User’s Guide

CBFTF10xx-10x

Slide-in-Module Media Converter

• Copper to Fiber

• 10/100 Bridging (2-Port)

• 10/100Base-TX to 100Base-FX

The CBFTF10xx-10x 2-port Ethernet/fast Ethernet
bridging media converter is designed to be
installed in a Transition Networks PointSystem™
chassis and connects 10Base-T Ethernet or
100Base-TX fast Ethernet twisted-pair copper
network devices to network devices on a 100Base­FX fast Ethernet fiber network.

*Typical maximum cable distance. Actual distance is dependent upon the physical
characteristics of the network installation.

The stand-alone version of the media
converter is SBFTF10xx-10x. For more
information, see the SBFTF10xx-10x user’s
guide on-line at: www.transition.com.

Installation

Set the Configuration Switches

The configuration switches are located on the circuit board of the media
converter. Use a flat-blade screwdriver or a similar device to set each switch.

NOTE:

• Switches 1, 2, 3, and 5 apply to the copper port.

• Switch 4 applies to the fiber port.

• Switch 6 applies to the media converter.

1. Twisted-Pair Auto-Negotiation

UP (Enabled) - The media converter

“advertises” ALL rate and mode capabilities to
the network:

• 100Mb/s full-duplex,

• 100Mb/s half-duplex,

• 10Mb/s full-duplex, and

• 10Mb/s half-duplex.

DOWN (Disabled) - The bridging media converter does not “advertise” the rate
and mode capabilities to the network. Switch #2 and switch #3 are then used to
set the twisted-pair rate and mode.

2. Twisted-Pair Rate

UP - Sets the twisted-pair rate to 100Base-TX.

DOWN - Sets the twisted-pair rate to 10Base-T.

4. Fiber Mode

UP (Full-Duplex) - The fiber cable distances are

constrained by the cable requirements (see pages 1
and 2).

DOWN (Half-Duplex) - The fiber cable distances are
constrained by the 512-Bit Rule (see page 10).

5. AutoCross

UP (Enable) - The media converter connects

automatically to either straight-through or crossover
twisted-pair copper cable.

DOWN (Disable) - Either straight-through or
crossover twisted-pair copper cable must be
installed, according to the site requirements.

6. Link Pass-Through

UP (Enable) - When Link Pass-Through is enabled, a

fault on one side of the media converter stops the
signal and data transmission on the other side.

DOWN (Disable) - When Link Pass-Through is
disabled, a fault on one side of the media converter
does not stop the signal and data transmission on
the other side.

3. Twisted-Pair Mode

UP (Full-Duplex):

The twisted-pair cable distances are constrained by
the cable requirements (see pages 1 and 2).

DOWN (Half-Duplex):

At the 100Base-TX rate, the twisted-pair cable
distances are constrained by the 512-Bit Rule (see
page 9).

At the 10Base-T rate, the twisted-pair cable
distances are constrained by the 5-Segment Rule
(see page 10).

Install the Slide-in-Module

1. Carefully slide the slide-in-module into two adjacent installation slots,
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 to the chassis front.

Install the Copper and Fiber Cables

• For 10Base-T, half-duplex mode, refer to the 5-Segment Rule (page 10)
before installing the 10Base-T twisted-pair copper cable.

• For 100Base-TX, half-duplex mode, refer to the 512-Bit Rule (page 10)
before installing the 100Base-TX twisted-pair copper cable.

• For 100Base-FX, half-duplex mode, refer to the 512-Bit Rule (page 9)
before installing the 100Base-FX fiber cable.

• For full-duplex mode, the 512-Bit Rule does not apply. The cable lengths
are constrained by the cable requirements (see pages 1 and 2).

NOTE: A fast Ethernet collision domain can have one one class I repeater or
two class II repeaters.

Installation - Continued

Set the Hardware/Software Jumper

The hardware/software jumper is located on the circuit
board and is labeled “H” and “S”. Use a pair of needle­nose pliers to set the jumper to the desired location.

Hardware The media converter settings are determined

by dip switch settings (p. 3-5).

Software The media converter settings are determined

by the most-recently saved, on-board
microprocessor settings.

Twisted-Pair Copper Cable

NOTE: The AutoCross feature allows either MDI (straight-through) or MDI-X

(crossover) cable connections to be configured automatically, according to
the network conditions.

1. Locate or build IEEE 803.2™ compliant 10Base-T or 100Base-TX cables,
with 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 CBFTF10xx-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.).

Installation - Continued

Fiber Cable

1. Locate or build IEEE 803.2™ compliant 100Base-FX fiber cable with
male, two-stranded TX to RX connectors installed at both ends.

2. Connect the fiber cables to the CBFTF10xx-10x 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.
