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.
