ac lite connecting to router resets ac lite

I flashed my ac lite with 3.25.2.0 and can create a mesh connection with my ac3, but when I plug the ac lite into my home router (using port 1 here from https://downloads.arednmesh.org/snapshots/readme.md and https://arednmesh.readthedocs.io/en/latest/arednHow-toGuides/home-router... ) the ac lite gets hot and turns both LEDs off, which made me worried about some electrical fault.

I don't think my router does passive PoE, has anyone seen something like this?
