What color are the lights on the AUC converter that's hooked up to your Pi?
Are the lights on the back of the miner, where you plug in the PCI-e boards, on?
okay looks like some thing is broken
wait wait wait check this thread

you can get to the rasp pi and program it so the eth cable looks good.
next usb micro cable to the auc conveter ---------
auc converter ---------------------------------------
four pin wire to unit --------------------------------
if any are bad you would get the symtoms you are getting.
so do you have multiple units and parts?
do you have a working unit?
if yes fully swap
the usb
the auc
the four pin wire
if dead unit works you know that one of those 3 parts are bad.
if good unit works you know that all of the part are good since each set works on good unit.
next swap psu from good unit to bad unit.
if bad unit works you know it is a psu issue.
if good unit works if means the psu is good.
at this point it would be an internal issue in the gear.
a hash board or the internal daughter board
the gear does not work if you have one bad hash board.
I did a rma check here
