I'm trying to use this switch's PoE function to power TL-WA1201 V2 AP. The AP doesn't turn on any of the 1-8 PoE enabled ports. It works with its included PoE injector over the same cable. I even tested it with different cables to no avail. Does anyone know what is the reason for this? From what I researched, the PoE standards match on both devices.
