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 to, and failure of, the Media Converter.
4-Position Switch
The 4-position switch is located on
the side of the Media Converter. Use
a small flatblade screwdriver or a
similar device to set the recessed
switches (see the drawing to the right).
1. Auto-Negotiation
UP Advertises 100Mb/s full-duplex and half-duplex (see page 5).
DOWN Disables Auto-Negotiation. The Media Converter operates at 100
Mb/s in the duplex mode (full or half) of the attached device.
(This setting is primarily used when connecting to a hub).
2. Pause Control Frame
(Applies ONLY if switch 1 is UP AND the Media Converter is connected to
Auto-Negotiation device(s) capable of Pause Control Frame.)
UP Enables Pause Control (see page 6).
DOWN Disables Pause Control.
3. Link Pass-Through
UP Enables Link Pass-Through (see page 6).
DOWN Disables Link Pass-Through.
4. Far-End Fault
UP Enables Far-End Fault (see page 6).
DOWN Disables Far-End Fault.
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
Media Converter to link up, regardless of the cable configuration.
The jumper is located on the circuit board inside the Media Converter
housing. To set the jumper:
1. Using a small screwdriver, remove the four (4)
screws that secure the cover and carefully remove
the cover from the Media Converter.
2. Locate the J3 jumper on the circuit board and, using
small needle-nosed pliers or similar device, move the
jumper to the desired position (see the drawing to the
right).
3. Carefully replace the cover on the Media Converter and replace the four
(4) screws that secure the cover to the Media Converter.

Connect the Fiber Cable
1. Locate or build 100Base-FX compliant fiber cable with male, singlestranded simplex connectors installed at both ends.
2. Connect the simplex connector at one end of the cable to the singlestrand fiber port on the first E-100BTX-FX-05(10x) Media Converter.
3. Connect the simplex connector at the other end of the cable to the singlestrand fiber port on the second E-100BTX-FX-05(10x) Media Converter.
Connect the Twisted-Pair Copper Cable
1. Locate or build 100Base-TX compliant 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 E-100BTX-FX-05(10x) 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 adapter cord to the back of the Media Converter.
2. Connect the power adapter plug to AC power.
3. Verify that the Media Converter is powered by observing the illuminated
LED power indicator light.
DC
Consult the User’s Guide for the Transition Networks SPS1872-xx DC External
Power Suppy for powering the Media Converter.

Operation
Status LEDs
The E-100BTX-FX-05(10x) Media Converter is designed to operate without
user intervention. Use the status LEDs to monitor the Media Converter
operation in the network.
Power On Connection to external AC power.
SDF On (Singal Detect/Fiber) A link has been established for
the Fiber connection.
SDC On (Signal Detect/Copper) A link has been established for
the Copper connection.
RXC Flashing (Copper Receive) The Copper connection is receiving
data.
RXF Flashing (Receive Fiber) The Fiber connection is receiving data.
Product Features
Auto-Negotiation
The Auto-Negotiation feature brings up the copper links in the highest speed
and mode possible for all the attached network devices.
NOTE: The E-100BTX-FX-05(10x) series Media Converter does NOT support
rate conversion between 10Mb/s, 100Mb/s, and 1000Mb/s network devices.
Pause Control Frame
The Pause Control Frame 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 Control feature is present on ALL network devices
attached to the Media Converter(s), enable the Pause Control feature on the
Media Converter(s). Otherwise, disable the Pause Control feature (see page 2).

Link Pass-Through
When the Link Pass-Through feature is activated (see page 2), a fault on one
side of the Media Converter stops the signal and data transmission on the
other side of the Media Converter. If the Media Converter does not detect a
good link on the copper side, the Media Converter disables all transmission
(including active-idle) on the fiber side.
Far-End Fault
When the Far-End Fault feature is activated (see page 2), a fault on an
incoming fiber link causes the Media Converter to transmit a Far-End Fault
signal on the outgoing fiber link. 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.
