Hello @stehardy,
welcome to the Polycom Community.
Telling us a little bit about the history of a device may help us suggesting solutions.
Is this a brand new unit or a used unit that work prior?
The PoE comparison only tells us that the cable supplies power to the unit but the network park behind this may be fried.
I suggest you RMA the unit if still in warranty.
Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.
Best Regards
Steffen Baier
