Enhanced 10/100Base-TX to 100Base-FX Converter
Link Fault Signaling (LFS)
LFS is a “nice to have” function that is extremely
beneficial in terms of network status monitoring. 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. The LFS function
monitors both copper and fiber segments giving a total
connection status report.
Set LFS to
ON
position for normal operational use.
Set LFS to
OFF
position when installing cables or
when testing the network connection.
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.
To appreciate the full 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 protocols. By
default, transmission of data will travel via the primary
link. Once a fault has been detected, transmission will
automatically be switched to the secondary link,
resulting in ‘non-stop’ network connectivity.
