*Refer to the following table for troubleshooting.
*Refer to the
Remote Fiber Diagnosis
section for instructions.
If an ICF-1280I converter is deployed at the beginning or at the end of the
topology in Linear mode or Star mode, the unused port should be
disabled. In such cases, it is recommended to use an ICF-1180I series
converter. Please use the ICF-1180I series with Rev. 1.3, or higher
versions, to connect with the ICF-1280I series.
