Link Fault Signaling (LFS)
Connect the FX ports of two Media Converters, A and B, through the fiber
optic cable.
Link Fault of the FX port:
A Link Fault condition will be sensed on the TX port whenever the media
converter detects a Link Fault condition on the FX port. Thus, the 100,
LNK/ACT, and FDX/COL LEDs of the media converter would be off.
Link Fault of the TX port of Media Converter A:
Media Converter A
: A Link Fault condition will be sensed on the FX port
whenever the media converter detects a Link Fault condition on the TX
port. Thus, the 100, LNK/ACT, and FDX/COL LEDs of the TX port of the
Media Converter A would be off.
Media Converter B
: A Link Fault condition indication will be sent to the FX
port of the Media Converter B. Then, a Link Fault condition will be sensed
on the TX port of the Media Converter B whenever the Media Converter B
detects a Link Fault condition on the FX port. Thus, the 100, LNK/ACT,
and FDX/COL LEDs of the Media Converter B would be off.
