TP-LINK TL-SG1218MP V5.0 18-port Gigabit switch with 16-port PoE+ port

The TL-SG1218MP V5.0 is a powerful 18-port Gigabit switch designed for networks that require high reliability, scalability, and PoE+ power delivery. The switch includes 16 PoE+ Gigabit RJ45 ports with a total PoE budget of 250 W, allowing direct powering of IP cameras, access points, VoIP phones, and other 802.3af/at devices. Two additional Gigabit RJ45 ports and two combo SFP slots allow for flexible network upgrades with fiber optic connections.
A switching capacity of 36 Gbps and packet forwarding at 26.78 Mpps ensure stable data transfer even in busy networks. Advanced features such as 802.1p/DSCP QoS, automatic MAC address learning, Flow Control, and PoE Auto Recovery enable efficient management and high availability. Extend Mode on ports 1–4 enables data transfer and PoE power supply up to 250 m, while Priority Mode and Isolation Mode enable traffic optimization and greater security.
The switch is equipped with two fans for reliable cooling and allows rack-mount installation. It is compatible with various types of UTP/STP cables and supports jumbo frames up to 10 KB. The device is suitable for professional networks in offices, surveillance systems, or infrastructure deployments where high PoE budgets and stable gigabit connectivity are required.
