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
The POWER indicator is
off even though the
adapter is plugged into an
outlet.
Communication is not
possible on the network
• 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.
• 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.
