The TP-Link Omada SG5428X is a high-performance 24-port Gigabit L3 managed switch designed for the access layer of medium-sized and more demanding business networks. It is equipped with 24 × Gigabit RJ45 ports and 4 × 10G SFP+ slots, enabling high-speed uplinks to servers, aggregation switches, and other network segments. The total switching capacity is 128 Gb/s, and the forwarding rate is 95.23 Mpps.

A key advantage of the SG5428X is its support for physical stacking of up to four units. All four 10G SFP+ ports can be used for stacking, with a total stacking bandwidth of up to 80 Gb/s. This makes it possible to connect multiple switches into a single logical infrastructure with higher availability, redundancy, and easier management.

The SG5428X also offers a rich set of Layer 3 features, including static routing, RIP, OSPF, DHCP Server, and DHCP Relay, allowing it to handle some of the routing tasks in a business network. For greater availability, it supports ERPS (Ethernet Ring Protection Switching), and for security, it supports 802.1X, MAB, ACL, Dynamic ARP Inspection, Port Security, DoS protection, and Secure Shell. Integration with Omada SDN enables centralized management, Zero-Touch Provisioning, network monitoring, and bulk device configuration.

The TP-Link Omada SG5428X is an excellent choice for medium-sized businesses, large offices, hotels, schools, and service providers that require a combination of a large number of Gigabit ports, 10G uplinks, and advanced Layer 3 features is required. It is particularly appealing in scenarios where a modular network architecture is desired, as stacking up to four units allows for gradual infrastructure expansion without replacing the entire access layer.
