    3030* Do not hot plug any connectors or the power supply. All connections should be made with power off.
    3131* When using the JTAG adapter, make sure the development computer shares the same AC ground as the power supply being used to power the SBC to prevent ground loops.
     32* If powering from an active PoE switch, these switches use a low side FET to turn on power which means that the positive power (+) is always on and ground is switched in to complete the circuit. With this topology, if the JTAG adapter and the PoE switch are on the same ground then the board can power through the JTAG ground which can cause damage to both the board and JTAG. As a precaution, we recommend not using the JTAG with an active PoE switch.
