Connect desktops, printers, access points, servers, and other wired devices through 24 Gigabit RJ45 Ethernet ports while reserving four Gigabit SFP interfaces for fiber uplinks. The TP-Link Omada SG3428 provides a 56 Gb/s switching capacity and 41.66 Mpps forwarding rate for a full Gigabit access layer. Its 1U rack-mountable chassis uses passive cooling, avoiding fan noise in network closets, offices, and equipment rooms. Layer 2 and Layer 3 services support segmented business networks with link aggregation, IGMP snooping, IPv4, IPv6, strict-priority queuing, and weighted round robin scheduling. A 16,000-entry MAC address table and support for 9,000-byte jumbo frames suit environments that need efficient switching between many local devices. The micro-USB port provides local access, while Omada centralized management supports administration of connected network devices. Network protection features include ACL support, DHCP snooping, storm control, DoS attack prevention, and RADIUS authentication. These controls help administrators limit unwanted traffic, validate DHCP activity, and apply access policies at the switching layer. The internal power supply accepts 100 to 240 VAC input, and maximum power draw is 19.9 W. This model does not support switch stacking, making it appropriate where a standalone managed access switch with copper edge ports and fiber uplinks is required.
