4. Setup Instructions
The YuLinca 6-Port 2.5G Unmanaged Network Switch is designed for simple plug-and-play operation. No software installation or complex configuration is required.
- Power Connection: Connect the provided DC 12V/1A power adapter to the DC 12V input port on the switch and then plug it into a power outlet. The PWR indicator light will illuminate.
- Ethernet Device Connection:
- For devices requiring 2.5G, 1G, or 100M speeds, connect them to any of the 4x 2.5GBASE-T RJ45 ports (ports 1-4) using standard Ethernet cables (CAT5e or higher recommended for optimal performance).
- For devices requiring 1G, 2.5G, or 10G fiber optic connections, insert compatible SFP/SFP+ modules into the 2x 10G SFP+ ports (ports 5-6) and connect fiber optic cables.
- Verify Connection: Once devices are connected, observe the LED indicators on the switch.
- For RJ45 ports (1-4): A green light indicates a 2.5G link. A yellow light indicates a 10/100/1000M link.
- For SFP+ ports (5-6): An illuminated SFP indicator signifies a normal link connection.

5. Operating Instructions
Once powered on and connected, the YuLinca 6-Port 2.5G Unmanaged Network Switch operates automatically. It functions as a layer 2 Ethernet switch, forwarding data frames between connected devices based on MAC addresses.
- Automatic Negotiation: Each 2.5GBASE-T port automatically detects the speed (10/100/1000Mbps/2.5Gbps) and duplex mode of the connected device.
- LED Indicators: Monitor the LED indicators on the front panel to check the status of each port and the power.
- PWR LED: Green when the switch is powered on.
- RJ45 Port LEDs (1-4): Green for 2.5G link, Yellow for 10/100/1000M link. Blinking indicates data activity.
- SFP+ Port LEDs (5-6): On when a link is established. Blinking indicates data activity.
- Fanless Design: The switch operates silently due to its fanless design, making it suitable for noise-sensitive environments.

6. Maintenance
The YuLinca 6-Port 2.5G Unmanaged Network Switch requires minimal maintenance due to its robust design and fanless operation.
- Cleaning: Periodically clean the exterior of the switch with a soft, dry cloth. Do not use liquid or aerosol cleaners.
- Ventilation: Ensure that the cooling holes on the sides of the switch are not obstructed to maintain proper airflow and prevent overheating.
- Environment: Operate the switch within the specified temperature range (-10~50°C) and avoid excessively humid or dusty environments.
- Firmware: As an unmanaged switch, no firmware updates are typically required or available for user installation.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No Power (PWR LED off) | Power adapter not connected or faulty; power outlet not working. | Check power adapter connection. Try a different power outlet. Ensure the power adapter is the correct one (DC 12V/1A). |
| No Link Light on a Port | Ethernet cable faulty or disconnected; connected device is off or faulty; incorrect cable type. | Ensure the Ethernet cable is securely connected at both ends. Try a different cable. Verify the connected device is powered on and functioning. For 2.5G connections, use CAT5e or higher. |
| Slow Network Speed | Cable quality issues; connected device's network adapter limitation; network congestion. | Ensure you are using CAT5e or CAT6/6A cables for 2.5G speeds. Check the network adapter settings on your connected device. Reduce network traffic if possible. |
| SFP+ Port Link Issues | SFP/SFP+ module incompatible or faulty; fiber cable damaged or incorrect type. | Ensure the SFP/SFP+ module is compatible with the switch and correctly inserted. Check the fiber optic cable for damage and ensure it's the correct type for the module. |
