Grandstream GWN7062ET: Two FXS Telephone Ports Are Not LAN Ports

Grandstream GWN7062E and GWN7062ET; distinguish GWN7062ET telephone interfaces.

Applies to: Grandstream GWN7062E and GWN7062ET; distinguish GWN7062ET telephone interfaces.

Official evidence: Grandstream GWN7062E and GWN7062ET.

Before you begin

• Check exact GWN7062E vs GWN7062ET rear label and printed port icons.
• Unplug any mismatched cable before connecting network hardware.

What to check / do

1. Compare model variants: the ET adds two FXS analog telephone ports; these are not Ethernet switch ports.
2. Connect computer or network switch only to a documented Ethernet LAN interface.
3. If voice service is intended, follow the official model-specific FXS configuration and provider requirements; do not assume Internet service alone enables analog voice.
4. Verify Ethernet IP address and confirm voice line registration separately if applicable.

Verify the result

• Computer obtains an IP address on Ethernet port.
• No Ethernet cable is placed into the small analog phone port.

If the result is not what you expected

• Stop changing settings if you cannot identify the model or a reliable administrator recovery path.
• Use the exact manufacturer support link below and quote your hardware label, firmware version, and what changed.

Restore / undo

Return all cables to labeled correct sockets; do not reset the gateway to solve a physical connector mismatch.
