The Netis PE6108H Fast Ethernet Poe Switch is a great selection for expanding your home office or small office network. Only 4 of the 8 10/100 Mbps RJ45 ports of the switch support Power over Ethernet (15.4W x 4) function. It can automatically detect and supply power with the IEEE 802.3af compliant Powered Devices (PDs), like Poe APs, IP cameras, etc. In this case, the electrical power is transmitted along with data in one single cable allowing you to expand your network to where there are no power lines or outlets.
