The Fiber Driver series are highly reliable units. If there are any operating
problems, the fault probably lies in some other aspect of the configuration.
However, if after following the troubleshooting steps below (in order), you
find that the unit is still not functioning correctly, please contact your local
representative.
Review all link LEDs to ensure that those ports you believe should be
functioning are properly attached to a cable.
Verify the correct fiber optic cables are being used, i.e. multi-mode or single

functioning are properly configured.
If the suspect ports are not configured properly, re-configure the port
through SNMP management or the Administrative Interface.
Ensure that the equipment attached to this module is configured properly.
