If the media converter has been set to Smart Link Pass-Through
mode, the effect will be the same as FFA, since the link loss on
the fiber receiver will result in bringing down the copper link, which
will in turn cause the transmit fiber link to be brought down.
Note: This feature only takes effect if Fiber Negotiation has been
turned off.
Disabled: The media converter will not monitor for or generate
Fiber Fault Alert.
The following diagram is an illustration of the operation of this
feature.

Fiber Negotiation – OFF and Link Mode – Standard.
(B) – Local Media Converter setup for Fiber Fault Alert Enabled,
Smart Link Pass-Through On and Fiber Negotiation - OFF

Pass-Through is configured.
5 – (A) Link on copper connection is not affected because Smart
Link Mode is set to Standard.
