Mac Mini M1 Mod to Receive Power over Ethernet Instead of the AC Input

Surely they're all 'up to'? It's not 'you must sink this much current or else not compliant'?

It seems like a weird thing for TFA to say anyway - my PoE[+] switch was the cheapest 8 port I could get a few years ago on Amazon, and does 30W per port. I don't really understand how you could look into it at all, be willing to attempt the hack, but not use a switch (or injector or whatever) that's capable of powering it under load.

Hah, yes they are all 'up to' on the device side. A switch port or injector is not compliant with a particular standard if it does not provide for the type-specific load, however.

Depends. Within the standard, you can do 51w at the full 100m on standard cat6, which is 300ma/pair. If your runs are shorter, you should be good to go at the full type4 current, or, 960ma.

This is a good reference for this: https://www.5gtechnologyworld.com/what-every-engineer-should... which goes into how to calc your total bundle dissipation and whatnot.
