Introduction
Transition Networks E-100BTX-FX-05 Fast Ethernet media converters connect 100Base-TX shielded or
unshielded twisted-pair copper cable to 100Base-FX fiber-optic cable. The E-100BTX-FX-05 series media
converters include both Standard temperature models and Extended temperature models.
Standard Temperature Models: media converters that can be used in a standard temperature
environment from 0°C to 50°C (32°F to 122°F)
Extended Temperature Models: media converters with the “HT” extension in the part number can be
used in an extended temperature environment from -25°C to 65°C (-13°F to 149°F).

Installation
CAUTION: Wear a grounding device and observe electrostatic discharge precautions when setting the
4-position DIP switch and jumpers. Failure to observe this caution could result in failure of the media
converter.
4-Position DIP Switch
The 4-position DIP switch is located on the side of the media converter. Use a small flat-blade screwdriver
or a similar tool to set the recessed switches.

AutoCross Jumpers
The AutoCross feature allows either straight-through (MDI) or crossover (MDI-X) cables to be used when
connecting to devices such as hubs, transceivers, or network interface cards (NICs). AutoCross
determines the characteristics of the cable connection and automatically configures the unit to link up,
regardless of the cable configuration.
High Temperature Board, J3, 3-Pin Header Settings
1. Orient the board as shown below.
2. Position the jumper as shown below.
Standard Temperature Board, J1, 3-Pin Header Settings
1. Orient the board as shown below.
2. Position the jumper as shown below.

Installing the Fiber Cable
1. Locate a 100Base-FX compliant fiber cable with male, two-stranded TX to RX connectors installed at
both ends.
2. Connect the fiber cables to the media converter as described:
• Connect the male TX cable connector to the female TX port.
• Connect the male RX cable connector to the female RX port.
3. Connect the fiber cables to the other device (another media converter, hub, etc.) as described:
• Connect the male TX cable connector to the female RX port.
• Connect the male RX cable connector to the female TX port.
Installing the Copper Cable
1. Locate a 100Base-TX compliant copper cable with male, RJ-45 connectors installed at both ends.
2. Connect the RJ-45 connector at one end of the cable to the RJ-45 port on the media converter.
3. Connect the RJ-45 connector at the other end of the cable to the RJ-45 port on the other device
(switch, workstation, etc.).

Powering the media converter
AC
1. Install the power cord barrel connector into the back of the media converter.
2. Connect the power adapter plug into AC power.
3. Verify that the media converter is powered up by observing the illuminated power indicator LED.
DC
Consult user guide 33455 for information on the SPS-2460-xx DC external power supply.

Operation
Status LEDs
Use the status LEDs to monitor the E-100BTX-FX-05 media converter operation in the network:
Power (Power) On = Connected to external AC power.
SDF (Signal Detect/Fiber) On = Fiber link is detected.
SDC (Signal Detect/Copper) On = Copper link is detected.
RXC (Receive/Copper) Flashing = A signal is being received on the copper link.
RXF (Receive/Fiber) Flashing = A signal is being received on the fiber link.
Auto-Negotiation
When the Auto-Negotiation feature is activated, the media converter configures itself to achieve the best
possible mode of operation over a link, automatically. The media converter broadcasts its speed (100
Mb/s) and duplex capabilities (either fullor half-duplex) and negotiates the best mode of operation
between the two devices.
Pause Control
The Pause feature can improve network performance by allowing one end of the link to signal the other to
discontinue frame transmission for a set period of time to relieve buffer congestion.
Note: If the Pause feature is available on ALL network devices attached to the media converter(s), enable
the Pause feature on the media converter(s); otherwise, disable the Pause feature.
Link Pass-Through
The Link Pass-Through feature allows the media converter to monitor both the fiber and copper RX
(receive) ports for loss of signal. In the event of a loss of an RX signal (1), the media converter will
automatically disable the TX (transmit) signal (2), thus, “passing through” the link loss (3). The far-end
device is automatically notified of the link loss (4), which prevents the loss of valuable data unknowingly
transmitted over an invalid link.

Far-End Fault
When a fault occurs on an incoming fiber link (1), the media converter transmits a Far-End Fault signal on
the outgoing fiber link (2). In addition, the Far-End Fault signal also activates the Link Pass-Through,
which in turn disables the link on the copper portion of the network (3) and (4).
