The TP-Link TL-SG3428XF is a fully managed L2+ Switch from the Omada series, designed for use in enterprise networks, campus infrastructures, and ISP environments. It offers a comprehensive range of management and security functions, as well as high network performance tailored to the requirements of modern networks. The switch features 24 fiber ports, including 20 Gigabit-SFP-Ports and 4 Gigabit-SFP/RJ45-Combo-Ports, supplemented by 4 10G-SFP+-Ports for uplink. This configuration enables a flexible and scalable network architecture suitable for connecting with other switches and integrating end devices.

Applications

The TL-SG3428XF is designed for use in medium to large networks where central management, high bandwidth, and advanced security functions are required. It is particularly well-suited for environments requiring stable and secure data transmission over fiber optic cables, such as office buildings, schools, hotels, or retail stores. Integration with the Omada SDN system enables centralized control via the cloud, allowing network management regardless of location.

Functions and Features in Detail

The switch supports static routing with up to 48 IPv4 and 48 IPv6 routes, enabling efficient forwarding of internal traffic. Quality of Service (QoS) functions at L2/L3/L4 level ensure prioritized data transmission, especially for voice and video applications. This includes IGMP-Snooping and MLD-Snooping, which optimize multicast traffic. VLAN support includes port-based VLAN, private VLAN, tagged VLAN, VLAN mapping, and voice VLAN, with up to 4000 VLANs configurable. Access Control Lists (ACLs) allow fine-grained control of network access based on MAC addresses, IP addresses, ports, and VLAN IDs.

Technology Explained Simply

The switching capacity is 128 Gbit/s, ensuring non-blocking data processing. The transfer rate is 95.23 Mpps, and the MAC address table contains 16,000 entries, enabling efficient device detection and addressing. The switch supports Jumbo Frames up to 9000 bytes, increasing efficiency when transmitting large data packets. The Store-and-Forward technology ensures error-free data transmission by receiving and verifying the entire message before forwarding. The data packet buffer memory of 12 MB supports data traffic processing under high loads.

Compatibility and Accessories

The TL-SG3428XF is compatible with SFP and SFP+ modules available for various fiber optic cable types (single-mode, multi-mode) and distances. Compatible modules include, for example, the MiniGBIC Module 10GBit SFP+ LC Single-Mode LX TL-SM5110-LR, the MiniGBIC Module 1 GBit SFP LC Singlemode LX TL-SM311LS, or the SFP+ Direct Attach Cable 3 m SM5220-3M. These modules allow flexible adaptation to specific network requirements. The Omada SDN platform supports centralized management via the cloud, with features such as Zero-Touch Provisioning (ZTP) and intelligent monitoring simplifying network administration.

Mounting and Installation

The switch is designed as a 1U rack device and can be installed in standard 19-inch racks. It features a console port with RJ-45/Micro-USB connection for local configuration via CLI (Command Line Interface). The power supply is provided by an integrated AC power unit, with support for redundant power supply using two power supply units to increase availability. The operating temperature ranges from 0 to 45 °C, and the storage temperature can range from -40 to 70 °C. The relative humidity during operation is 10–90 %, and during storage, 5–90 %.

Operational Advantages

The TL-SG3428XF offers high network security through features such as IP-MAC-Port binding, BPDU filtering, loop protection, DHCP Snooping, and DoS defense. Authentication options include 802.1X, AAA, RADIUS, and TACACS+, enabling secure access control. Web-based management, along with support for SNMPv1/v2c/v3, SNTP, and Dual Image, provides various options for configuration and maintenance. System event logging and MIB support according to RFC standard facilitate network monitoring and diagnostics. LED indicators support visual status monitoring of the device.

Scope of Delivery

The scope of delivery includes the TL-SG3428XF switch, a power cable, a quick installation guide, a rack mount kit, and rubber feet. These components enable quick and easy installation in the rack.
