voltage increase from the panel. So what happens is that these miners randomly turn off and yes they are all located in one area. Even though some miners in that same area do not have these issues. It might be the panels voltage changing for some reason. I will look into that. As for the other possibilities. All these miners are brand new and have brand new PSU. I even tried replacing 2 psu but still same problem. I tried new control board but still same problem. The really weird part is when the heat outside get to 50 degrees then this happens. Even though the miners are super cold. It might be something with the panel. The Electricians could have made a mistake somewhere.
