Product Features
Technical Overview
This L2+ managed switch supports comprehensive networking standards including IEEE 802.1Q for VLAN tagging, IEEE 802.1p for traffic prioritization, and IEEE 802.1x for port-based authentication. The 10/100/1000Base-T copper ports auto-negotiate speed and duplex, while the 1000Base-X SFP slots accept optical or copper transceivers for uplink flexibility.
Zero-Touch Provisioning simplifies deployment by allowing pre-configured switches to automatically adopt settings from a central controller. The switch consumes 20.60 watts under typical load, contributing to energy-efficient network operations.
Relevant factors for this section include Features, Total Number of Network Ports, Network (RJ-45), Modular. When those points are considered together, they give buyers a clearer picture of how the product is equipped, how it fits into deployment, and what kind of day-to-day role it is meant to support.
A strong technical summary explains how the product's interfaces, hardware profile, and operating characteristics work together in real deployment. Buyers often need this context to confirm compatibility with existing devices, expected performance in daily use, and whether installation will be straightforward for IT staff or end users.
Key Product Advantages

- Rack-mountable with included kit
- Desktop-ready with rubber feet
- Dual voltage input
Advanced Network Control
Manage VLANs, QoS, port security, and monitoring through the intuitive web interface or Omada SDN controller for centralized management of multiple switches.
- VLAN segmentation
- Traffic prioritization
- Port security features
Deployment / Use Cases
The SG3428 serves as an ideal access or distribution layer switch for small to medium business networks, educational facilities, and retail environments. Its 24 copper ports connect workstations, IP phones, wireless access points, and surveillance cameras, while the SFP slots provide high-speed uplinks to core switches or servers.
In office settings, the switch enables organized cable management through rack mounting while supporting VoIP deployments with QoS prioritization. For retail or hospitality applications, it provides reliable connectivity for point-of-sale systems, digital signage, and guest networks with appropriate security segmentation.
Small Business Core Switching
Deploy as the main switch for offices with 20-30 devices, using SFP uplinks for connecting to servers or internet gateways.
Classroom or Lab Environment
Provide dedicated connectivity for computer labs or multimedia classrooms with silent fanless operation and easy management.
Physical Profile
The SG3428 features a durable metal construction measuring 1.70" (43.18 mm) in height, 17.30" (439.42 mm) in width, and 7.10" (180.34 mm) in depth. This 1U rack-mountable design optimizes space in network cabinets while maintaining sufficient port density for most small to medium deployments. The compact footprint also allows for desktop placement where rack space is unavailable.
The physical profile is practical for deployment planning because the dimensions and weight are clearly defined: 1.70" (43.18 mm), 17.30" (439.42 mm), 7.10" (180.34 mm). This helps confirm rack, shelf, desk, or cabinet fit before installation.

User Manual
FAQ
How many devices can I connect to this switch?
The SG3428 provides 24 Gigabit Ethernet ports for connecting computers, printers, IP phones, wireless access points, and other network devices. Additionally, the 4 SFP slots can be used for uplinks to other switches or network infrastructure, effectively supporting networks with dozens of connected devices when properly configured.
What are the SFP slots used for?
The 4 SFP (Small Form-factor Pluggable) slots accept optical or copper transceivers to create fiber uplinks for longer distance connections between switches, or to connect to fiber-based network infrastructure. These slots provide flexibility beyond standard copper Ethernet, supporting distances up to kilometers with appropriate fiber transceivers.
Is this switch manageable?
Yes, the SG3428 is a fully managed Layer 2+ switch. It supports web-based management for configuring VLANs, Quality of Service (QoS), port security, link aggregation, and monitoring. The switch also supports Zero-Touch Provisioning for automated configuration when used with TP-LINK's Omada SDN controller.
Can this switch be rack-mounted?
Yes, the switch includes a rackmount kit for installation in standard 19-inch network racks. Its 1U height (1.70 inches) makes efficient use of rack space. For environments without rack infrastructure, rubber feet are included for stable desktop placement.
Does this switch support Power over Ethernet (PoE)?
No, the SG3428 does not provide Power over Ethernet. It is a non-PoE switch designed for data connectivity only. If you need to power devices like wireless access points or IP phones through the network cable, you would need to consider a PoE-enabled switch model instead.
What networking standards does this switch support?
The switch complies with multiple IEEE standards including 802.3ab for Gigabit Ethernet over copper, 802.1Q for VLAN tagging, 802.1p for traffic prioritization, 802.1x for port-based authentication, and 802.3x for flow control. These standards ensure interoperability with other network equipment and support advanced network features.
