HS0550
We have approximately twelve 75A @ 12V power supplies that came from a rackmount Hitachi Data Systems RAID array.
Here in the UK, they are found most often in HP XP20000/XP24000 data storage arrays as well as other Sun (StorageTek) OEM arrays like the 9985V based upon the HDS Universal Storage Platform V. You will often find them referred to under the part number 5529219 or 5529219-A.
To turn on: short pin 2 (should measure 4.6v) to ground on the first block.
This page documents what we know about these systems.
Looking at the back of the PSU, with connectors at the bottom, looking from the back, from left to right, labeled on the PCB:
J01 J02 J03 J04 J05
each connector is 6 pins, pin 1 is top right, 2 is bottom right:
5 3 1 6 4 2
I may have 3 and 4 confused on some connectors!
[A] almost certainly gnd (also present on the black wire on the fans),
these pins are a bit longer and so make contact first.
[B] probably +12V ~270ohms to B
J01
1 medium [A] 2 medium * 3 thin * 4 thin * 5 thin * 6 [A]
J02
1 [A] 2 [B] 3 [B] 4 [B] 5 [B] 6 [A]
J03
1 [A] 2 via cap to A -> ? * 3 [A] 4 alpa 0 5 alpa 1 6 [A]
J04
1 [A] 2 [B] 3 [B] 4 [B] 5 [B] 6 [A]
J05
1 [A] 2 thin -> dip 1 (dku id) 3 thin -> dip 2 (box id-0) 4 thin -> dip 3 (box id-1) 5 -> diode resistery stuffs * 6 [A]
* these pins need further investigation.
mini board
This is the little pcb at the back of the psu's with the 2 led's, a switch, and 5 dip switches on it.

here is a thing that i dug up
