    The below information is from the EVM's User Guide:

    Section 2.3 Powering Off EVM

    The proper procedure to power down the board is as follows:

    1. Use software to gracefully power off (for example, in Linux, use the "poweroff" command).

    2. If unable to use software (for example, software has crashed or does not have a shut down command), press the power button for at least 15 seconds until the power LED (D3) turns off.

    3. If you need to remove the DC power jack: (a) Follow above steps to gracefully power down the board. (b) Disconnect AC power cord from the power brick. (c) Wait several seconds until the DC LED (D41) turns off (the power brick discharges its voltage). (d) Disconnect DC barrel of power brick from the board's DC jack.
