Problems with A2 Terminators - Wont start up

Firstly: In normal operation the LED's flash green util they cycled the startup script and when all is returned well the will be continuously green. When some of them flash green and some are off, that means that the card that is off is defective somehow. I don't know what the red flashing means Sad

Secondly: I assume you have switched out the defective PSU.
When I got my A2 mini I switched the crappy PSU for a silent more efficient one.
I noticed that when comparing the stock PSU with the PC PSU (I don't know if that is always so, but it was in my case) the polarity on the pci-e power cables (that go to the blades) were reversed.
Possibly that is in your case as well. If you still have the old PSU with cables attached to it, measure the polarity.

Thirdly: What software are you running? If you have old A2's you might try: https://bitcointalksearch.org/topic/ultra-under-overclock-image-for-a2-innosilicon-by-emdje-v50-672969  <---New A2's are not supported in my software

I have two units that behave differently  

-both started out with bad PSU's 1k watt PSUs came with the units even though the Innosilcon claims that the units need 1200Watt+ psu
they just happened to shit with defective 1k watt PSUs hmmmm.

To the problems

- the first unit powers up when none of the asics are connected to the PSU.  If I connect even a single of the six ASIC boards the
unit will not power up.  There are lights on the controller board and on the rasbery-pi but the fans don't spin asics don't light up.

-second unit powers up but the asics do not initialize , the LEDs on the asics all flash red , similarly to when normal units first power up .


I have tried single Asics connected , multiple PSU's from 1200Watts to 1k watts to no avail.

Anyone ever experience anything like this ?

I just want to ship the damn units back to be honest but they claim the issues can be resolved would pay LTC/BTC bounty if someone get these up and running otherwise ill just have to pay the shipping price to get these replaced.
