The silence of the racks is deafening, production gear has gone dark – so which wire do we cut?

Re: The big red button

I looked for it recently and could find no evidence of it ever existing, but I'll swear blind that it did. Or I'm insane, one of the two.

I think it existed. I recall finding some of the packs somewhere, interest drawn by that they clearly went into drive bays but were not drives. I also recall someone having a couple of very tall tower cases with more drive bays than could possible be filled even with 3 mobos in the case (which I am sure it could fit!), and being told it was for internal UPS.

Really all you need to do is have the mains go into a charge controller that keeps the batteries topped up, then another circuit off the batteries that runs the internal voltages. Maybe I have a new weekend project...

(Or just get a decent laptop which comes with its own inbuilt UPS anyway :) )
