Both ports in the channel can
establish a link to a networking device,
but one of the ports is connected to
another media converter that also
supports the Smart MissingLink
feature, forming a chain of converters.
A link has been lost on one of the
ports in the chain, causing a ripple
affect through the chain of converters.
Alternatively, one of the ports is only
able to form an intermittent link with its
networking device.
For troubleshooting suggestions, refer
to Problem 8 in Chapter 3,
