converter will be determined by the Duplex (switch 4) and Speed
(switch 5) DIP switch settings.
Link Mode (Switch 2)
Switch Position Mode
Up (default) Smart Link Pass-Through Mode
Down Standard Mode
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 by the media converter.
If the installation has a media converter on both ends of the fiber
link and both are set-up for Smart 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, 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 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
