The TRANSITION Networks J/E-CF-01 10BASE-T/10BASE-FL media
converters connect either unshielded or shielded 10BASE-T twisted-pair
copper to 10BASE-FL multimode fiber.
For network installation, the J/E-CF-01 media converter provides an RJ-45
twisted pair connector and a set of RX (receive) and TX (transmit) ST
connectors to 850 nm multimode fiber-optic cable.
CAUTION: RJ connectors are NOT INTENDED FOR CONNECTION TO THE
PUBLIC TELEPHONE NETWORK. Failure to observe this caution could result in
damage to the public telephone network.

Twisted pair connection requires two active pairs configured as straight
through or crossover. The two active pairs in an Ethernet™ network are
pins 1 & 2 and pins 3 & 6. Use only dedicated wire pairs (such as
blue/white & white/blue, orange/white & white/orange) for the active pairs.
INSTALLATION
Install Cable
NOTE: See page 6 for cable specifications and configurations.
COPPER
NOTE: KEEP TWISTED PAIR RUNS AS SHORT AS POSSIBLE.
CABLE CONNECTIONS BETWEEN A HUB AND THE MEDIA
CONVERTER MUST BE CONFIGURED AS CROSSOVER . CABLE
CONNECTIONS BETWEEN THE MEDIA CONVERTER AND A
TERMINAL, TRANSCEIVER OR NIC MUST BE CONFIGURED AS
STRAIGHT THROUGH.
• Locate or build 10BASE-T compliant cables with straight-through
or crossover configuration and with male RJ-45 plug connectors.
• Connect male RJ-45 plug connector at one end of cable to Media
Converter RJ-45 jack connector.
• Connect male RJ-45 plug connector at other end of cable to
10BASE-T terminal device RJ-45 jack connector (using straightthrough cable configuration) or to 10BASE-T hub RJ-45 jack
connector (using crossover cable configuration).
FIBER
• Locate or build 10BASE-FL compliant fiber cable with male twostranded TX to RX connectors at both ends.
• Connect male TX and RX cable connectors at one end of cable to
TX and RX female connectors, respectively, on Media Converter.
• Connect male TX and RX cable connectors at other end of cable
to RX and TX connectors of 802.3 compliant fiber device.
Connect to Power

OPERATION
After installation, the media converter should function without operator
intervention.
Status LEDs
Use the status LEDs to monitor media converter operation in the network.
LINK (10BASE-T) Dark LED indicates lack of power.
Steady green LED indicates normal
operation.
One (1) blink indicates Link Down.
Five (5) blinks indicates Polarity Reversal.
ACTIVITY (10BASE-T) Flashing amber LED indicates 10BASE-T
activity.
LINK (10BASE-FL) Dark LED indicates lack of power.
Steady green LED indicates normal
operation.
One (1) blink indicates
Link Down.
ACTIVITY (10BASE-FL) Flashing amber LED indicates 10BASE-FL
activity.
FAULT ISOLATION and CORRECTION
If the media converter fails, isolate and correct the fault by determining the
answers to the following questions and then taking the indicated action:
1. Are ANY LEDs on the media converter illuminated?
NO
• Is the power adapter the proper voltage and frequency for AC
outlet? NOTE: Refer to “Power Supply Requirements” on page 7.
• Is the power adapter properly installed in the media converter and
in the outlet?
• Contact Technical Support: (800) 260-1312/(800) LAN-WANS.
YES
• Proceed to step 2.
2. Does the green10BASE-T LINK
LED blink once* and go off?
YES
• Check twisted pair cables for proper connection.
• Check straight-through/crossover cable configuration.
• Contact Technical Support: (800) 260-1312/(800) LAN-WANS.
NO
• Proceed to step 3.
3. Does the green10BASE-FL LINK LED blink once and go off?
YES
• 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/(800) LAN-WANS.
NO
• Proceed to step 4.
4. Is the amber 10BASE-T ACTIVITY LED illuminated?
NO
• Restart the workstation to restart the initialization process.
• Contact Technical Support: (800) 260-1312/(800) LAN-WANS.
YES
• Proceed to step 5.
5. Is the amber 10BASE-FL ACTIVITY LED illuminated?
NO
• Restart the workstation to restart the initialization process.
• Contact Technical Support: (800) 260-1312/(800) LAN-WANS.
YES
• Contact Technical Support: (800) 260-1312/(800) LAN-WANS.
*If 10BASE-T Status LED blinks 5 times, media converter is detecting and
automatically correcting polarity reversal in 10BASE-T cable. No action is
necessary.
