2- You are using the latest Raspberry Pi 3 B+ which supports POE
3- Do not touch the POE hat while operational as it will get hot, particularly when under heavy load; its designed to handle the temperatures and it will automatically shut down and reboot the temperature becomes too high.

5- Before installing or removing the Hat make sure all power sources are disconnected.
