This BD-POE31016PF-at switch provides a network point for power supply and data transmission. All the 16 Ethernet ports can be connected with 10/100Mps quickly, and the uplink port is 155Mbps fiber interface, among which 1-16 ports can provide standard IEEE 802.3af/at power supply. Due the advanced self-sensing algorithm supply power for IEEE802af/at terminal unit, there is no need to worry about damaging proprietary PoE or non-PoE standard equipment. In addition, it will stop power supply when PoE devices are not connected.
