I will get a picture up when I get back soon. The light on the miner is green. The light on the AUC3/USB dongle is also green. The PSU and cables came with the unit direct from Canaan. Will confirm about the wiring.
What country are you in? Are you running 220v? (The canaan power supplies only run on 220).
How is power getting to the PSU - through an outlet, a PDU, etc? What's the power outlet look like?
In the US. PSU is plugged into a regular socket at that has 220v going to it through a GFI. Will post a picture when I get back.
Edit: From a software perspective, what else could I troubleshoot? I can see my worker on the nicehash dashboard, which leaves me to believe pool/internet connectivity is okay. One question I was unable to find a clear answer on is whether cgminer may need ports forwarded on the router but I don't think it does as the communication with the pool is outbound only. I haven't changed any other configuration on the Raspberry Pi unit as I anticipated it would work out the box but if anyone has had similar issues that were resolved by change to the software configuration, I'd like to hear what you did.
Thanks for your thoughtful replies. Will get those pictures up asap.
