To my knowledge the GL.iNet AR300M16 hardware does not support PoE power -- it must be powered with 5v microUSB.
The GL.iNet models that do support PoE only support IEEE 802.3af -- this means they require 48v on their WAN port from a 802.3af compliant switch or injector. However, only specific models have PoE support -- only the ones that have a PoE module installed on their pcb. You either need to purchase it pre-installed directly from GL.iNet or buy the PoE board and solder it to the pcb yourself. You need to check the GL.iNET documentation for information on this feature -- example link included.
