The TL-SF1008P 8-port 10/100M Desktop PoE Switch provides the seamless network connection. It integrates 100Mbps Fast Ethernet and 10Mbps Ethernet network capabilities. 4 of the 8 Auto-Negotiation RJ45 ports (port-1 to port-4) of the switch support Power over Ethernet (PoE) function. These PoE ports can automatically detect and supply power with those IEEE 802.3af compliant Powered Devices (PDs). In this situation, the electrical power is transmitted along with data in one single cable allowing you to expand your network where there are no power lines or outlets, where you wish to fix devices such as APs, IP Cameras or IP Phones, etc. TL-SF1008P has the priority * function which will help protect the system when the system power is overloaded. If all PoE PDs power consumption is >= 53W, a priority will be arranged among the PoE ports, then the system will cut off the power of the lowest-priority port. TL-SF1008P is easy to install and use. It requires no configuration and installation. With desktop design, outstanding performance and quality, the TP-link TL-SF1008P 8-port 10/100M Desktop PoE Switch is a great selection for expanding your home or office network.
