Intellinet 5 Port POE (Power-over-Ethernet) Gigabit Switch with 68 Watt POE Power Budget and PassthroughThis versatile POE switch can be used 2 ways: you can connect it as a regular 5 port POE switch using the included power supply for a 68W power budget or you can connect it to a 30W POE+ ethernet line to use this as an extender and a 4 port switch. When used as a extender it draws 4W of power from the POE ethernet line, leaving 26W of POE power (assuming you use a 30W per port POE switch or 30W injector as the supply power) for the remaining 4 ports. This allows the connected devices to be able to have an additional 100m (328ft) of cable from the switch as well. Number of Ports: 5x RJ45 (8P8C) POE Ports: 4x RJ45, 30w Max per Port, 68W Power Budget (Using Included Transformer) POE Protocols: IEEE 802.3at/af Ethernet Speed: Auto-Sensing 10/100/1000 Mbps Duplex Speeds: IEEE 802.3x Flow Control for Full Duplex Dimensions: 5.5" x 3.1" x 1.1"
