Setup
The TL-SX105 is designed for plug-and-play operation, requiring no software installation or configuration.
Step-by-Step Installation
- Connect to Power: Plug the provided power adapter into the switch's power port and then into a power outlet. The Power LED on the switch should illuminate.
- Connect Devices: Connect your network devices (e.g., computers, NAS, WiFi 6 APs, servers) to any of the RJ45 ports on the switch using Ethernet cables. The switch supports various speeds (100Mb/1G/2.5G/5G/10G) and will auto-negotiate the optimal speed for each connected device.
- Verify Connection: Observe the LED indicators next to each port. A solid green or yellow light indicates a successful link, and blinking indicates activity. The color of the LED may indicate the link speed (refer to specifications for details).

Operating Instructions
Once connected, the TL-SX105 operates automatically. It functions as an unmanaged switch, meaning it requires no user configuration for basic network extension.
Speed Auto-Negotiation
Each port on the TL-SX105 automatically detects the speed of the connected device and adjusts its operating speed accordingly. This ensures compatibility and optimal performance across devices with varying Ethernet standards (100Mbps, 1Gbps, 2.5Gbps, 5Gbps, 10Gbps).
LED Indicators
- Power LED: Indicates the power status of the switch.
- Link/Act LEDs (per port): Indicate the link status and network activity for each port. Refer to the product's detailed specifications or quick start guide for specific color/blink patterns indicating different speeds (e.g., 10G, 5G, 2.5G, 1G, 100M).

Performance and Connectivity
The TL-SX105 is designed to enhance network performance, especially for bandwidth-intensive applications.
- High-Speed Data Transfer: Facilitates rapid data transfer between connected devices, significantly reducing transfer times for large files to NAS devices or between high-performance workstations.
- Optimized for Modern Networks: Ideal for integrating 2.5G/5G/10G WiFi 6 Access Points, 10G NAS, 10G PCIe Adapters/NICs, 10G Servers, and gaming computers.
- Flow Control: IEEE 802.3X flow control ensures reliable data transfer by preventing packet loss during periods of high network traffic.

Figure 5: The TL-SX105 enables high-speed connections for devices like 10G NAS, servers, workstations, gaming computers, 8K video, and WiFi 6 APs.

Figure 6: Illustrates how the TL-SX105 can significantly reduce data transfer times compared to a standard Gigabit switch.
Maintenance
The TL-SX105 is designed for minimal maintenance. Follow these guidelines to ensure its longevity and optimal performance:
- Cleaning: Use a soft, dry cloth to clean the exterior of the switch. Avoid liquid cleaners or aerosols.
- Ventilation: Ensure the ventilation holes on the sides of the switch are not obstructed to allow for proper heat dissipation.
- Cable Management: Keep network cables organized to prevent strain on ports and improve airflow.
- Power Cycle: If the switch is unresponsive, disconnect the power adapter, wait for a few seconds, and then reconnect it.
Troubleshooting
If you encounter issues with your TL-SX105 switch, try the following basic troubleshooting steps:
- No Power: Ensure the power adapter is securely connected to both the switch and a working power outlet. Check if the power outlet is functional.
- No Link/Activity: Verify that Ethernet cables are securely connected to both the switch and the network device. Ensure the connected device is powered on and functioning correctly. Try using a different Ethernet cable.
- Slow Speed: Confirm that your connected devices and Ethernet cables (Cat5e or higher for multi-gig speeds) support the desired speeds. Ensure there are no bottlenecks elsewhere in your network (e.g., router, internet service provider).
- Intermittent Connection: Check for loose cable connections. Ensure the switch is placed in a well-ventilated area to prevent overheating.
