FCC Regulations
This equipment has been tested and found to comply with the limits for a class A digital device, pursuant
to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment. This equipment generates,
uses, and can radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference, in which case the user will be
required to correct the interference at the user’s own expense.
Canadian Regulations
This digital apparatus does not exceed the Class A limits for radio noise for digital apparatus set out on
the radio interference regulations of the Canadian Department of Communications.
Le présent appareil numérique n'émet pas de bruits radioélectriques dépassant les limites applicables
aux appareils numériques de la class A prescrites dans le Règlement sur le brouillage radioélectrique
édicté par le ministère des Communications du Canada.

Converter Chassis, C/E-R-TX-FX-01 series redundant Fast Ethernet
™ media converters
connect 100BASE-TX unshielded twisted pair copper to 1300 nm 100BASE-FX
multimode OR to 1300 nm 100BASE-FX singlemode fiber. In the event of a failure
in the primary copper or fiber connection, a fully redundant secondary connection
is made available to the failed copper or fiber connection. Also, the copper and
fiber media converter interfaces operate independently, so that a failure on one
interface will not force a failure on the other interface.
Switches at the side of the media converter allow selection of auto-negotiation and
of full/half-duplex. Also, a port select timer (PST) switch* allows the network
administrator to set different timer values (used when a primary connection is lost
and a secondary connection is made) at each end of the copper/fiber interface.

FAULT ISOLATION and CORRECTION
If the media converter fails, isolate and correct the failure by determining the
answers to the following questions and then taking the indicated action:
1. Are the PRI(mary)/SEC(ondary) LEDs on the media converter
illuminated or alternating between between primary and
secondary ports?
NO
• Is the power adapter the proper type of voltage and cycle frequency
for AC outlet?
NOTE: Refer to the “Power Supply Requirements” on page 7.
• Is the power adapter properly installed in the media converter and
in the outlet?
• *Are PST switch settings on two media converters installed in series
in the network set to different values?
• Contact Technical Support at (800) 260-1312/ (800) LAN-WANS.
YES
• Proceed to step 2.
2. Is the 100BASE-TX SDC (Signal Detect/Copper) LED
illuminated?
NO
• Check UTP cables for proper connection.
• Verify MDI/MDI-X switch position.
• Contact Technical Support at (800) 260-1312/ (800) LAN-WANS.
YES
• Proceed to step 3.
3. Is the 100BASE-FX SDF (Signal Detect/Fiber) 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 100BASE-FX device.
• Refer to Tech Tips available at: http://www.transition.com
• Contact Technical Support at (800) 260-1312/ (800) LAN-WANS.
YES
• Contact Technical Support at (800) 260-1312/ (800) LAN-WANS.
*NOTE: Setting PST switch settings on two media converters installed in series
in the network to different values (11 seconds and 5 seconds) ensures, in the
event of common power failure or similar incident, a sufficient delay in the time
required to establish each link so that communication between the media
converters is guaranteed.
