same thing here but I am using a Corsair CS750, got 2 units both are going crazy for few min and then they die., there is a red light on one of the units and one flashing green light next to it.
I just got my first Antminer S1 yesterday. I went to set it up and it won't stay on more then a few sec. I'll turn on the power and It will flash a few green light on the side. The ethernet ports will light up and then when i go to log in about 15 sec after it Flashes crazy fast green lights on the side and dies. WTF?
What size power supply are you using ? If your supply is under powered it will shut off after a few min
600 watt Corsair. But i guess it could be bad. I'll go buy a new one in the morning

I did't even check dose this company do returns/replacements?
how long do you hold down the reset button?
sounds like a PSU issue. I have a Corsair C600M with 552W of 12V power and it ran an overclocked antminer without problems. However, not all power supplies can push full capacity for 24/7 and some may not be able to hold more than 80% of the peak rating for a long time.
Try disconnecting power from the secondary blade and try again. If the device runs 90GH without problems but is having issues with running both blades then its a PSU issue
