Operation; Fault Isolation - Transition Networks CDFTF 10 Series User Manual

OPERATION

Using Status LEDs
Use the status LEDs to monitor the media
converter operation in the network.
PWR P(o)W(e)R Steady LED indicates
connection to external power.
TL1 T(wisted-pair) L(ink) 1: Steady
LED indicates a link on the
twisted-pair TELCO connection to
Converter #1.
FL1 F(iber) L(ink) 1: Steady LED
indicates a link on the fiber
connection to Converter #1.
AC1 AC(tivity) 1: Flashing LED
indicates activity on Converter #1.
TL2 T(wisted-pair) L(ink) 2: Steady LED indicates a link on the
twisted-pair TELCO connection to Converter #2.
FL2 F(iber) L(ink) 2: Steady LED indicates a link on the fiber
connection to Converter #2.
AC2 AC(tivity) 2: Flashing LED indicates activity on Converter #2.
Using SNMP*
Use SNMP at an attached terminal or at a remote location to:
• Monitor the media converter by monitoring:
Media Converter Power
Twisted-pair Link Status on Converter #1
Fiber Link Status on Converter #1
Activity on Converter #1
Twisted-pair Link Status on Converter #2
Fiber Link Status on Converter #2
Activity on Converter #2
• Enter network commands that:
Enable/disable Autocross

FAULT ISOLATION

and
If the media converter fails, isolate and correct the fault by determining the
answers to the following questions and then taking the indicated action:
Is the P(o)W(e)R LED on the media converter illuminated?
1.
NO
• Is the media converter inserted properly into the chassis?
• Is the power cord properly installed in the chassis and at the
external power source?
• Does the external power source provide power?
• Contact Technical Support: (800) 260-1312.
YES
• Proceed to step 2.
Is the T(wisted-pair) L(ink) 1 LED illuminated?
2.
NO
• Check the twisted-pair TELCO cables for proper connection.
• Ensure that the twisted-pair copper TELCO cable distance does NOT
EXCEED 60 meters.
• Contact Technical Support: (800) 260-1312.
YES
• Proceed to step 3.
Is the F(iber) L(ink) 1 LED illuminated?
3.
NO
• Check the fiber cables for proper connection.
• Verify that the TX and RX cables on media converter are connected
to RX and TX ports, respectively, on the other device.
• Contact Technical Support: (800) 260-1312.
YES
• Proceed to step 4.
4. Is the AC(tivity) 1 LED illuminated?
NO
• Verify that data is being sent from the external devices.
• Verify that all external devices are set to forced 100 Mb/s full-duplex
for full-duplex operation.
• Contact Technical Support: (800) 260-1312.
YES
• Proceed to step 5.
5. Is the T(wisted-pair) L(ink) 2 LED illuminated?
NO
• Check twisted-pair TELCO cables for proper connection.
• Ensure that the twisted-pair copper TELCO cable distance does NOT
EXCEED 60 meters.
• Contact Technical Support: (800) 260-1312.
YES
• Proceed to step 6.
