Features: 1.8x1000M PoE: This PoE switch provides 8 x 1000M PoE port, 2 x 1000M Uplink port and 2 x 1000M SFP port. Each PoE port provide up to 30W, a total PoE budget of 150W. 2 Gigabit Ethernet uplink ports for connecting to NVR and Internet, etc. 2.Fanless Design: This 10 port PoE switch supports plug and play, easy to setup. Fanless design makes the poe switch work without any noise. Network cable short circuit protection mechanism protects faults caused by network port short circuits. Short circuit, over current, over voltage protection. 3.802.3af/at Compatible: This 10 port PoE switch supports 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 device needs to be powered separately. 4.Extension Mode: When the extension mode is enabled, the transmission distance of the POE port can be extended to 250m at a rate of 10M. 5.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. specification:Item Type: PoE Switch Material: Aluminium Alloy Downlink Port: 8 x 1000m Poe Port.
