OK So got my PSU back after sending it to Serbia for repair (the only place in Europe) - cost a lot in postage
Installed and got it working ok and worked fine for about a week then the same thing. Orange LED and red flashing LED
Got back in touch with the service guys who says it is overheating protection - has been unusually hot in UK recently.
But they cannot tell me how to reset the PSU as against company policy.
Anyone know about this and how to reset the PSU?
Or is it possible to use the ones for sale on the antminer site by adapting the cable to take the older style connectors (not PCI)
thanks for any suggestions
