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

AutoCross™ Jumper
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.
NOTE: AutoCross is enabled by default, the recommended state.
The jumper is located on the media converter’s circuit board To set the
jumper:
1. Using a small screwdriver, remove the four (4) screws that secure the
cover; then remove the cover from the media
converter.
2. Locate header J3 on the circuit board; using a small
needle-nosed pliers move the jumper to the desired
position. (Refer to the drawing to the right.)
3. Carefully replace the cover, and then replace the
four (4) screws to secure the cover to the media
converter.

Installation -- Continued
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.
Connect fiber cable
to media converter
as shown.

TX
Installing the copper cable
1. Locate or build 100Base-TX compliant copper cables 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.).

Power 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 by observing the illuminated
LED power indicator light.
DC
Consult user guide 33266 for information on the SPS-1872-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 = Connection 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 full- or half-duplex) and negotiates the best mode of
operation between the two devices.
