【18 Ports Full Gigabit PoE Switch】The SICSOLINK 18 Ports Gigabit Ethernet PoE Switch include 2 gigabit uplink ports and 16 gigabit RJ45 ports, all ports can provide up to 1000 Mbps speed.The 2 gigabit uplink port are used to connect to NVR, other switches, routers so that you can get real 16 Ports PoE Switch. | 【POE Switch】Support IEEE802.3af/at PoE standard, the switch can provide power and data to your PDs at same time,which is more convenient and save more cable.The total output power on 16 PoE ports up to 250 W meanwhile the maximum power of each port is 30 W,enough for the most PDs. | 【Plug and Play】Plug and Play, easy setup with no software installation or configuration needed. | 【4KV Lightning Protection & VLAN Mode】This PoE switch has 4KV lightning protection for safe use in any weather. It’s One Key VLAN mode isolates ports 1-16 to prevent interference between them, maintaining communication with uplink ports. Unlike traditional mode, where a 100Mbps device can slow other ports, VLAN mode prevents this. If one port fails, others remain unaffected, improving both security and reliability. | 【Convenient Design】Fanless design ensures quiet Operation;Metallic Housing Design, fast thermal conductivity for efficient cooling, and extended equipment lifespan. | 【Commitment and Tech Support】Every PoE switch is rigorously tested for reliability, quality, and performance. And we promise it can work well at least one year.If you have any problems,please email we, our technicians will repley your email within 24 hours.
