power a s5 with 24volt psu

[gdale]

can i run 24 volt power into one hashing board of an s5 then run the ground to the 12+ input of the second hashing board  then back to the power supplies ground. will this work?

Maybe if you have them running off separate controllers. The signalling per board is common-ground 3.3V digital, so if you hook up the boards like that the controller will be tying ground to 12V and something will either trip out or catch on fire. With two separate controller boards (one for each hash board), each will be operating at local ground.

If you had two entire S5s, you could string the entire machines, which would give the controller the same ground reference for both boards (one controller and two boards at 0V, the other set at 12V).

Since ethernet uses isolated signalling the difference in ground potentials shouldn't affect the networking.

I am curious as to what motivates the question? Is this a hypothetical question, or are you really contemplating this? Part of my reason for asking is your Newbie label?

While I would always defer to sidehack electrical experience, it seems like it's just fraught with peril. One mistake and it would seem like you could seriously damage some valuable equipment.

Just my $.02.

i have a computer engineering degree and some electrical class's as while it just i have 2 24volt 2400w output power supplies. as for the label i do not stay logged in most of the time.
