The TP-Link Omada SG3428XMPP is a managed L2+ switch with 24 Gigabit Ethernet ports, designed for professional networks in enterprises, offices, and other IT environments. It features PoE support with 16 PoE+ ports (up to 30 W per port) and 8 PoE++ ports (up to 90 W per port), providing a total PoE budget of 500 W. This power capacity enables direct power supply to IP cameras, wireless access points, and other PoE-capable end devices via the network cable, simplifying installation and enhancing infrastructure efficiency. The PoE technology is based on the standards IEEE 802.3af, IEEE 802.3at, and IEEE 802.3bt (Type 3), ensuring compatible and reliable power delivery for a wide range of devices.

Applications
This switch is suitable for networks requiring a high number of PoE devices and centralized management. It is particularly ideal for security networks with IP surveillance cameras, WLAN infrastructures with multiple access points, and office or enterprise networks requiring a scalable and secure network architecture. The 10G support via 4 SFP+ slots enables fast uplink connections to other switches, servers, or core networks, preventing bandwidth bottlenecks.

Features and Specifications in Detail
The SG3428XMPP offers extensive management functions. It can be managed via a web-based user interface, supports cloud management through the Omada system, and allows configuration via CLI (Command Line Interface). Additional features include ARP inspection, system event logging, port mirroring, link aggregation, and broadcast storm control. The VLAN support, along with access control lists (ACL) and Quality of Service (QoS), enables precise network control and traffic prioritization. The IGMP snooping function optimizes multicast traffic, which is important for streaming or video applications.

Technology Explained Simply
The switching capacity is 128 Gbit/s, ensuring high throughput performance for data traffic within the network. The transfer rate is 95.23 Mpps, indicating the switch’s ability to process data packets per second. The MAC address table contains 16,000 entries, sufficient to manage a large number of devices in the network. The store-and-forward technology ensures that data packets are fully received and checked before forwarding, enhancing network security. The support for Jumbo Frames (up to 9000 bytes) improves efficiency when transmitting large data volumes, such as during backup or file transfers. The integrated packet buffer memory of 12 MB ensures stable processing under high data loads.

Compatibility and Accessories
The switch is equipped with 4 SFP+ module slots, suitable for installing fiber optic transceivers or direct-attach cables. Compatible modules include, for example, SFP+ Direct Attach cables (1m and 3m), MiniGBIC modules for single-mode (SM5110-LR) and multimode (SM5110-SR), as well as Omada SM5110-SR and SM5110LR modules. These modules enable flexible connections via fiber or copper, depending on network architecture and distance. The Omada SDN integration allows centralized management of multiple network devices via a cloud platform, simplifying network administration.

Mounting and Installation
The switch is designed as a 1U rack unit and can be mounted in standard 19-inch racks. The robust metal housing provides mechanical protection and good heat dissipation. The integrated fans (3 units) ensure efficient cooling, with heat dissipation specified at 1658.78 BTU/h. The LED indicators allow visual monitoring of operational status. A reset button is also included to restore the switch to factory settings if needed. Power supply is provided by an integrated power supply unit, connected to an AC outlet (100–240 V, 50/60 Hz). The maximum power consumption is 486.2 W.

Operational Advantages
The SG3428XMPP offers high scalability through the combination of PoE ports and SFP+ uplinks. Centralized management via cloud or CLI reduces maintenance effort, especially across multiple locations. Security features such as BPDU filtering, IP-MAC-port binding, and SSH/SSL support enhance network security. The support for ERPS (Ethernet Ring Protection Switching) enables rapid recovery from network failures in ring topologies. The operating temperature range of 0–40 °C and storage temperature range of -40–70 °C make the switch suitable for a wide range of operating conditions. The relative humidity during operation (10–90 %) and during storage (5–90 %) are also designed for robust use in various environments.

Scope of Delivery
The delivery includes the device itself, a network cable, a quick start guide, a rack mounting kit, and rubber feet. These components enable direct installation and commissioning without additional purchases.

Certifications
The switch complies with certifications CE, FCC, and RoHS, confirming conformity with European and American safety and environmental standards.
