hello everybody,
I've paid for 2 s4 batch 1 that received last friday. Both of them were working ok with default parameters (not overclocked yet) until yesterday night that one of them was powered down and now I'm not able to power on it again. I've tried unplug the wire, changing the wires between them, but the result continue to be that this machine doesn't work.
Any suggestion please?
Thanks in advance.

I had a power unit go down last weekend.

While you're waiting, you could try plugging in a different PSU to the controller board and to one mining board. If that seems fine, or you have a large enough PSU you could test the entire unit with it. Does sound like a PSU problem.
