Accessing the video requires signing in, so it isn’t available. You can attach files to your existing post…hover the mouse over the quote mark in the upper right and a few icons appear. The paper clip icon allows you to attach a file to the existing message. There are limitations on file type allowed (not sure what they are), so you might end up having to just show a jpg of the one light.
In the meantime, there are two LEDs which should light up. They are right next to the power button on the carrier board (I think one is indication of power for the carrier, the other is likely an indicator of power to the module itself). Ethernet of course has its own lights, but other lights on the carrier board are probably an error.
