TRANSITION NETWORKS CBFTF1014-105 (01) PDF DOCUMENT

The TRANSITION NETWORKS CBFTF1014-105 Slide-in-Module Media Converter has the following features:

• Extend network distance up to 120 km with an SFP module

• Convert 10/100 on copper to straight 100 on fiber

• Half or Full-Duplex on both ports

• Fully manageable

• Auto-Negotiation and AutoCross™

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

• Automatic Link Restoration

• Field Upgradeable Firmware

• Can be used with any Point System™ Chassis

• Bridging media converters provide conversion and integration solutions for half- and full-duplex environments

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. The functions for each switch position 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 a 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: 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 settings.

To install the TRANSITION NETWORKS CBFTF1014-105 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 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 CBFTF1014-105 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 TRANSITION NETWORKS CBFTF1014-105 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 operation of the TRANSITION NETWORKS CBFTF1014-105 media converter.

• 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 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, 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 TRANSITION NETWORKS CBFTF1014-105 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.

You may want to disable Auto-Negotiation in a scenario where the media converter is linked to a non-negotiating device. 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.

Using SNMP, you can monitor 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 for 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

• Pins 1&2 and 3&6 are the two active pairs in an Ethernet network.

• Use only dedicated wire pairs for the active pins (e.g., blue/white & white/blue, orange/white & white/orange, etc.)

• Do not use flat or silver satin wire.

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

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

• Does the external power source active?

If these steps do not resolve the issue, you will need to contact technical support.

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

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

If the issue persists, contact technical support.

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

• 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 issue persists, contact technical support.

The TPSD LED indicates the speed of the copper connection.

• If the TPSD LED is OFF: The media converter has selected 10Mb/s operation. If this speed is not correct, disconnect and reconnect the twisted pair cable to restart the initialization process. If the issue persists after checking the copper cables for proper connection, contact technical support.

• If the TPSD LED is ON: The media converter has selected 100Mb/s operation. If this speed is not correct, disconnect and reconnect the twisted pair cable to restart the initialization process. If the issue persists, contact technical support.
