TEF1109P-8-63W is an 9-Port 10/100Mbps Desktop Switch With 8-Port PoE developed by Tenda. It provides 9 10/100 BASE-TX RJ45 ports. Ports 1-8 support IEEE 802.3at PoE standard with each port providing power of 15.4W, or support IEEE 802.3af PoE+ standard with each port providing power of 30W. The whole device can provide power of up to 58W. By using CAT5 twisted pairs, it can provide power and data transmission to APs, IP cameras, IP phones, and so on. In addition, all the port s support lightning protection of 6kV and long distance data transmission and powering of 250m, which decreases deploy ment difficulty and time thus decreases cost.Lightning Protection 6kV The ports and embedded power can provide lightning protection of up to 6kV. It also provides PSE shortcircuiting protection, PoE overloading, power over temperature, over voltage and surge current protection. Outstanding PoE Power Supply Ports 1-8 support IEEE 802.3at and IEEE 802.3af PoE standard. It provides 30W maximum PoE output a single port and 58W the whole device. 250 Meters TransmissionWith 8-pin and the professional network extension technology, the transmis- sion distance of power and data can be up to 250 meters, which can work in place of network extender or some optical fiber to expand the network without additional cost.
