Setup Instructions
Follow these steps to set up your UGREEN Network Switch:
- Connect the Power Adapter: Insert the DC power adapter into the power port on the switch and then plug the adapter into a standard electrical outlet. The power LED indicator on the switch should illuminate.
- Connect to Your Router/Modem: Take an Ethernet cable (not included) and connect one end to an available LAN port on your router or modem. Connect the other end of this cable to any of the 5 RJ45 ports on the UGREEN Network Switch.
- Connect Your Devices: Use additional Ethernet cables to connect your devices (e.g., computers, laptops, gaming consoles, smart TVs, network printers, security cameras) to the remaining RJ45 ports on the UGREEN Network Switch.
- Verify Connection: Once devices are connected, the corresponding LED indicators on the switch for each active port should light up, indicating a successful connection. Your devices should now have wired internet access.

Operating Instructions
The UGREEN Network Switch operates automatically once connected. It is a plug-and-play device that requires no software installation or configuration.
- Automatic Negotiation: The switch automatically detects the network speed (10/100/1000Mbps) and duplex mode (half/full) of connected devices.
- LED Indicators: Each RJ45 port has an associated LED indicator. A solid green light typically indicates a stable link, and a blinking light indicates data activity.
- Power On/Off: To power off the device, simply unplug the DC power adapter from the electrical outlet.

Maintenance
To ensure the longevity and optimal performance of your UGREEN Network Switch, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to clean the exterior of the switch. Do not use liquid cleaners or aerosols.
- Ventilation: Ensure the switch is placed in a well-ventilated area to prevent overheating. Do not block any ventilation openings.
- Environment: Avoid exposing the switch to extreme temperatures, humidity, or direct sunlight.
- Cable Management: Keep Ethernet cables neatly organized to prevent strain on the ports and accidental disconnections.
Troubleshooting
If you encounter issues with your UGREEN Network Switch, refer to the following common problems and solutions:
- No Power:
- Ensure the power adapter is securely connected to both the switch and a working electrical outlet.
- Verify that the power outlet is functional by plugging in another device.
- No Network Connection on a Device:
- Check the Ethernet cable connecting the device to the switch. Ensure it is securely plugged into both ends.
- Verify the LED indicator for that specific port on the switch. If it's off, try a different port or cable.
- Ensure the main Ethernet cable from your router/modem to the switch is properly connected and functioning.
- Restart the connected device, the switch, and your router/modem.
- Slow Network Speed:
- Ensure you are using Cat5e or Cat6 Ethernet cables for Gigabit speeds. Older Cat5 cables may limit speed.
- Check the network settings on your connected device to ensure it is configured for Gigabit Ethernet.
- Test the speed directly from your router/modem to isolate if the issue is with the switch or the internet service provider.
