During the Zoom training I mentioned earlier, I asked the trainer whether it was OK to install both AC and DC power to a Peplink Transit. The trainer said no but didn't provide a reference. I just reviewed this thread and see some have at least tried providing dual sources of power. I did some internet research and cannot find any warnings about this either. Has anyone noticed or heard of a concern about using both sources at once? I typically always have AC available but I would like to have DC connected if I ever need it.
