3. Is the link/active LED on the main port lit (ON)?
NO:
a. Check that the RJ-45 cable is properly inserted into the bridging media
converter main port.
b. Check that the other cable end is inserted into an active device.
c. Check the cable for damage.
d. Contact Technical Support .
YES: Go to step 4.
4. Is there an RJ-45 cable inserted into the primary port on the bridging media
converter?
NO:
a. Insert the RJ-45 cable into the bridging media converter primary port.
b. Insert the other end of the cable into the input of an active device.
YES: Go to step 5.
5. Is the primary LED on the chassis lit (ON)?
NO:
a. Check that the RJ-45 cable is properly inserted into the primary port.
b. Check that the other end of the cable is properly inserted into an active
device.
c. Check the cable for damage.
d. Contact Technical Support.
YES: Go to step 6.
6. Is there an RJ-45 cable inserted into the backup port on the bridging media
converter?
NO:
a. Insert the RJ-45 cable into the bridging media converter backup port.
b. Insert the other end of the cable into the input of the an active device.
YES: Go to step 7.
7. Is the backup LED on the chassis lit (ON)?
NO:
a. Check that the RJ-45 cable is properly inserted into the backup port.
b. Check that the other end of the cable is properly inserted into an active
device.
c. Check the cable for damage.
c. Contact technical support.
YES: If the LED is ON and still no activity, contact technical support:
1.800.466.4526, then press "2."

Cable Specifications -- continued
Copper cable (10Base-T/100Base-TX) -- continued
10Base-T and the Ethernet collision domain:
• Refer to the 5-Segment Rule before installing half-duplex 10Base-T
cable.
• Installing full-duplex twisted-pair cable avoids collision domain
considerations—maximum distance 100 meters.
100Base-TX and the Fast Ethernet collision domain:
• Refer to the 512-Bit Rule before installing half-duplex 100Base-TX cable.
• Installing full-duplex twisted-pair cable avoids collision domain
considerations—maximum distance 100 meters.
Note: A Fast Ethernet collision domain can have only “1” Class “I” repeater or “2” Class
“II” repeaters.
Troubleshooting
If the SBFTF1010-130 fails or initially does not power up and function properly, ask the
following questions and take the suggested corrective actions.
1. Is the power LED on the bridging media converter ON?
NO:
a. Is the barrel connector from the external power supply fully inserted into
the bridging media converter?
b. Is the adapter plugged into an external power source?
c. Contact Technical Support: 1.800.466.4526, then press "2."
YES: Go to step 2.
2. Is there an active (connected to an output source) RJ-45 cable inserted into the
bridging media converter main port?
NO:
a. Insert an RJ-45 cable into the bridging media converter main port.
b. Insert the other cable end into an active device.
YES: Go to step 3.
