18 Gigabit PortsThe switch includes 16 Gigabit POE+ ports and 2 Gigabit UpLink. The ethernet ports support 10/100/1000Mbps POE and uplink connection, excellent data transmission performance. The 2 gigabit uplink can be connected to different networks or devices, such as routers, NVRs, etc. High POE PowerThe gigabit PoE switch maximum support 250W high output power, built-in power supply makes installation easier. Support IEEE 802.3af/at, each port max power supply reached 30W. *Please note: it will not supply power to passive 24V PoE and NON-PoE devices.* Extend FunctionPorts 1-16 support VLAN port isolation and cannot communicate with each other, only communicate with uplink 17 and 18 port, which can reduce network congestion, improve performance and safety. Unmanaged Plug and PlaySupports automatic detection of power supply for POE devices, port auto-negotiation, built-in power module, just connect the power cord, and connect to the device through the network cable, no
