With the Link Fault Pass Through function enabled (optional with 
switch LFP), TP port and FX port of the same converter will inform 
each other the fault link status so that when one side of the link fails, 
the other side will force the link to shut down as soon as noticed. The 
procedure will be illustrated as shown below. 
 
If link fail happens on TP port (A), the FX port (A) sends non-idle 
pattern to notice the FX port (B). The FX port (B) then forces its TP 
port (B) to link failed after receiving the non-idle pattern. Link status 
LED will also be off for both Converters and Devices as shown below.
