*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. CAUTION: Wear a grounding device and observe electrostatic discharge precautions when setting the 6-position DIP switch. Failure to observe this caution could result in damage to the media converter.

The settings are as follows:

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.

(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. Use small needlenosed pliers or a similar tool to set the jumper, which is labeled “H” for hardware and “S” for software.

• 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 CBFTF10xx-105 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.

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 (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 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.

Use the status LEDs to 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.

The AutoCross feature detects and configures the twisted-pair copper port on the media converter 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.

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 the TX (transmit) signal on the other port, 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 has a link up but is being forced down will blink on and off every 2 seconds.

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. This allows for quick and easy installation because the optimal link is established automatically with no user intervention required.

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 converter allows bypassing the IEEE method by setting the parallel detection default mode to half or full duplex via DIP switch 3.

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