Troubleshooting
General
•
Ensure power is supplied to the Media Converter – use
of the supplied power adapter is highly recommended.
•
Ensure that the Media Converter Module and MCR-MGT
Management Module are securely seated in the chassis
(See the section Removing Modules in this guide).
•
Ensure both devices on either end of the fiber are
compatible. If using a simplex fiber connection, ensure
that you have both an Upstream (U) and Downstream
(D) Media Converter.
•
Ensure all cabling is of the correct type and is in good
working order.
•
For duplex fiber connections, ensure the RX and TX has
been reversed between the two Media Converters.

the SMI Media Converter for loopback mode. Refer to
the Media converter guide that came with your SMI
Media Converter for DIP switch setup.
