Wanted - Schematic diagrams for Artesyn ( Sun V880 Server ) Power Supplies.

Just to give you guys and idea of the complexity of this project - it's nothing like what has been previously mentioned.

The daughter "control" board I spoke of has 28 surface mount IC chips ( an an uncountable number of micro chip parts as well ) within a double sided PCB that I guess is about 6 x 4inches in size - that you can only read information with a magnifier. The tracks that wire them are hair thin, maybe thinner in places.

Additional to that, there is a 48 pin 90 degree header connector joining the daughter and mother PCB's together ( yes the bastard is soldered on ) and the tracks again are hair thin.

Even with my wizz-bang new Xytronics DIA-60 De-soldering Iron ( which went out cheap at "Tricky Dicky" - Dick Smith - a few years ago ) and a new tip, I'm having great trouble just de-soldering the header connector joining the 2 boards because of the through hole plating.

Adding further insult to injury - all the the parts on the daughter PCB are surface mount - which I hate - as I can't see the bloody things without glasses and a magnifier. On the other PCbs you have about 15 large heatsinks scattered about with chip components buried underneath - meaning the heatsinks have the be removed to see the PCB wiring below. ( maybe I've lost the plot on all this and need to get a life !)

The main connector that connects the enclosed power supply module into the server has a small 24 gold pin secondary connector ( using all 24 pins of course ) back into the main server wiring. Having information on this wiring hookup will at least get the bugger to activate on the bench - before any mods can be done.

So the task of just getting the supply fired up on the bench is a challenge in itself.

The up side to all this is - the Manager of one of the US Companies I emailed, has gotten back to say "I need the service documentation" ( dah !!!) which he is looking into chasing for me ( but don't hold your breath waiting for it ! ).

If I can procure this it "might" ( I say "might" - because I'm still not confident its a plug and play setup. ) save, me a lot of grief.

I'm quite concerned de-soldering the PCB's will stuff them once and for all, because linking broken tracks is not realistic in this sort of manufacturing technology.

Anyone got any better Ideas !

( Maybe at the end of the day - I'll just go and buy a big power supply and be done with the hassle ! )

Connector Pinouts - Sun Fire X4600 and Sun Fire X4600 M2 Servers Service Manual

this is pinout for power supply SUN, but newer model then v880. But pin A1 is PS_ON - I think that is it.
