2 Test Your Internet Connection
After you have connected the hardware and turned on the ONU-631HA, open a web
browser on your computer and go to any web site (for example, www.zyxel.com) to test
your Internet connection.
Troubleshooting
1 The POWER light is not on when I connect power to the ONU-631HA.
• Check that the power source is turned on.
• You might be using the wrong power adaptor. Use the included power adaptor only.
• If you are using the correct power adaptor, disconnect and re-connect the power
adaptor to turn on the ONU-631HA again.
• If the POWER light is still not on, use a different power outlet.
• If the problem continues, contact your local vendor.
2 The PON light is off.
