Plug and play

This PS28-2422-SFP switch provides a network point for power supply and data transmission. All the 24 POE ports can be connected with 10/100Mps quickly, and the uplink port is 1.25Gbps fiber interface, among which 1-24 ports can provide standard IEEE802.3af power supply. Due the advanced self-sensing algorithm supply power for IEEE802.3af terminal unit only, 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. In short, The PS28-2422-SFP features simple and reliable design, automatic identification POE requirements, duplex and high-speed.


This cost-effective PS28-2422-SFP provide network layout need to simplify wireless access point (AP) and IP-based surveillance cameras network cameras in order to install in commercial network and home network. The devices far away from power socket are very suitable for hanging on the wall or ceiling. POE eliminates the need for connecting these devices to power socket. So it make more flexible for those difficult to connect with AC power socket, and cut down the installation cost. It is ideal choice for those want to deploy a small commercial network and home network that use wireless access point (AP) and IP-based surveillance cameras.
