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
cop
per port when FXLL is enabled.
For more information on LinkLoss, visit the B+B SmartWorx. If unsure of how to
use these features in a specific configuration, contact B+B SmartWorx.
AUTO NEGOTIATION
The IE-iMcV-2xLIM, TX/SFP module includes 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.
If the twisted pair port on the other device does not have the ability to Auto
Negotiate or if the 100 Mbps half-duplex connection is desired, then Auto
Negotiation must be disabled. Half-duplex and full-duplex settings must be set
manually to match the connected devices.
The following diagram shows a typical application with three possible
configurations.
