Link Fault Signaling (LFS)

The LFS LED will immediately light to indicate when a cable has

been severed or when some other cause of disruption in service

has occurred. To fully appreciate the benefits of LFS, Four converters

can be used to build a primary and a secondary link. They must be

connected to a switch that supports Spanning Tree or Fast Spanning

Tree protocals. By default, transmission of data will travel via the

primary link. Once a fault has been detected by the converter,

transmission will automatically be switched to the secondary link,

resulting in ‘non-stop’ network connectivity.

Note: The LFS feature influences both fiber and copper segments.

Therefore, when disruption occurs on either segment, the LFS feature

will be activated and the LED will light to indicate that the entire

connection is down.
