Dogie,

I see some people only connect two PCI-E's to the S5. Is there harm in doing this?

thanks,

Rtt

No harm but if you were overclocking it will need the 4 PCI-e possibly. All depends on frequency.

Yup, and depends on the AWG of your PSU cabling. 2 PCI-E is only possible on TWO cable rails, and only recommended on 16AWG.

Thanks again for the Help Dogie. It is the BBB (which is not held down by a screw but it is easier to remove the board and separate it away from the machine).

Okay, so you have the options of contacting Bitmain if its in warranty, Bitmain if its not and you want to pay, your seller to send it back or to get another one locally.

Any suggestions as to what could be wrong? They shipped as if they were packed well, no damage to the box. I had the former owner send me a screen shot of them hashing (could be faked i suppose) and they were going fine.

What was his network configuration, DHCP or static? All the white ribbon-esque cables look secure?

Thanks for the quick response Dogie.

Yes all the cables look secure. I believe all the miners are on DHCP right now. Again my 1st and 2nd miners are going fine. This one just the fan's boot up, can not get to the control panel to get into any settings it is not connecting to the network.

the 4 green LED's on the top board are all solid.

Thanks. Quickest way to debug this is to unscrew the 4 black screws holding the controller + adapter down, and swap that with one of the working S5s. Put the non working one on one of the working S5s and see if the problem moves or stays. Then we'll know if its hashing boards / power, or controller.

Thanks. Looks like it is the controller. Swapped it over and the unit that wasn't working is, and the unit that was working isn't and displaying the same lights/issues.

Is there anything that can be done to repair it or does it need to just be replaced?

If you've held the reset button and that hasn't worked, then you can try another quick swap. Swap the Beaglebone Blacks off the controller boards and see if the problem moves again. Then we'll know if its the controller board or the BBB which can be replaced locally. Although for both you'll have to get in touch for a repair or send it back to your seller.

Ok still a noob, I assume that is the black card? any hidden screws or just pull up?

The beagle bone black is the "black card" that controls the S5.

I don't believe it is screwed down if i remember right. I think it's just on the pins. You would see a screw in one of the holes if it is.
