38kW ~= 50 HP ~= 45A at 480V three-phase, which is a relatively light load handled by 3#6 AWG conductors and a #10 equipment ground.

I mean, it’s a shitload more power than a simple media converter that takes in fiber and outputs to a RJ-45 but not all that much compared to other commercial electrical loads. This Eaton/Tripplite unit draws ~40W at 120V - https://tripplite.eaton.com/gigabit-multimode-fiber-to-ether...

A smallish commercial heat pump/CRAC unit (~12kW) can handle the cooling requirements (assuming a COP of 3)
