Features 1、4 or 8 enough channels meet the need that you are lacking of the ports. 2、POE power supply module is compatible with all IEEE802.3af network devices, but it does not have auto-detection function. 3、LED power light allows you to clearly know the working status. 4、Same voltage to all ports, share available power equally. 5、High stability and outstanding performance. Specification Description: This POE injector ethernet adapter is a good solution for you to save you trouble in power cabling and costs by simply connecting your POE or non-POE device with an Ethernet cable. This POE power supply module is compatible with all IEEE802.3af network devices, but it does not have auto-detection function. As long as they are connected, they can directly supply power to network devices. Features: 4 or 8 enough channels meet the need that you are lacking of the ports. POE power supply module is compatible with all IEEE802.3af network devices, but it does not have auto-detection function. LED power light allows you to clearly know the working status. Same voltage to all ports, share available power equally. High stability and outstanding performance.
