In the example network installation below, the 8-Port Media Converter
provides cable connection and media conversion between a 10BASE-T
switch and remote fiber installations. Other 10BASE-T/10BASE-FL
installations are supported.
To install the 8-Port Media Converter:
1. Mount the 8-Port Media Converter in a 19-inch rack.
• Locate four (4) screws and clip-nuts if necessary (NOT included with
shipment).
• Carefully align 8-Port Media Converter with 19-inch rack rails.
• Install two (2) screws through each bracket into mounting rails.
2. Connect 10BASE-T cables.
• Locate 10BASE-T cables that comply with Ethernet™ 802.3 specifications
and that have male RJ-45 connectors installed at both ends.
• Referring to drawing above and to Configuring 10BASE-T Straight
Through/Crossover Cable Assembly on next page, be certain that the
10BASE-T cable is configured as straight through or crossover as required
for site installation. NOTE: An RJ-45 telephone cable is reverse-wired,
which is NOT the same as a crossover pinout.
3. Connect 10BASE-FL cables.
• Locate 10BASE-FL cables that comply with Ethernet™ 802.3 specifications
and that have two (2) male TX and RX connectors installed at both ends.
• Verify that the fiber products to be connected are 10BASE-FL or FOIRL
compliant. NOTE: Fiber ports on TRANSITION Networks fiber media
converters conform to 10BASE-FL or FOIRL but NOT to 10BaseFB or FDDI.
• Connect media converter TX connector to remote installation RX connector
and media converter RX connector to remote installation TX connector.
4. Connect to external AC power.
• Locate power cord included with shipment.
• Connect the power supply cable to the media converter BEFORE
connecting the power supply cable to the AC outlet.
1. Is the power LED on the media converter illuminated?
NO
• Is the power cord installed properly in the media converter
and in the outlet?
• Contact Technical Support: (800) 260-1312/(800) LAN-WANS.
YES
• Proceed to step 2.
2. Are the RJ Link and FL Link LEDs illuminated?
NO
RJ Link
• Check RJ connectors and UTP cables for proper connection
and pin assignment. (See below.)
NOTE: In the installation
drawing, connections between the switch and the Media Converters
are configured as straight through; the connection between the Media
Converter and the terminal is configured as crossover.
• Refer to Tech Tips available at:

• Contact Technical Support: (800) 260-1312/(800) LAN-WANS.
FL Link
• Verify that fiber cable is multimode (NOT single-mode).
• Check fiber cables for proper connection.
• Verify that TX and RX media converter cables are connected to
RX and TX ports, respectively, on remote 10BASE-FL device.
• Refer to Tech Tips available at:
http://www.transition.com
• Contact Technical Support: (800) 260-1312/(800) LAN-WANS.
YES

TROUBLESHOOTING SUGGESTIONS
If a Media Converter fails, ask the following questions:
INSTALLATION NOTES
Cable connections between a hub and the media converter must be configured as
straight through. Cable connections between the media converter and a terminal,
transceiver or NIC must be configured as crossover.
The two active pairs in a 10BASE-T 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 pins.
