Hey, folks,

As a part of my continued repair work on my Onyx2 deskside, I just picked up a pair of node boards from Raion. (Thanks again! ) However, after installing them, I was still getting general exception errors from one of the boards, and I can't get it to boot fully with a single board installed, either.

After disassembling everything again, I found that the midplane is actually missing two SMD components that look like either capacitors or perhaps a resistor pack. It wouldn't surprise me if this was the cause of my current woes. The two that are missing are labeled as R1F0B and N4E4B on the board. Both are located in clusters with others, on the side of the board with the power connectors. The areas are above the two white power connectors, close to the large group of big electrolytic capacitors.

I'm hoping that someone might be able to identify the ratings of these parts from their own midplane, so that I can obtain replacements. There are enough different parts around the board that I can't really guess exactly what they should be and just winging it seems like a bad idea.

I've attached two pictures showing the missing components and the ones surrounding them.

Thank you!
