loss of copper link at the near end device. This would, in effect, resemble a direct copper connection.

Standard Mode: In this mode, the links on the fiber and copper sides can be brought up and down independently of each other. A loss of link on either the fiber or copper port can occur without affecting the other connection.

Fiber Fault Alert (Switch 3)

Switch Position	Mode
Up (default)	Enabled
Down	Disabled

Enabled: If the Media Converter Module detects a loss of signal on the fiber receiver, it will immediately disable its fiber transmitter signal. This, in effect, notifies the fiber link partner that an error condition exists on the fiber connection.

If the remote Media Converter is set up for Fiber Fault Alert (FFA) and the local Media Converter is set up with Link Pass-Through, a loss of fiber link on either the transmit or receive line will be passed through to the local copper connection thus notifying the connected device.

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 Module will not monitor for or generate Fiber Fault Alert.
