Troubleshooting Troubleshooting If you have any problems with the adapter, first refer to the following troubleshooting guide. If you cannot solve the problem, call 1-800-BE-SHARP. Problem Solution The POWER indicator is off even though the adapter is plugged into an outlet. • Make sure that the adapter is plugged into a standard (120 V, 60 Hz) outlet. • Make sure the outlet has power. Try plugging the adapter into a different outlet. • If the temperature of the adapter rises to the point that operation will be impaired, the adapter will automatically stop operating. Unplug the adapter and let it cool. Once the adapter has cooled, try using it again. Communication is not possible on the network • Is the PLC indicator on or blinking? If not, try plugging the adapters into outlets that are as close to each other as possible. If the PLC indicator still does not light, it is possible that the registration of an adapter has been canceled. Re-register the adapter as explained on page 11. If the PLC indicator lights in some outlets but not in others, it is likely that some condition of your power lines prevents communication in some outlets. Use the adapters in outlets where communication is possible. • If the PLC indicator lights normally but the LAN port indicators do not light, make sure the LAN cables are firmly inserted in their ports. Make sure that the LAN cables are category 5 or 6 cables that support 100BASE-TX. 13
