Don´t fight guys, please. :))

I´ve found more info, I only had to read the sticker on the back of the
enclosure. It reads
"48V DC. 62.5 AMPS max per shelf. Dual circuits (A+B) for redundancy"

The dual male plugs marked "POWER CIRCUIT A" and "POWER CIRCUIT B" means
exactly that. The Beast has two independent 48V DC imputs, for redundancy.

But the positive and negative on each of the two not marked AT ALL and it
seems to me that the male round plugs protuding are totally reversible
(!?), so there´s a big possibility of frying everything if I get polarity
backwards...

Oh, Dear God of HP blades, we invoke you...
Maybe on the BSD lists they´d have a clue?.
