I have a Astec DS550-3 that is out of warrenty with SUN and it has had problems but seems to still work.. I got a new replacement for the server and would like to turn this into a bench PS. I have done this a lot on ATX PS's but I'm confused on this what to use as my "turn on" pins.. Here is the pinout of it according to Astec. Any help would be awsome!
