7. Troubleshooting

This section provides basic troubleshooting steps for common issues.

7.1 No Power

• Verify that the power cable is securely connected to both the appliance and a working power outlet.
• Check the power outlet with another device to ensure it is functional.
• Ensure the power adapter is the correct one supplied with the device.

7.2 No Network Connectivity

• Check the Ethernet cable connections to the WAN and LAN ports. Ensure the link/activity LEDs are illuminated.
• Verify IP address configurations on the appliance and connected devices.
• Confirm that your internet service provider's modem is operational.
• Restart the SonicWall appliance and connected network devices.

7.3 Cannot Access Web Management Interface

• Ensure your computer is connected to a LAN port of the TZ500.
• Verify that your computer's IP address is in the same subnet as the TZ500's LAN interface (e.g., if TZ500 is 192.168.168.168, your computer should be 192.168.168.x).
• Try clearing your browser's cache or using a different browser.
• If the default IP address has been changed, use the new IP address.
