Would anyone who has actually set up a rack assume that they meant these racks were wireless with a self-contained nuclear generator?

I think their description conveys what it does just fine for the target audience.

Yes, those are two different things.

To be super clear about it, this is referring to not needing to cable up all of the individual sleds to the rack upon installation. It doesn't mean that we recommend connecting a rack of compute to your data center via wifi.

Cdchn was hoping that it had a Starlink antenna built into the rack. :)

and solar panels!

Wait, these things are weather proof, too?!!

They mean no intra-rack cables, which are the overwhelming majority of cables on a typical rack.

This is pretty big, as someone who has deployed servers to datacenters before. Remote hands are very good at plugging in the network uplink and the PDUs. Doing a complete leaf-spine 25GbE network with full redundancy is something they are pretty much guaranteed to screw up at some point.
