1、6 Ports: This gigabit PoE switch provides 4 x 1000Mbps PoE ports(802.3at/af) and 2 x 10/100Mbps uplink gigabit ports, the power budget of each PoE port is up to 30W, and the overall power budget is 78W. 2、AI PD Detection: The PoE port will intelligently judge whether the device connected to the port needs power. If it's a non PoE device that doesn't require power, the switch will not power those devices and won't damage the device. 3、802.3af/at Compliant: This 6 ports PoE switch supports poe devices and non PoE devices, But when connecting passive PoE device or non PoE device, the switch can only transmit data and cannot power your device, so the connected device needs to be separately powered. 4、Strong Anti Interference: This gigabit PoE switch with short circuit protection mechanism features stable performance and strong anti interference. Protecting faults caused by network port short circuits. Short circuit, over current, over voltage protection. 5、Plug and Play: This 6 ports PoE switch supports plug and play, auto detection of devices and is easy to set up with no software installation or configuration required. The fanless design makes the poe switch work without any noise. Item Type: Gigabit Poe Switch Material: Aluminium Alloy Downlink Port: 4 x 1000m PoE Port. Transmission Distance: 100 Meters / 109yd SFP Port: 2 x 1000M SFP Port Maximum Power Output of PoE Port: 30W Power Supply Power: 52V 150W (Inbuilt Power Supply) PoE Type: Terminal Jumper Method (1/2+, 3/6-) Support: IEEE802.3af / at V Anti Thunder 1 x Gigabit PoE Switch 1 x Power Cord 1 x User Manual
