FAULT ISOLATION and CORRECTION
If a bridging media converter fails, ask the following questions and then
taking the indicated action:
1.
Is the P(o)W(e)R LED on the E-PSW-FX-03 illuminated?
NO
•
Is the power adapter the proper type of voltage and cycle
frequency for the AC outlet?
•
Is the power adapter properly installed in the media
converter and in the
grounded AC
outlet?
•
Does the grounded AC outlet provide power?
•
Contact Technical Support: (800) 260-1312.
YES
•
Continue at step 2.
2.
Is the Link LED illuminated on a port with twisted-pair installed?
NO
•
Check UTP cables for proper connection/pin assignment.
•
Ensure that terminal device(s) is/are powered.
•
Disconnect and reconnect the copper cable to restart the
initialization process.
•
Restart the terminal device(s) to restart the initialization process.
•
Contact Technical Support: (800) 260-1312.
YES
•
Proceed to step 3.
3.
Is the Link LED illuminated on a port with fiber installed?
NO
•
Check fiber cables for proper connection.
•
Verify that TX and RX cables are connected to RX and TX ports,
respectively, on 100BASE-FX device.
•
Ensure that terminal device(s) is/are powered.
•
Disconnect and reconnect the fiber cable to restart the initialization
process.
•
Restart the terminal device(s) to restart the initialization process.
