with the copper link partner. The parameters used by the media
converter will be determined by the Copper Speed (Bank 2 -

settings. Pause receive and send will be disabled.
Link Pass-Through Mode (Switch 2) Switch Position Mode
Up (default) Link Pass-Through Mode
Down Standard Mode
Link Pass-Through Mode: 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 by the media converter.
If the installation has a media converter on both ends of the fiber
link and both are set-up for Link Pass-Through, then 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.
Standard Mode: In this mode, 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.
