1pcs PoE injector Splitter & 1pcs 8-port POE hub To achieve best performance of a Wireless LAN, the location of Access Point(AP) must be carefully chosen.In most cases, finding a power supply for AP is a common obstacle. Power over Ethernet(PoE) technology provides the perfect power Usage1:wall mount adapter of poe power 4/8 LAN ports,4/8 LAN and power ports,Power VOIP phones,IP cameras,WiFi access points,and so on Same voltage to all ports,power is shared equally 2.1 x 5.5 mm for DC plug LED power light.Works with any Ethernet switch or router Uses 48 V power adapter to output 48 V power supply solution to help overcome these obstacles.In Ethernet, four pairs of C5 or C5E twisted pairs are used as the medium for transmission. The actual data transmission, however,only takes up 4-pairs of wires (pairs 1-8). PoE technology utilizesthe remaining pairs(pairs 4-5 and 7-8 to conduct electricity. Data PIN:1/2,3/6 Power PIN:4/5+ and 7/8- Data in:Connects PC/HUB/Switch Ethernet Data rate:10/100 Mbp Ethernet Cable:TIA/EIA 568 Cat.5 Ethernet Cable Connector:RJ-45 Operating Temperature:0- 40 Degree Storage Temperature:-40-70 Degree Operating Humidity:10%to80% RH Storage Humidity:5%to90% RH Note this one is for 10M/100M,without adapter, with out earthnet and power connectiong cables.
