Recently got a Sonnet xMac Pro Server case to put my MacPro6,1 into my rack. I’m getting things fitted into the Thunderbolt expansion housing and noticed this board with a socket on it. The board has power wired from the PSU, but there’s nothing in the manual/product details (even though it’s in the illustrations) that indicate what this connector is or what its intended purpose is. Can anyone enlighten me?
Edit: I just looked up a video of a version of this module with an outer case, for desktop use. Otherwise looks the same inside. It looks like this might provide power to 2 top-rear mounted fans. https://youtu.be/zG4I8q5JbyY?t=285&si=43mA0xhR-7ETQgPd
Considering it doesn’t have any logic and it says fanx2 I’d guess it’s a power supply adapter for 2 fans.
After finding a video for a VERY similar desktop version of this module, I’m inclined to think you’re right now. The case for putting these on a desktop does have 2 fans mounted to the top rear. Disassembly in the video does not show or indicate that they have any power cables that require unplugging.
I initially thought that, too, but I’ve never seen a fan connector like what’s on the board. Judging from the product shots and manual illustrations, the case appears to have all of its fans, and they have more direct connections to the PSU.
Not saying you’re wrong (I have no idea lol) or arguing, just how I went from thinking fans too, to doubting it.
Sort of looks like an early attempt at a hot swap connection.

-X2 could be the revision
