Converter 1

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: [phone]/(800) LAN-WANS.
YES• Proceed to step 2.
2. Are the RJ Link and FL Link LEDs illuminated?
NORJ 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:
http://www.transition.com
• Contact Technical Support: [phone]/(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: [phone]/(800) LAN-WANS.
YES• Contact Technical Support: [phone]/(800) LAN-WANS.
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.
