Yeah, running in colo has another constrains than running a homelab. In my case, a switch with appropriate amount of slots was just few Us above, for free ;).

What I was wondering, why unmanaged switch without PoE (OK, I then it would need additional IP address), no PoE hats and then having to play around with relays (their control doesn't require IP?). With PoE managed switch, you would get control of PoE and could turn off/on the Pis.
