LFPT
The Miniature Media Converter with LFPT includes a DIP Switch,
located on the back of the unit. DIP Switch functions are as follows:
Switch Up
LFPT ON
Switch
Down
LFPT OFF
Link Fault Pass-Through (LFPT) is a troubleshooting feature that
combines TX and FX LinkLoss from both the local and remote MiniMc,
TX-FX/SFP modules. LFPT is enabled by turning on the DSW 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.
