This PoE switch has 4 10/100Base-TX Ethernet ports, 1 10/100/1000Base-T Ethernet port and 1 1000Base-X SFP slot, of which port 1-4 support IEEE802.3 af/at PoE(Power over Ethernet) protocol power supply. The PoE port supports a maximum output power of 25.4W, and the maximum PoE power output of whole machine is 65W; It is support standard PoE protocol, which can automatically detect whether the powered device supports PoE power supply, and it only provide the power to the same PoE protocol PD devices, it can effectively prevent damage to non-PoE powered devices.
