7. Troubleshooting
This section addresses common issues you might encounter with your YuLinca 6-Port 10G Web Managed Switch.
7.1 No Power
- Ensure the power adapter is securely connected to the switch's DC input port and a functional power outlet.
- Verify the power outlet is active by plugging in another device.
- Check the PWR LED on the switch; if it's off, there's no power.
7.2 No Link or Activity on a Port
- Confirm that the Ethernet cable is properly connected to both the switch port and the connected device.
- Check the Link/Act LED for the specific port. If it's off, there's no link.
- Ensure the connected device (e.g., computer, NAS) is powered on and its network adapter is enabled.
- Try using a different Ethernet cable to rule out a faulty cable.
- Test the port with another known working device.
7.3 Slow Network Speed
- Verify that you are using the correct Ethernet cable type for the desired speed (e.g., CAT6 or CAT6A for 10G connections).
- Ensure that both the switch port and the connected device's network adapter are configured for the expected speed (e.g., 2.5G or 10G). Check the Link/Act LED color for speed indication.
- Check for network congestion or high CPU usage on connected devices.
- Access the web management interface to review port statistics and diagnostics for potential issues.
7.4 Cannot Access Web Interface
- Ensure your computer's IP address is configured to be in the same subnet as the switch's default IP (192.168.2.1). For example, set your computer's IP to 192.168.2.10 with a subnet mask of 255.255.255.0.
- Confirm you are entering the correct default IP address (192.168.2.1) in your web browser.
- Try clearing your browser's cache or using a different web browser.
- Temporarily disable any firewall software on your computer that might be blocking access.
- If the switch's IP address was changed and forgotten, or if the default credentials do not work, perform a factory reset (refer to Section 6.1).
7.5 Configuration Changes Not Saved
- Always click the "Save Configuration" or equivalent button within the web management interface after making any changes. Changes are typically stored in volatile memory until explicitly saved to non-volatile memory.
