Installation
CAUTION: Wear a grounding device and observe electrostatic discharge precautions
when setting the 4-position switch and the jumper and when installing the slide-inmodule media converter. 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 or
a similar device to set the recessed
switches (see the drawing to the
right).
1. Auto-Negotiation™
up Advertises 100 Mb/s full-duplex and half-duplex (only during Auto-
Negotiation). (See page 5.)
down Disable Auto-Negotiation.
2. Link Pass-Through
up Enable Link Pass-Through. (See page 6.)
down Disable Link Pass-Through.
3. AutoCross™
up Enable AutoCross™ - The media converter connects automatically to
either straight-through or crossover twisted-pair copper cable. (See
page 5.)
down Disable AutoCross™ - Either straight-through or crossover twisted-pair
copper cable must be installed, according to the site requirements.
4. (not used)
Set the Hardware/Software Jumper
The hardware/software jumper is located on the media converter circuit board. 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.

Install the Slide-In-Module
CAUTION: Wear a grounding device and observe electrostatic discharge precautions
when installing the CFETF10xx-110 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 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.
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
CFETF10xx-110 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.).

Connect the Fiber Cable
1. Locate or build 100Base-FX compliant fiber cable with male, two-stranded TX
to RX connectors installed at both ends.
2. Connect the fiber cables to the CFETF10xx-110 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.
Power the Media Converter
The slide-in-module media converter is powered through the Transition Networks
PointSystem™ chassis.

Operation
Status LEDs
The CFETF10xx-110 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 AC power.
FX On = A link has been established for the fiber connection.
Flashing = The fiber connection is receiving data.
TX On = A link has been established for the copper connection.
Flashing = The copper connection is receiving data.
Product Features
Auto-Negotiation™
The Auto-Negotiation feature allows the CFETF10xx-110 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 duplex capabilities
(full or half) to the other devices and negotiates the best mode of operation. AutoNegotiation 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 desired speed and duplex mode of operation.
AutoCross™
When the AutoCross feature is activated, it allows either straight-through (MDI) or
crossover (MDI-X) copper 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 if the copper cable is MDI or
MDI-X configuration.
Note: Factory default is “enable AutoCross.” Transition networks recommends
leaving the device in the “enable” mode.
