Fast Ethernet Media Converter – Installation Guide
6
If the media converter has been set to Link Pass-Through mode, the
effect will be the same as FEF, since the link loss on the fiber receiver
will bring down the copper link, which will in turn cause the transmit
fiber link to be brought down.
Note: This switch needs to be set to either generate or detect the
FEF signal.
Disabled: The media converter will not monitor for or generate Far
End Fault.
The following diagram is an illustration of the operation of this feature.
(A) – Remote Media Converter setup for Far End Fault Enabled, Auto
Negotiation – OFF and Link Mode – Standard.
(B) – Local Media Converter setup for Link Pass-Through and Auto
Negotiation - OFF
