When pressing the reset button on a controller or SIO, you are sending a software reset to the board. The software reset is not a graceful shutdown, it will terminate all processes immediately. When a board does not have a reset button it is recommended to pull the terminal block or POE cable. It is not recommended to pull the jumper that distinguishes between a 12V or POE connection.
Boards that do not have a reset button:
1. LP1501
2. MR62e
