try only powering the side with the ethernet so only use 1 pcie hook up and pull the white ribbon that links to the second board.
If that works. do the same with the ribbon attached. if that works then the board with no control card is the issue.
Thanks for the response. So far it looks like the LAN card side power is the problem. I can plug in the other blade and it doesn't blow the psu off. But as soon as I would plug into the LAN side, it shuts off the power. I never even get a LAN light, just instant trip. At this point, I'm thinking I now have something to rob parts off of in the future.
