I purchased a new Antminer D3 on ebay. I purchased a new Bitmain APW3++ PSU. All power cables connected per Bitmain's manual.

When it starts the fan is at low speed. After about 30 seconds it starts running at high speed. The web interface only works when the fan is running at high speed. It cycles from low to high speed about every 30-45 seconds. The status page shows nothing in any of the fields. The "normal" light and all the other lights on top of the Antminer are blank.

The Overview page has the following under hardware version: Socket connect failed: Connection refused

I have let it run cycling like this for over a half hour. I'm not sure how to proceed.

Thanks in advance for any advice.

One of mine is bad also, I think. A buddy had a similar issue and self resolved through a few power cycles. Also the reset button.
Of course, makesure firmware is updated. I saw that error and it went away with power cycle and letting it run for 10min.

Lastly, they do this. Rev the fan. Make sure you wait five minutes each attempt.
Good luck! Keep us posted!
