Im running my T15 at 200v since Tuesday without issue. How long have you waited between trying to get it running again? The APW5s I have, when they trip into protection mode, can take 15 minutes of being unplugged before theyll respond to power input again. I wonder, what are the stats on the APW8?
I was thinking that too. Did try to re-power the units a couple times over the course of a few hours, but no luck. One unit was in my basement, about 60 degrees ambient and only ran for about 45 minutes. The psu on that unit was quite hot to the touch just after it lost power. The other unit was in my garage, about 35 degrees ambient. That unit ran for 11 hours before it lost power, again, the PSU was quite hot to the touch. I put a meter on both the outlets and they tested 240v. I will take both S15's back into the office Monday and put them on the rack at 208v and see if they power back up, or if something inside the PSU is actually blown. I would like to open them up and do some power troubleshooting but I don't want to void the warranty in case they need to go back. Bitmain doesn't seem to be offering any spare parts for these yet. I don't know if my experience is typical but I wanted to throw out a word of caution if anyone else is operating these at the high end of their voltage rating.
