J11 is on both boards. It is the 3pin black and white wire that plugs in directly behind the intake fans. This J11 wire runs into a small board next to the power supplies; a board located in the side compartment with the power supplies. One of my J11 plugs had the black rubber crap over it to hold the plug in so yours might be covered but its there. Here is the PDF they sent me. I have not tried pressing the reset button and I dont hear any clicking. I have been keeping this board powered off since its not working. Not need to have power running to it. I do have two other units running also below this one. I noticed there is a reset button on the outside front center top of the case and each internal board also has a button but I dont know what this one does. As far as one board having a jumper and one not I think this is just to signify and master and slave board

There are no J11 cables in either of my units. It is simply a dead plug as far as I can tell. The beaglebone has it own wire that can be plugged into the top of any PSU module.. Is This what you refer to? The board itself a self check, or built in bios, if anything fails, you will see red 45 led. I actually had my secondary board up for an hour, power stepped it 10 times, and turned the power off to see if other core would hit, and lost it. I have since pulled the board and low and behold, I have oil under the board. A slow leak from the front pump. I am cleaning as we speak, and will not plug it back in till my liquid pro is here tmw. If I do not figure out the pump leak, I will dunk this bitch in mineral oil and fire it.
