• Converts 10/100 on copper to straight 100 on fiber.

• Supports Half or Full-Duplex on both ports.

• Is fully manageable.

• Features Auto-Negotiation and AutoCross™.

• Includes Link Pass Through (LPT) and Far-End-Fault (FEF).

• Provides Automatic Link Restoration.

• Has Field Upgradeable Firmware.

• Can be used with any Point System™ Chassis.

• The bridging media converters provide conversion and integration solutions for half- and full-duplex environments.

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

** CBFTF1029-105 and CBFTF1029-106 are intended to be installed in the same network where one is the local converter and the other is the remote converter.

The 6-position DIP switch (SW2) is located on the edge of the PCB. Use a small flat blade screwdriver to set the switches. Before setting the switch, wear a grounding device and observe electrostatic discharge precautions.

Switch 1: TP Auto-Negotiation

• UP = Enables Auto-Negotiation on the copper port. Advertises the setting of switches 2 and 3.

• DOWN = Disables Auto-Negotiation on the copper port. Forces the setting of switches 2 and 3.

Switch 2: TP Speed (only functions when Switch 1 is Down)

• UP = 100 Mb/s operation on the copper port.

• DOWN = 10 Mb/s operation on the copper port.

Switch 3: TP Duplex (Copper Mode) (only functions when Switch 1 is Down)

• UP = Full duplex operation on the copper port.

• DOWN = Half duplex operation on the copper port.

For parallel detection (only with Auto-Negotiation enabled and linked to a non-negotiating device):

• UP = Parallel detects in IEEE standard half duplex.

• DOWN = Non-standard full duplex.

Switch 4: Fiber Mode

• UP = Forces full duplex operation on the fiber port.

• DOWN = Forces half duplex operation on the fiber port.

Switch 5: Fiber Far-End Fault (FEF)

• UP = FEF Enabled.

• DOWN = FEF Disabled.

Switch 6: Link Pass Through (LPT)

• UP = LPT Enabled.

• DOWN = LPT Disabled.

The Hardware/Software jumper (J4) is located on the media converter circuit board and is labeled “H” for hardware and “S” for software. Use a small needlenosed pliers or a similar tool to set the jumper.

• Software Mode: The media converter mode is determined by the most-recently saved on-board settings.

• Hardware Mode: The media converter mode is determined by the 6-position DIP switch (SW2) settings.

To install the slide-in module, follow these steps:

1. Locate an empty installation slot on the PointSystem™ chassis.

2. Carefully slide the module into the installation slot, aligning the module with the installation guides.

3. Ensure that the module is firmly seated inside the chassis.

4. Push in and rotate the panel fastener screw to secure the module to the chassis front.

The AutoCross feature allows either MDI (straight-through) or MDI-X (crossover) cable connections to be configured automatically.

1. Locate or build an IEEE 803.2 compliant 10Base-T or 100Base-TX cable 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 (e.g., switch, workstation).

1. Locate an 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 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.

The status LEDs monitor the media converter’s operation:

• FDPX (Fiber Duplex):

◦ ON = Full duplex fiber connection.

◦ OFF = Half duplex fiber connection.

• FLNK (Fiber Link):

◦ ON = Fiber link connection.

◦ Blinking = Fiber network activity.

• PWR (Power):

◦ ON = Power applied to chassis card.

• TSPD (Twisted-Pair Speed):

◦ ON = 100 Mb/s.

◦ OFF = 10 Mb/s.

• TDPX (Twisted Pair Duplex):

◦ ON = Full duplex copper connection.

◦ OFF = Half duplex copper connection.

• TLNK (Twisted Pair Link):

◦ ON = Copper link connection.

◦ Blinking = Copper network activity.

AutoCross™

This feature detects and configures the twisted-pair copper port to the correct straight-through (MDI) or crossover (MDI-X) configuration. This allows either MDI or MDI-X cable to connect the media converter to devices such as hubs, transceivers, or network interface cards (NICs) without operator intervention.

Link Pass-Through (LPT)

LPT allows the media converter to monitor both the fiber and copper RX (receive) ports for loss of signal. If a loss of an RX signal occurs, the media converter will automatically disable the corresponding TX (transmit) signal, thus “passing through” the link loss to the far-end device. This prevents the loss of valuable data unknowingly transmitted over an invalid link. When an LPT condition occurs, the Link/Activity LED for the port that still has a link up but is being forced down will blink on and off every 2 seconds.

Far-End Fault (FEF)

When a fault occurs on an incoming fiber link, the media converter transmits a Far-End Fault signal on the outgoing fiber link. This signal also activates Link Pass-Through, which in turn disables the link on the copper portion of the network.

Auto-Negotiation

This feature allows the media converter to automatically configure itself to achieve the best possible mode of operation over a link. It broadcasts its speed (10 Mb/s or 100 Mb/s) and duplex capabilities (full or half) to other devices and negotiates the best mode. You can disable Auto-Negotiation to force the connection to the best mode of operation, which is useful when linking to a non-negotiating device.

Parallel Detection

This is used when an auto-negotiating port detects a link partner in forced mode. It can be set to the IEEE Standard half duplex or non-standard full duplex. Per the IEEE method, the port drops to the detected speed (10Mbs or 100Mbs) and defaults to HALF DUPLEX. The media converter allows bypassing this by setting the parallel detection default mode to half or full duplex via DIP switch 3.

Using SNMP with Transition Networks FocalPoint™ software allows for remote monitoring of the converter.

If the media converter fails, isolate and correct the fault by following these steps:

1. Is the PWR (power) LED lit?

• NO:

◦ Is the power cord properly installed in the media converter and at the external power source?

◦ Does the external power source active?

◦ If issues persist, contact Technical Support.

• YES:

◦ Proceed to step 2.

2. Is the TLNK (copper link) LED lit?

• NO:

◦ Check the copper cables for proper connection and pin assignment.

◦ If issues persist, contact Technical Support.

• YES:

◦ Proceed to step 3.

3. Is the FLNK (fiber-pair link) LED lit?

• NO:

◦ Check the fiber cables for proper connection.

◦ Verify that the TX and RX cables are connected to the RX and TX ports, respectively on the 100Base-FX device.

◦ If issues persist, contact Technical Support.

• YES:

◦ Proceed to step 4.

4. Is the TPSD (twisted-pair speed) LED lit?

• NO (LED is Off):

◦ This means the media converter has selected 10Mb/s operation.

◦ Check the copper cables for proper connection.

◦ If the speed is not correct, disconnect and reconnect the twisted pair cable to restart the initialization process.

◦ If issues persist, contact Technical Support.

• YES (LED is On):

◦ This means the media converter has selected 100Mb/s operation.

◦ If the speed is not correct, disconnect and reconnect the twisted pair cable to restart the initialization process.

◦ If issues persist, contact Technical Support.
