HP power supply mod DPS-1200FB-1A HSTNS-PD19

I have them all spot on at 13.80 volts. Now, these supplies include load sharing and I can't find the pin out. I want to let the supplies communicate with each other to share the load, and all I have found is a thread somewhere saying that the load share pin is the fifth pin, bottom of board, and just connecting them together with the other load share pin is all that's needed. I'm skeptical.

Edit, it seems the load sharing function is handled by the server and not the supplies, I thought so.

Should I use high current diodes on the outputs of each supply to prevent back feeding?

I recently replaced toshibas with HG pills in my x-Force straight 10 pill. I removed the original unregulated power supply as the HG are sensitive to voltage swings. Planning on stacking 3 of these to replace the unregulated supply. They are dozens of different versions out there. This is the only thing I could find on the PD19 version.

Also look at and check the description for a link to schematics of the areas of change.
