Post a picture of the power supply and the back of the miner (where the power supply PCIe connects to it) - are the lights on the back of the miner on?
Is the power supply the right voltage? Are the pci-e cables the right wiring? (if you hold the cables the same way, are all the wires the same color)?
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.
do you have any working avalon's?
I've tested three miners, all with separate PSUs but none are visible through the controller's cgminer status page so if we have a problem with the miner/PSU it's common to all three.
