Solution:

Disconnect or turn off the power supply. Press the OEM reset (factory reset) button. (NOTE: This may require the use of a small narrow object, it is important that this object is not sharp as it may cause damage to the unit.) While holding the OEM button pressed reapply power to the unit. Hold the OEM reset button for 5-6 seconds after power has been applied. Release the OEM reset button. The device will restart with the installed OEM defaults. If no OEM Configuration is applied the device will return to B&B Electronics factory defaults. NOTE: The location of the OEM reset button for the Enterprise devices is on the back of the enclosure, underneath the label near the pigtail. The Industrial devices OEM reset button is on the Ethernet/Power end of the box next to the 2.1mm barrel connector.
