Installation
CAUTION: Wear a grounding device and observe electrostatic discharge
precautions when setting the 4-position switch and the jumpers. Failure to
observe this caution could result in damage to, and subsequent failure of, the
media converter.
Set the 4-Position Switch
• The 4-position switch is
located on the circuit board.
• Use a small flat-blade
screwdriver to set the
recessed switches.
1. Auto-Negotiation
up = Advertises 100 Mb/s full-duplex and half-duplex (only during
Auto-Negotiation). See page 5.
down = Disables Auto-Negotiation. Operates at 100 Mb/s in the mode
(either full- or half-duplex) of the attached device.
2. Pause
Applies only if switch “1” is up and the media converter is connected to
Auto-Negotiation device(s) capable of pause control frame.
up = Allows negotiation of pause control frame. See page 6.
down = Does not allow negotiation of pause control frame.
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.
Set the hardware/software jumper
• The jumper is located on the circuit board (labeled “H” and “S”).
• Use small needle-nosed pliers or a similar device to set the jumper.
• Refer to the drawings below when setting the media converter for
hardware or software mode.
Hardware The media converter mode is determined
by the 4-position switch settings listed
above.
Software The media converter mode is determined
by the most-recently saved, on-board
microprocessor settings.

Installation -- Continued
Set the AutoCross™ jumper
When the AutoCross feature is activated, it allows either straight-through or
crossover cables to be used when connecting to 100Base-TX devices.
AutoCross determines the characteristics of the connection and automatically
configures the unit to link up, regardless of the cable configuration.
• The jumper is located on the circuit board and is labeled “D” and “E”.
• Use a small needle-nose pliers to set the recessed switches.
Disable Either straight-through or crossover
twisted-pair copper cable must be
installed, according to the site
requirements.
Enable The media converter connects
automatically to either straight-through
or crossover twisted-pair copper cable.
Note: Factory default is “enable AutoCross.” Transition networks
recommends leaving the device in the “enable” mode.
Install the slide-in-module
CAUTION: Wear a grounding device and observe electrostatic discharge
precautions when installing the CFETF1029-2xx slide-in-module media
converter. Failure to observe this caution could result in damage to, and
subsequent failure of, the media converter.
1. Carefully slide the slide-in-module into the installation slot, aligning the
module with the installation guides.
2. Ensure that the slide-in-module is firmly seated inside the chassis.
3. Push in and rotate the attached panel fastener screw clockwise to secure
the module to the chassis front.

Installation -- Continued
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 CFETF1029-2xx media converter.
3. Connect the simplex connector at the other end of the cable to the singlestrand fiber port on the second CFETF1029-2xx 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 CFETF1029-2xx 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
The slide-in-module media converter is powered through the Transition
Networks PointSystem™ chassis.
Connect the fiber cable
to the first media
converter as shown.

Operation
Status LEDs
The CFETF1029-2xx media converter is designed to operate
without user intervention. Use the status LEDs to monitor the
media converter operation in the network.
PWR On = Connection to external power.
LKF On = The fiber link has been established.
LKC On = The copper link has been established.
RXF Flashing = The fiber link is receiving data.
RXC Flashing = The copper link is receiving data.
Product features
Auto-Negotiation
The Auto-Negotiation feature allows the CFETF1029-2xx media converter to
automatically configure itself to achieve the best possible mode of operation
over a link. The media converter broadcasts its speed 100 Mb/s and full or
half duplex capabilities to the other devices and negotiates the best mode of
operation. Auto-Negotiation allows quick and easy installation because the
optimal link is established automatically. No user intervention is required to
determine the best mode of operation.
A scenario where the media converter is linked to a non-negotiating device is
a case where the user may want to disable Auto-Negotiation. In this instance,
the mode of operation will drop to the least common denominator between
the two devices (e.g. 100 Mb/s, half-duplex). Disabling this feature gives the
user the ability to force the connection to the best mode of operation.
Half-duplex network (512-Bit Rule)
In a half-duplex network, the maximum cable lengths are determined by the
round trip delay limitations of each Fast Ethernet collision domain. (A collision
domain is the longest path between any two terminal devices, e.g. a terminal,
switch, or router.)
The 512-Bit Rule determines the maximum length of cable permitted by
calculating the round-trip delay in bit-times (BT) of a particular collision
domain. If the result is less than or equal to 512 BT, the path is good.
For more information on the 512-Bit Rule, see the white paper titled
“Collision Domains” on the Transition Networks website at:
www.transition.com.
