FAULT ISOLATION and CORRECTION

If the multi-port media converter fails, isolate and correct the fault by
determining the answers to the following questions and then taking the
indicated action:
1. Is the POWER LED on the multi-port media converter
illuminated?
NO
• Is the power cord 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
• Proceed to step 2.
2. Are any of the 10BASE-T T(wisted)P(air) LEDs illuminated?
NO
• Check twisted pair cables for proper connection.
• Contact Technical Support: (800) 260-1312.
YES
• Proceed to step 3.
3. Are any of the 10BASE-FL F(i)B(e)R LEDs illuminated?
NO
• Check fiber cables for proper connection.
• Verify that TX and RX cables on media converter are connected to
RX and TX ports, respectively, on other device.
• Contact Technical Support: (800) 260-1312.
YES
• Proceed to step 4.
4. Are any of the ACT(ivity) LEDs illuminated?
NO
• Disconnect and reconnect the cable to restart the initialization
process.
• Restart the workstation to restart the initialization process.
• Contact Technical Support: (800) 260-1312.
YES
• Contact Technical Support: (800) 260-1312.

Set LinkAlert Switches
USING LINKALERT™
NOTE: The E-TBT-FRL-xx00 series multi-port media converter LinkAlert
feature allows each media converter port to pass 10BASE-T side link faults
over the port link to the 10BASE-FL side and to pass 10BASE-FL side link
faults over the port link to the 10BASE-T side.
LINK FAULT INDICATION
10BASE-T Media Converter
Device
If the port does not detect a good link on the 10BASE-T side, the port disables
all transmission (including active-idle) on the 10BASE-FL side.

SWITCH SETTINGS

Use the 2-position switches at the front of the E-TBT-FRL-xx00 to
™
enable/disable LinkALERT for three contiguous media converter ports.

SWITCH 1 enables or disables LinkAlert
SWITCH 2 for ports 4 - 6. SWITCH 3 enables or disables
™
LinkAlert for ports 7 -9 in a 12-port unit and SWITCH 4 for
ports 10 -12.

NOTE: Refer to page 10 for cable and connector specifications.
COPPER
1. Locate or build 10BASE-T compliant cables with male RJ-45 plug
connectors at both ends.
2. Connect male RJ-45 plug connector at one end of cable to media
converter port RJ-45 jack connector.
3. Connect male RJ-45 plug connector at other end of cable to
10BASE-T device RJ-45 jack connector.
