MEDIA CONVERTER WITH TEST MANAGER, FAULT DETECTION METHOD, AND SYSTEM USING THE CONVERTER AND METHOD

摘要

PROBLEM TO BE SOLVED: To provide a fault detection system and method which makes it easy to detect faults in the link with a media converter and can identify the location of the fault. SOLUTION: When a link includes plural media converters which connect a 100BASE-TX: UTP cable and a 100BASE-FX: optical cable and a test manager detects link disconnection, a test mode is activated and a trigger packet is sent to the plural media converter from a media converter with the test manager. It is judged whether or not a response packet from each media converter is received within a certain period of time and a fault location is identified based on the response packet.
