This is my third antminers7, and it all of a sudden stopped hashing. At this point i can't connect to the configuration page, and the four led on the controller board are lit except the D1 light which is blinking. I have tried the reset button and multiple hard resets but still nothing.
Any ideas?
The basic things to check are
- Power down the unit and unplug all PCIE Cables and leave them unplugged for a minute or two, during this time check all connections on the miner to make sure nothing is loose
- Check PCIE Cables and make sure they are seated properly and not plugged in backwards (I've seen someone do this and somehow the miner still powered on). It worked fine after the cables were connected properly. DO NOT HOT SWAP PCIE CABLES
- Contact Bitmain for warranty support if still in support period
Hope this helps, good luck!
The hot swap is a big deal. OP did you try any updates? Or move around any cables?
Or did this just happen with nothing new added to situation?
I didn't do anything to it at all, it just happened out of the blue and i don't have anything to add. I am going to try power it down and removing the cables to see if that changes anything.
I have already tried changing the Ethernet cable and the switch so I am pretty confident that this is not a network issue
