Smart Link Pass-Through Mode
Standard Mode: In this mode (if Fiber Negotiation is set to OFF),
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
link or copper link can take place without affecting the other
connection.
However, if the Fiber Negotiation (switch 1) is set to Auto, then a
loss of link on the copper side will result in a loss of link on the
fiber side.
Smart Link Pass-Through: In this mode, the link state on one
connection is directly reflected through the Media Converter to the
other connection. If link is lost on one of the connections, then the
other link will be brought down.
If the installation has a Media Converter on both ends of the fiber
link and both are setup for Smart Link Pass-Through, a loss of
copper link on the far end device will propagate through both
Media Converters and will result in a loss of link at the near end
device. This would resemble a direct copper connection.

Disabled
Disabled: The Media Converter Module will not monitor for fiber
fault.
Enabled: If the Media Converter Module detects a loss of fiber
signal on the fiber receiver, it will immediately disable its fiber
transmitter signal. This notifies the fiber link partner that an error
condition exists on the fiber connection.

Enabled and the local Media Converter is set up with Smart Link
