PE082-120-C is an advanced PoE switch providing a network point for data transmission and power supply. It has 8 PoE ports that can provide standard IEEE802.3af/at power supply through network cables. Because of the advanced self-sensing algorithm for supplying power over IEEE802.3af/at, the connected PoE or non-PoE standard equipment is safely protected. FEATURES  .8*10/100M RJ-45(POE)+2*10/100M RJ-45  · Conforms to IEEE 802.3, IEEE 802.3u and IEEE802.3af/at ·  The max. PoE power output is 15.4 W (IEEE 802.3af )/ 30 W (IEEE 802.3at)  · 250 meters of PoE transmission distance of power and data (Cat 6 )  · MDI/MDIX self-adaptation  · Store-and-forward switching  · Lightning protection
