4. Installation
4.1 Desktop Placement
Place the switch on a flat, stable surface. Ensure adequate ventilation around the device to prevent overheating.
4.2 Wall-Mounting
The TL-SG116 can be mounted on a wall using the integrated mounting slots on the underside of the device. Use appropriate screws (not included) for your wall type, ensuring they are securely fastened before mounting the switch.
5. Connecting the Switch
The TL-SG116 is a plug-and-play device, requiring no software configuration. Follow these steps to connect your switch:
- Connect Power: Plug the provided power adapter into the switch's power port and then into a standard electrical outlet. The Power LED on the switch should illuminate.
- Connect Network Devices: Use Ethernet cables to connect your network devices (e.g., computers, printers, gaming consoles, routers, other switches, smart TVs) to any of the 16 Gigabit Ethernet ports on the switch.
- Verify Connection: Once a device is connected, the corresponding Link/Act LED on the switch will light up, indicating an active connection. It will blink to show data activity.

6. Operation
The TL-SG116 operates as an unmanaged switch, meaning it automatically handles network traffic without requiring user configuration. Key operational features include:
- Auto-Negotiation: Each port automatically detects the link speed of the connected network device (10/100/1000Mbps) and intelligently adjusts for compatibility and optimal performance.
- Auto MDI/MDIX: Eliminates the need for crossover cables, simplifying network setup.
- IEEE 802.3X Flow Control: Provides reliable data transfer by preventing packet loss during periods of high network traffic.
- Port-based 802.1p/DSCP QoS: Prioritizes traffic to ensure high quality for video or voice data transmission, reducing lag.
- IGMP Snooping: Optimizes multicast applications, such as IPTV, by efficiently managing multicast traffic.
- Energy-Efficient Technology: The switch incorporates innovative technology to reduce power consumption, contributing to energy savings.

7. Maintenance
The TL-SG116 is a fanless device, ensuring quiet operation and minimizing maintenance requirements. To ensure optimal performance and longevity:
- Keep the switch in a well-ventilated area, free from dust and direct sunlight.
- Periodically clean the exterior of the switch with a soft, dry cloth.
- Avoid blocking the ventilation holes.
8. Troubleshooting
If you encounter issues with your TL-SG116 switch, refer to the following common troubleshooting steps:
- No Power LED:
- Ensure the power adapter is securely connected to the switch and a working electrical outlet.
- Verify the power outlet is functional by plugging in another device.
- No Link/Act LED for a connected device:
- Check that the Ethernet cable is securely plugged into both the switch port and the network device.
- Ensure the connected device is powered on and its network adapter is enabled.
- Try a different Ethernet cable.
- Try connecting the device to a different port on the switch.
- Verify the network device itself is functioning correctly.
- Slow Network Speed:
- Ensure all connected devices and cables support Gigabit Ethernet (Cat5e or higher cables are recommended for Gigabit speeds).
- Check for excessive network traffic or bandwidth-intensive applications running on your network.
- Verify that your internet service provider (ISP) is delivering the expected speeds to your router.
