Hi,
I have a toughpower 1200W gold. It has one rail. I tried several different ways of plugging in the cables, I tried 4 different cables, and since each cable has two connecters I tried it with just two cables in four slots. Nothing happens
I tried powering just two cards, still no joy.
With the case off, the only light on is a blue light that flashes it is very fast it might be several lights in sequence.
With the Ethernet unplugged there are no Ethernet lights, when it is plugged in either on my network or on my laptop not on the network the red and green light flash.
I tired it on a coolmaster 750 from the S3 just to see if it would work same thing, it never seems to try to boot.
On the cool master it draws 150 watts at the wall. I reported it to Bitmain and they sent be a diagram of how to hook up the cables one on each card. I had that part correct.
Thanks
Barbara

can you SSH?
sounds like a controller issue - heres what id try:
1) open the unit, check all cables are seated. eject and re-insert the SD card. Test.
2) unplug 3 hashing boards (from both power and the controller). Test
2b) if not, try with it powered/plugged to another singular card. Test
3) buy a new micro-sd card and format/image it with the newest firmware. Test.
get a class-10 card. usually miners are shipped with crappy class-4 or class-6 cards that can have its data corrupted or even cause the card to be un-formatable. Ive seen this in the S2 which uses the same controller. This is most common
Not sure how you still expect them to provide a replacement when you've already refunded your credit card AND paypal payments.
