ESP32-POE: Deactivate POE?

[charno]

Hi,

For a Project I'm powering the ESP32-POE (Rev. i) with external 5V supply (not by USB but on the 5V PIN). Since I need Ethernet I think it's necessary to disable POE functionality to prevent damage if someone plugs the board into a POE powered Ethernet port.

Questions:
- Is it correct that the board or the power supply will be damaged if 5V supply (on the 5V PIN) and POE power is applied at the same time?
- Is there an easy way (good to reach component, easy to cut trace) to deactivate POE?

Thanks in advance

- Yes, quite likely and I would not recommend. Consider ESP32-POE-ISO instead, if you need such connection.

Is there an easy way (good to reach component, easy to cut trace) to deactivate POE?

- No. 50V+ are not a joke. You can deactivate it via software means at your network equipment.
