ONU-6100B-2x Series User's Guide Troubleshooting 1 The POWER light is not on when I connect power to the ONU-6100B-2x. • 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 ONU6100B-2x 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. • Check the connector on the optical cable and the PON port. Make sure they are clean and dust-free. Use an air duster to clean the connectors. Do NOT use a wet cloth to clean the connectors. • Check the optical cable. Make sure it is not broken. If the cable is broken, contact your service provider to have the cable/connector replaced. Do NOT attempt to replace the optical cable/connector yourself. 3 I cannot connect to the Internet. • Check the port connections and the lights. • There might be problems with the optical network setting.
