Description

TP-Link SG2428LP Managed PoE+ Switch Overview

The TP-Link SG2428LP is a managed PoE switch from the Omada series featuring 28 Gigabit ports, designed for stable enterprise and deployment environments where reliability, security, and centralized administration are critical. The device combines 16 PoE+ RJ45 ports, 8 non-PoE RJ45 ports, and 4 Gigabit SFP slots, optimized for connecting IP cameras, access points, and VoIP phones in a compact, rackmount chassis. With a total PoE budget of 150 W (up to 30 W per port), the switch meets typical requirements for medium-sized networks without external PoE injectors. The fanless design ensures silent operation, while the metal housing provides durability for continuous 24/7 use. Omada cloud management offers centralized configuration, zero-touch provisioning, and monitoring via web, mobile app, and controller (hardware, software, or cloud). It supports L2/L2+ features such as VLAN, QoS, IGMP Snooping, Link Aggregation, STP, static routing (IPv4/IPv6), DHCP Server/Relay, DLDP, and Mirroring for precise traffic control. Built-in security mechanisms include 802.1X, IP-MAC-Port Binding, DHCP/ARP/ND protections, DoS defense, Port Isolation, and ACL policies with up to 230 rules. Management is flexible through the web GUI, CLI (telnet/SSH), SNMPv1/v2c/v3, RMON, dual image/config, and cable diagnostics for fast troubleshooting. The combination of PoE+ ports, Gigabit switching with SFP, Omada cloud management, and a silent, fanless design makes it an excellent choice for offices, schools, hotels, surveillance systems, and Wi-Fi infrastructures.
