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

Have not seen this mentioned anywhere else so I'll add: this is a "board edge connector". A whole PCB will plug into this socket, rather than a plastic connector on the end of some wires.

Picture plugging a graphics card into a socket on a motherboard. It's that type of connector. The PCB it will plug into will have exposed metal pads on a bit that juts out.

You are correct! I did get a reply from sonnet and there is a set of 2 fans I didn’t see in the case when I posted. This board plugs into their controller board when the inner case is slid into the outer case
