*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.

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 6-position DIP switch (SW2) is located on the edge of the PCB. Use a small flat blade screwdriver to set the switches according to the following functions:

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

• Software Mode: The media converter mode is determined by the most-recently saved on-board settings. (Place jumper over ‘S’ and middle pin).

• Hardware Mode: The media converter mode is determined by the 6-position DIP switch settings. (Place jumper over ‘H’ and middle pin).

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.

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 an IEEE 802.3 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 802.3 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 media converter operation in the network.

AutoCross™

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.

Link Pass-Through (LPT)

This 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, 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 condition 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 the 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 will broadcast its speed (10 Mb/s or 100 Mb/s) and duplex capabilities (full or half) to other devices and negotiate the best mode. This allows for quick and easy installation. Auto-Negotiation can be disabled to force a connection to the best mode of operation, especially when linking to a non-negotiating device.

Parallel Detection

This is the method used when an auto-negotiating port detects a link partner that is in forced mode. Parallel Detection can be set to IEEE Standard half duplex, or 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 detecting a forced link partner should drop to the detected speed (10Mbps or 100Mbps) and default to HALF DUPLEX. This media converter allows bypassing the IEEE method by setting the parallel detection default mode to half or full duplex via DIP switch 3.

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

• 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

You can also use SNMP to enter network commands to perform the following actions:

• 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

CAUTION: Copper based media ports, e.g., Twisted Pair (TP) Ethernet, USB, RS232, RS422, RS485, DS1, DS3, Video Coax, etc., are intended to be connected to intrabuilding (inside plant) link segments that are not subject to lightening transients or power faults. Copper based media ports are NOT to be connected to inter-building (outside plant) link segments that are subject to lightening transients or power faults. Failure to observe this caution could result in damage to equipment.

CAUTION: RJ connectors are NOT INTENDED FOR CONNECTION TO THE PUBLIC TELEPHONE NETWORK. Failure to observe this caution could result in damage to the public telephone network.

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 (Off = 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 (On = 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.
