Please make sure that all the main board components are connected correctly and then connect the power adapter to a plug with power supply. After that, connect the power adapter to the board. The board will automatically power on for the first time connecting to power. After power on the whole system, you can turn off the system via the command poweroff. And then you have two ways to power on the Firefly-PX3-SE:
