Perle Systems S-100-XXXXX manual Unused Switch

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
