*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 recessed switches. Below are the individual switch settings:

1. 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.

2. 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.

3. Copper Mode Duplex (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 non-negotiating device):

• UP: Parallel detects in IEEE standard half duplex.

• DOWN: Non-standard full duplex.

4. Fiber Mode

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

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

5. Far-End Fault (FEF)

• UP: FEF Enabled

• DOWN: FEF Disabled

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: Set the jumper to the “S” position. The media converter mode is determined by the most-recently saved on-board settings.

Hardware Mode: Set the jumper to the “H” position. The media converter mode is determined by the 6-position DIP switch settings.

To install the media converter slide-in module:

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. Follow these steps to install the copper cable:

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 TRANSITION NETWORKS CBFTF1013-105 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.).

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.

Use the status LEDs to monitor media converter operation in the network.

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.

The AutoCross feature detects and configures the twisted-pair copper port on the TRANSITION NETWORKS CBFTF1013-105 to the correct straight-through (MDI) or crossover (MDI-X) configuration. This feature 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.

The Link Pass-Through (LPT) feature allows the media converter to monitor both the fiber and copper RX (receive) ports for loss of signal. In the event of a loss of an RX signal, the media converter will automatically disable its corresponding TX (transmit) signal, thus, “passing through” the link loss. The far-end device is automatically notified of the link loss, which 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 would have a link up condition, but is being forced into a link down, blinks on and off every 2 seconds while the LPT condition exists.

When a fault occurs on an incoming fiber link, the media converter transmits 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.

The Auto-Negotiation feature allows the media converter to automatically configure itself to achieve the best possible mode of operation over a link. The media converter will broadcast its speed (10 Mb/s or 100 Mb/s) and duplex capabilities (full or half) 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. In a scenario where the media converter is linked to a non-negotiating device, you 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 lets you force the connection to the best mode of operation.

Parallel detection is the method used to link when an auto negotiating port detects a link partner that is in forced mode and therefore cannot participate in the auto negotiating process. Parallel Detection can be set to IEEE Standard half duplex, or the non-standard full duplex. Switch settings for parallel detection are valid in hardware or software mode, only when Auto-Negotiation is enabled. Per the IEEE method, an auto negotiating port that detects a forced link partner should drop to the detected speed (10Mbs or 100Mbs) and default to HALF DUPLEX. The TRANSITION NETWORKS CBFTF1013-105 allows bypassing the IEEE method by setting the parallel detection default mode to half or full duplex via DIP switch 3.

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.

You can use SNMP at an attached terminal or at a remote location to monitor the converter by monitoring:

• Media converter power

• Serial and part number

• Port number

• Copper and fiber link status

• Copper and fiber duplex mode

• Copper port speed

• Hardware switch setting

Also, you can use SNMP to enter network commands that do the following:

• Enable/disable Auto-Negotiation on copper

• Force 10Mb/s or 100Mb/s on copper

• Force full duplex or half duplex on copper

• Force full duplex or half duplex on fiber

• Enable/disable Far-End Fault on fiber

• Enable/disable Link Pass Through

The physical characteristics must meet or exceed the IEEE 802.3™ specifications.

If the PWR LED is not lit, follow these steps:

• Check if the power cord is properly installed in the media converter and at the external power source.

• Verify that the external power source is active.

If the LED is still not lit, you may need to contact technical support.

If the TLNK LED is not lit, it indicates a problem with the copper connection. Check the copper cables for proper connection and pin assignment. If the problem persists, you may need to contact technical support. If the TLNK LED is lit, proceed to the next troubleshooting step.

If the FLNK LED is not lit, it indicates a problem with the fiber connection. Perform the following checks:

• 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 the problem persists, you may need to contact technical support. If the FLNK LED is lit, proceed to the next troubleshooting step.

The TPSD LED indicates the speed of the copper connection.

If the TPSD 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 the TPSD 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 troubleshooting does not resolve the speed issue, contact technical support.
