Item Type: 5 Port Gigabit PoE Switch Material: Aluminum Alloy Plug Specification: EU Plug 100-240V Downlink Port: 4 x 1000m POE Port, Transmission Distance: 100m Uplink Port: 1 x 1000m Uplink Port, Transmission Distance: 100m SFP Port: 1 x 1000m SFP Port POE Standard: IEEE802.3af or at Power Supply: 52V 78W (built in Power Supply) POE Type: 8 Cores, Full Core Protection Level: 1 Class, Common Mode, 2000V Lightning Protection1,5 Ports: 5 port Gigabit PoE switch with 4 1000M PoE ports, 1 1000M uplink port, 1 1G SFP, 4 PoE ports, each port is up to 30W, and the total PoE budget is 78W. 1 Gigabit Ethernet uplink port for connecting NVR and Internet etc. 2,VLAN Mode: Gigabit PoE switch supports VLAN mode (open VLAN switch) and supports 4 PoE ports to be isolated from each other. This 4 port PoE switch is easy to manage and maintain, prevent broadcast storms, prevent data confusion, and make wireless networking application data more stable. 3,802.3af or at Compliant : 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. 4,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 don't need power, the switch will not power those devices and won't damage the device. 5,Plug and Play: The PoE switch is easy to install and requires no software installation or configuration. Built in power supply, the power supply is located in the poe switch body, integrated with the switch, and when connected to our AC power cord, the switch can transmit power to the devices connected to the switch.1 x 5 Port Gigabit PoE Switch 1 x Power Cable 1 x User Manual
