The two active pairs in a 10BaseT 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.
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.
1. Is the power LED on the media converter illuminated?
NO
• Is the power adapter the proper type of voltage and cycle frequency for your AC outlet?
NOTE: Refer to the “Power Supply Requirements” on the back page.
• Is the power adapter properly installed in the media converter and in the outlet?
• Contact Technical Support at [phone] or at (800) LAN-WANS.
YES
• Proceed to step 2.
2. Is the 10BaseT Link LED illuminated?
NO
• Check UTP cables for proper connection and pin assignment. (See below.)
• Contact Technical Support at [phone] or at (800) LAN-WANS.
YES
• Proceed to step 3.
2. Is the fiber Link LED illuminated?
NO
• Check fiber cables for proper connection.
• Verify that TX and RX cables on media converter are connected to RX and TX ports,
respectively, on the other 10BaseFL device.
• Contact Technical Support at [phone] or at (800) LAN-WANS.

• Be certain that the 10BaseT cable is
configured correctly (straight through or
crossover) for site installation.
• Verify that both the fiber products to be
connected are 10BaseFL or FOIRL compliant.
(The fiber port on the TRANSITION Networks
E-TBT-FRL-01 conforms to 10BaseFL or FOIRL
but NOT to 10BaseFB or FDDI.)
• 62.5/125 micron duplex fiber cable is
recommended.
• The maximum dBm loss for the fiber cable
should not exceed 13 dBm.
• Connect the power supply cable to the media
converter BEFORE connecting to the outlet.
• This unit must be installed with the PSU
provided. (Output 9 VDC regulated, 500 mA).
• Connecting more than two media converters in
series is not recommended.
