LNK link LED is not lit and the connection cannot be established 2 The LNK LED is lit and the connection is ok but cannot transmit or receive data 3 The converter functions properly for a while then it does not work And then it works after powering off and then on again 19 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 default 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
2. enabled devices Fiber Connections When connecting fiber cable to the Converter be sure the correct type ST or SC connector is used Follow the steps below to properly connect fiber cable 1 Remove and keep the ST SC port rubber covers When not connected to a fiber cable the rubber cover should be replaced to protect the optics 2 Check that the fiber terminators are clean You can clean the cable plugs by wiping them gently with a clean tissue or cotton ball moistened with a little ethanol Dirty fiber terminators on fiber optic cables will impair the quality of the light transmitted through the cable and lead to degraded performance on the port 3 Connect one end of the cable to the ST SC port on the Converter and the other end to the ST SC port on the other device 4 Check the corresponding port LED on the Converter to be sure that the connection is valid Refer to the LED chart Warning Because invisible laser radiation may be emitted from the aperture of the port when no cable is connected avoid exposure to laser radiation and do not stare into open apertures 14 LED Indicators Unit LEDs The Converter has following nine LEDS Power Indicator PWR This LED lights green when the Converter is receiving power from primary input Redundant Power Supply RPS This indicator lights green when the Converter is receiving power from redundant input Alarm ALM This indicator will light red and will
