4. Setup
4.1 Rack Mounting
The TL-SG3428MP comes with a rackmount kit for installation in a standard 19-inch equipment rack. Attach the rackmount brackets to the sides of the switch using the provided screws. Secure the switch into the rack using appropriate rack screws.
4.2 Desktop Placement
For desktop use, attach the included rubber feet to the bottom of the switch to prevent scratching and ensure stability. Place the switch on a flat, stable surface with adequate ventilation around the unit.
4.3 Power Connection
Connect the provided AC power cord to the power inlet on the rear panel of the switch and then to a suitable power outlet. Ensure the power source meets the voltage requirements (100-240V AC, 50/60Hz).
4.4 Network Connection
Connect network devices (e.g., computers, servers, IP cameras, IP phones, access points) to the RJ45 ports (1-24) using Ethernet cables. For high-speed uplinks or connections to other network segments, insert compatible SFP modules into the SFP slots (25-28) and connect fiber optic cables.
4.5 Initial Configuration
The switch can be managed via the Omada SDN platform or in standalone mode. For Omada SDN, ensure your Omada controller (hardware or software) is running and discoverable. For standalone management, access the switch's web-based GUI or CLI (Command Line Interface) via the console ports. Refer to the Quick Installation Guide for initial IP address and login credentials.
5. Operating the Switch
5.1 Power over Ethernet (PoE) Functionality

The TL-SG3428MP provides 24 PoE+ ports, each capable of delivering up to 30W of power, with a total power budget of 384W. This allows for powering PoE-compatible devices such as IP cameras, VoIP phones, and wireless access points directly through the Ethernet cable, simplifying deployment and reducing cabling. The switch also features PoE Auto Recovery, which automatically reboots unresponsive PoE-powered devices.
5.2 Omada SDN Integration

The Omada Software Defined Networking (SDN) platform enables centralized management of your network. You can manage the TL-SG3428MP using an Omada Hardware Controller, Omada Software Controller, or through the Omada cloud-based controller for remote access. This integration simplifies configuration, monitoring, and troubleshooting across multiple sites from a single interface. Ensure your devices and controllers are equipped with SDN firmware for compatibility.
5.3 Advanced Features
The switch offers a suite of advanced L2+ features for enhanced network security and performance:
- 802.1Q VLAN: For network segmentation and traffic isolation.
- IP-MAC-Port Binding: Binds IP addresses, MAC addresses, and port numbers to prevent unauthorized access.
- Access Control List (ACL): Filters network traffic based on various criteria.
- Port Security: Limits the number of MAC addresses learned on a port to prevent MAC flooding attacks.
- DoS Defend: Protects against Denial of Service attacks.
- Storm Control: Prevents excessive broadcast, multicast, or unknown unicast traffic from degrading network performance.
- DHCP Snooping: Enhances network security by filtering untrusted DHCP messages.
- 802.1X Radius Authentication: Provides port-based network access control.
- IPv6 Support: Ensures compatibility with next-generation internet protocols.
- Static Routing: Allows for basic inter-VLAN routing without a dedicated router.
6. Maintenance
6.1 Firmware Updates
Regularly check the TP-Link official website for the latest firmware versions. Updating the firmware can provide new features, performance improvements, and security patches. Follow the instructions provided with the firmware update package carefully.
6.2 Configuration Backup and Restore
It is recommended to regularly back up your switch's configuration. This allows you to quickly restore settings in case of accidental changes or system issues. The web GUI or CLI typically provides options for backing up and restoring configuration files.
6.3 Environmental Considerations
Ensure the switch operates within its specified temperature range (0–45 °C) and humidity levels. Maintain proper airflow around the device to prevent overheating. Avoid placing the switch in direct sunlight or near heat sources.
7. Troubleshooting
If you encounter issues with your TL-SG3428MP switch, consider the following general troubleshooting steps:
- No Power: Verify the power cord is securely connected to both the switch and the power outlet. Check the power source.
- No Link/Connectivity: Ensure Ethernet cables are properly connected to both the switch port and the connected device. Check the link/activity LEDs on the switch. Try a different cable or port.
- PoE Device Not Powering On: Confirm the connected device is PoE compatible. Check the PoE status LED for the port. Ensure the total PoE budget is not exceeded.
- Cannot Access Management Interface: Verify your computer's IP address is in the same subnet as the switch's management IP. Check physical connectivity. If using Omada SDN, ensure the controller is operational and the switch is adopted.
- Network Performance Issues: Check for excessive network traffic or loops. Review switch logs for error messages.
