I wanted build 48v DC power from 4 12v power supply units. Eventually i got my hands on Lite-On PS-2122-8L1 server psu. But after getting it, i am still unable power it on with out chassis. i mean i dont have a server, But i want to power it for my battery projects and also to smart chargers to deliver high power.

i tried shorting,adding resistor to pin 33 and one more pin which is soldered, like for HP psus but i think this has 8 small pins both top and bottom. Top Pins Bottom Pins

So anybody can help me power this thing up. Or can provide output connector pinouts, Circuit diagram etc., anything related which helps me in powering this PSU.

I have attached some pictures of the power supply. Let me know aything related to it. enter image description here enter image description here [enter image description here5 enter image description here enter image description here

Thank you all..
