T48S used with power adapter AND POE
Hi!
To lower the charge of our POE Switch I connected a DC power adapter DC 5V (not original but with the right voltage) with the T48S. Since then there is only the red light permanently on without any further function.

Did I convert my device the quickest way to e-rubbish?

Thanks a lot and happy new year to the IP specialistst!

Jürgen
