Can Airlive / Airmax wireless devices be powered by a PoE/PoE+ switch?
Unfortunately Airlve / Airmax products cannot be powered by PoE or PoE+ switches.
Are you sure, they do say the are powered up the Ethernet cable?
The Airlive / Airmax products are passive 12v PoE products meaning Airlive / Airmax products do not support 48V, 802.3af standard PoE or PoE+. Please use the PoE kit that is provided in the package which requires a 12v plug top PSU to power the equipment.
