Smart Link Pass-Through: In this mode, the link state
on one connection is directly reflected through the
Media Converter Module to the other connection. If link
is lost on one of the connections, then the other link will
be brought down by the Media Converter Module.
With Media Converters on both ends of the fiber link
and both setup for Link Pass-Through, a loss of copper
link on the far end device will propagate through both
Converters and will result in a 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.
