Link Loss Carry Forward (LLCF) Switch
The 2131 media converter incorporates Link Loss Carry Forward (LLCF)
functionality as an aid in troubleshooting a remote connection.
A switch for enabling/disabling LLCF is located on the rear panel of the
converter. When LLCF is enabled, the FX ports as well as the TX ports on
the media converter do not transmit a link signal until they receive a link
signal from the opposite port. Refer to the page titled "Link Loss Carry
Forward" in the User Guide section of this manual for more detailed
information.
The unit is shipped with the LLCF disabled. To reset the LLCF, simply
slide the switch to the appropriate setting.

MDI-II to MDI-X Switch
All 2131 media converters with twisted-pair ports have an MDI-II to MDI-
X switch that eliminates the need for crossover cables. This switch is
located on the bottom of the unit directly below the RJ-45 connector and
allows simple setup in either straight through or crossover configurations.
