Link Fault Pass-Through (LFPT)

Link Fault Pass-Through (LFPT) is a troubleshooting feature that combines TX and
FX LinkLoss from both the local and remote IE-iMcV-2xLIM, TX/SFP modules.
LFPT is enabled by turning on both FX and TX LinkLoss on both modules. This
feature allows either end of the conversion to detect a link fault occurring at the
other end of the media conversion chain.


Regardless if there is a break in segment 1, 2 or 3, the link will drop on the
switches at both ends. The link fault is passed through the media conversion and
is observed at each end. It acts just like it would if the devices were directly
connected.

Far End Fault (FEF)

By default, FEF is disabled. When enabled, and a fault occurs on the fiber line,
affecting data in one direction, an FEF signal will be sent in the opposite direction,
indicating the fault. When enabling LFPT, FXLL will act on this signal propagating
the loss of link to the copper port when FXLL is enabled.

Auto Negotiation on IE-iMcV-2xLIM, TX/SFP

IE-iMcV-2xLIM, TX/SFP modules include the feature Auto Negotiation. When
Auto Negotiation is enabled, the module negotiates as a 100 Mbps full-duplex
device. If the connected device can operate at 100 Mbps full-duplex and support
Auto Negotiation, a link is established. Auto Negotiation (DIP Switch #1) is
enabled by default.
