Features: 1.6 Port PoE Switch: 4x1000Mbps PoE ports (802.3at/af) and 2 x 10Mbps 100Mbps uplink, the power budget of each PoE port is up to 30W, and the overall power budget is 78W. 2.Versatile: Plug and Play: The 6 port unmanaged network switch supports auto detection of devices and is easy to set up with no software installation or configuration required. Fanless Design: The fanless design makes the poe switch work without any noise. Network cable short circuit protection mechanism: POE switches are stable and have strong anti interference ability to protect faults caused by network port short circuits. Short circuit, over current, over voltage protection. 3.Active Poe Switches: Poe switches support poe devices and non poe devices, but when connecting passive poe devices or non poe devices, the switch can only transmit data and cannot supply power to your devices, so the connected devices need to be powered separately. Alternatively, you can use it with an active poe splitter. 4.Extended Mode: When the extended mode is enabled, the transmission distance of the POE port can be extended to 250m at a transaction rate of 10M. 5.AI PD Detection: The poe port will intelligently determine whether the device connected to the port needs power supply. In the case of non poe devices that do not require power, the switch will not supply power to those devices and will not damage the device. specification:Item Type: PoE Switch Material: Aluminum Alloy Plug : EU Plug 100-240V Downlink Port: 4x1000M PoE Port, Transmission Distance: 100m SFP Ports: 2x1000M SFP Ports POE Port Maximum Power Output: 30W Power Supply: 52V 78W (Built in Power Supply) POE Type: Terminal Jumper Method (1/2+, 3/6-) Support: IEEE802.3af/at V Lightning Protection PackageList: 1 x Switch 1 x Power Cord 1 xUser Manual
