When the Avalon is turned on, immediately the red light comes on & it won't hash. The fans aren't spinning either.  Huh
Replacing the PSU... nothing
Flashing to ckolivas' newest firmware... nothing


Ive been having similar issues, when using http://ocz.com/consumer/psu/zx-series-850w-1250w-power-supply ZX Series 850W-1250W - Power Supply
I get red and yellow leds and the fans dont spin.

When placing the original power supply back in fans spin and I get yellow and green leds.

Ive checked all connections to make sure nothings unplugged, reflashed the wr703n, unsuccessfully tried replacing the power supply(red and yellow led), copied every setting from a functioning avalons luci/cgminer settings.

I've posted the system, kernal and cgminer error logs here.

As well I understood Avalon works without problems with original PSU  ?
If not remove all modules and try run with  one. Than check next one.

With the orginal PSU the fans spin, wr703n functions fine but we still have a yellow/green leds.

When you talk about removing a module to you mean removing the power chord attached to the module, removing the pci data ribbon or both?
Yes both, data and power connector from all modules, and start connecting one by one.

Would i remove the power from the pci ribbons at the fpga or at the chips? Do I need to change the miner count for running one module? I cycled threw and unpluged the power from all but one and then pluged in one at a time and rebooting the avalon to no avail.

Thanks in advance.
