buy Switch TP-Link TL-SG3428MP 24xG + 4xSFP . The TL-SG3428MP from TP-Link is a managed switch designed for network environments requiring high performance and flexible PoE (Power over Ethernet) power supply. It offers 24 Gigabit PoE+ ports compatible with 802.3at/af standards, delivering up to 30 W per port and a total maximum power of 384 W, enabling simultaneous connection and power supply for multiple devices such as IP cameras, VoIP phones, and wireless access points. Additionally, it features 4 Gigabit SFP slots for fiber optic links, expanding high-speed connectivity options. Its switching capacity of 56 Gbps and forwarding rate of 41.66 Mpps ensure efficient data traffic handling, suitable for medium and large networks. This model includes advanced centralized management functions through the Omada SDN platform, allowing zero-touch provisioning (ZTP), cloud management, and intelligent monitoring, simplifying administration and enhancing network visibility. It also supports static routing, optimizing internal performance and traffic distribution. For security, it provides multiple robust mechanisms such as per-port IP-MAC control, access control lists (ACL), 802.1X authentication, DoS defense, storm control, and RADIUS authentication, protecting the network from unauthorized access and attacks. Quality of Service (QoS) is managed via L2/L3/L4 prioritization and IGMP snooping, optimizing latency-sensitive voice and video applications. Management access is available through web interface, CLI, SNMP, and RMON, along with dual firmware images ensuring operational continuity. Designed for rack mounting, it measures 440 x 330 x 44 mm and weighs about 3 kg, with a black finish and sturdy construction for professional IT environments. It includes dual fans for efficient cooling and power consumption ranging from 34.4 W without PoE load up to 465.8 W with all ports active. In summary, the TL-SG3428MP switch is a robust and versatile solution for network infrastructures requiring a high number of PoE ports and advanced management, combining performance, security, and ease of administration for demanding business environments.
