Yes. A supply and return line along with power. Though if I had to guess how its setup this would be done with some super slick “it just works” kind of mount that lets them just slide the case in and lock it in place. When I was there almost all hardware replacement was made downright trivial so it could just be more or less slide in place and walk away.

You can see the male quick disconnect fittings for the liquid cooling at each corner of the server in this photo:

Looks like the power connector is in the centre. I'm not sure if backplane connectors are covered up by orange plugs?

it's not the center one, it's the side ones. Center seems to be a power supply.

Interestingly, entire supercomputers have been decommissioned [1] due to faulty quick disconnects causing water spray.

So you can get a single, blind-mating connector combining power, data and water - but you might not want to :)

Maybe similar to a gasoline hose breakaway

Non-spill fluid quick disconnects are established tech in industries like medical, chemical processing, beverage dispensing, and hydraulic power, so there are plenty of design concepts to draw on.
