Appendix B: Questions and Answers
Section 1: Troubleshooting Modem LED Problems
Troubleshooting the modem portion of this Cable Modem begins with observing the
front panel lights (also called LEDs - light emitting diodes). The pattern of these lights
indicates the status of the modem. Interpreting the pattern correctly can indicate
whether the modem is functioning properly or not. If there is a problem, the lights
provide clues as to what the problem might be. The Cable Modem does not require any
routine maintenance. If you cannot identify and correct a fault using these
troubleshooting procedures, please contact your cable television (CATV) Internet
Service Provider (ISP).
Question 1: The Power Light Is Off
Answer:
The normal state for this light is solid red. If the Power light is off, then the modem
is not receiving power. Possible Solutions:
1. Check to make sure the power cable is firmly plugged into both the cable modem
and the electrical outlet. Try unplugging, then reconnecting the cable at each end.
2. Check that the wall outlet is working. Test it by using a light or some other device in
the suspect outlet.
3. If the power light remains off, the external power supply or the power cord is
probably defective. Contact the supplier of the Cable Modem for assistance.
Question 2: The Cable Light Is Off
Answer:
The normal state for this light is solid green. If the Cable Light Is Off, then the
modem is not detecting the downstream radio frequency (RF) signal provided by the
cable network. This could be caused by any of the following:
• Radio frequency noise in the home
• Damaged cable
• Bad or loose cable connections
• Unterminated connections
• Problem with the cable on the street
• Problem in the cable network
Possible Solutions:
1. Disconnect and then reconnect the power. This will automatically reset the
modem.
2. Wait at least 4 minutes.
3. If the Cable light is still off, then there could be a problem with the cable wiring.
Check all cables between the modem and the ground terminal outside the house.
Unplug the power again, then plug it back in as before.
4. If the Cable light is still off, there might be a problem with the cable network or the
modem. Contact your cable provider.
