Troubleshooting

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.
