10/100BASE-TX to 100BASE-FX Media Converter
5. Link-Fault-Passthrough
Connect the FX ports of Media Converters A and B through the fiber cable.
1. Link Fault on the FX port of Media Converter A: A Link Fault condition will be
sensed on the TX port whenever Media Converter A detects a Link Fault condi-
tion on the FX port. Thus, the 100, LNK/ACT, and FDX/COL LEDs of the TX port
of Media Converter A would be off.
2. Link Fault on the TX port of Media Converter A: A Link Fault condition will be
sensed on the FX port whenever the media converter detects a Link Fault condi-
tion on the TX port. Thus, the 100, LNK/ACT, and FDX/COL LEDs of the TX port
of Media Converter A would be off.
The Media Converter B: A Link Fault condition will be sent to the FX port of
Media Converter B. Then a Link Fault condition will be sensed on the TX port of
Media Converter B whenever Media Converter B detects a Link Fault condition on
the FX port. Thus, the 100, LNK/ACT, and FDX/COL LEDs of Media Converter B
would be off.
