TP-Link model: SG2218P
The TP-Link Omada Smart Switch SG2218P V2 is an 18-port Gigabit switch designed for enterprise deployments that require PoE power and centralized smart management. It features 16 802.3af/at PoE+ ports with a total budget of 150 W and up to 30 W per port, allowing you to power access points, IP cameras, VoIP phones, and other converged network devices. Its 2 Gigabit SFP slots offer fiber optic connectivity for high-speed uplink links. With a 36 Gbps switching capacity and a 26.78 Mpps forwarding rate, this store-and-forward architecture switch integrates L2+ static routing, full VLAN support (up to 4K groups), 8-queue QoS, ACLs with up to 230 entries, and 802.1X security with RADIUS authentication. Fully integrated with the Omada SDN platform, it enables centralized cloud management via hardware, software, or cloud-based controllers, Zero-Touch Provisioning (ZTP), and intelligent multi-site monitoring, all in a 440 mm (17.3 in) rack-mountable metal fanless housing.
