If you experience any problems with the module, check the
following items before contacting SMC Technical Support:
•
Ensure that the switch with the Gigabit Extender Module is
powered up.
•
Ensure that the device attached to the module is powered up
and operating correctly.
•
Ensure that the module is properly seated in the slot.
•
Verify that the attached device is configured to match the
communication mode used by the module (1 Gbps and full
duplex).
•
Check the connectors on both ends of the cable to be sure they
are properly engaged. When attaching fiber cable to an SC-type
port, be sure the plug clicks into place to ensure that it is
properly seated.
•
If you are using fiber optic cable with an ST-type connector (in
conjunction with the SC-ST Converter*), try switching the TX
and RX connectors.
•
Be sure the fiber terminators are clean. You can clean the cable
plugs by wiping them gently with a clean tissue or cotton ball
moistened with a little ethanol. Dirty fiber terminators on fiber
optic cables will impair the quality of the light transmitted
through the cable.
* You may use an SC-ST Converter (SMC Part Number:
99-012034-091) to attach fiber cable with an ST-type
connector to the SC-type port on the Gigabit Extender Module.
