A PoE injector is a device that provides power over Ethernet (PoE) to a WAP or other network device that does not have a built-in power supply. A PoE injector connects to a power outlet and an Ethernet cable, and sends both power and data to the WAP. If the WAP was moved to a location where there is no power outlet or PoE switch, it would need a PoE injector to boot up. Reference: Part 3 of the current page talks about PoE and PoE injectors as a way to power WAPs. [This article] explains how PoE injectors work and how to use them.
