CBFTF1010-130 10/100 Fault-Tolerant Redundant

Link Protector

• 10/100 Base-T(x) to 10/100 Base-T(x)
Ethernet/Fast Ethernet

• Three RJ-45 Ports

The CBFTF1010-130 is a fault-tolerant redundant link protector that provides redundant
paths for fast Ethernet devices. It has three RJ-45 ports. As a redundant link protector,
typically, the main port connects to a critical 10/100 fast Ethernet device. The primary
port and the backup port connect to two different switch ports or two different ports on
separate switches. When the unit powers up, it checks the primary port for a link signal; if
the signal is present, the main and primary ports connect and the signal from the backup
port is then disabled. Any device connected to the backup port will not detect a signal at
this time. However, if the device does not detect a signal on the primary port, then the
main port and backup port connect.

Optional functionality controlled via DIP switches enable changing the transceiver from
fault-tolerant mode to switch mode.

Product Features

Front panel

The CBFTF1010-130 bridging media converter has three RJ-45 10/100Base-TX
ports. See illustration below

Auto-Negotiation (selectable)

The Auto-Negotiation feature automatically configures the bridging media
converter to achieve the best possible mode of operation over a link. The bridging
media converter broadcasts its speed (10 Mbps or 100 Mbps) 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 required.

In a scenario where the media converter is linked to a non-negotiating device,
disable Auto-Negotiation. In this instance, the mode of operation will drop to the
least common denominator between the two devices (e.g., 10 Mbps, half-duplex).
Disabling this feature allows forcing the connection to the desired speed and duplex
mode.

Data transfer rate (selectable)

10Base-T data transfer rate: 10 Mbps Ethernet.

100Base-TX data transfer rate: 100 Mbps Ethernet.

Full-Duplex network (selectable)

In a full-duplex network, maximum cable lengths are determined by the type of
cables used. The 512-Bit Rule does not apply in a full-duplex network.

Half-Duplex network (selectable) (512-Bit Rule)

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., 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.

AutoCross™

When the AutoCross feature is activated, it allows either straight-through MDI or
crossover MDI-X cables to be used when connecting to 10Base-T or 100Base-TX
devices. AutoCross determines the characteristics of the connection and
automatically configures the unit to link up, regardless if the cable configuration is
MDI or MDI-X. This feature is ON permanently.

Installation

Note: Wear a grounding strap when removing the circuit board from its anti-static

bag.

Jumpers

The two, 3-pin headers located on the inner surface of the board are used to select
“hardware” and “software” modes, and “redundancy.” See photo below.

• Hardware Mode: DIP switches control the function of the board. You can view
status only via the Web or Focal Point interface.

• Software Mode: Software controls the function of the board. The DIP switches do
not function in software mode.

• Redundancy: automatically switches data transfer responsibilities to the seconday
port if the primary port fails.

Redundancy (selectable)

With redundancy enable and the primary port fails, the converter automatically
switches data transfer responsibilities to the backup port without disrupting
network traffic. After the primary port's failure is resolved, the converter
automatically switches data transfer responsibilities back to the primary port.

Parallel detection

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 does not provide the ability to detect half
versus full duplex mode

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 xBFTF-130 allows bypassing the IEEE method by setting the parallel
detection default mode to half or full duplex via DIP switch 3 or through the
duplex setting via WEB and Focal Point interfaces.

When Auto-Negotiation is enabled (switch #1 UP), the bridging media
converter advertises all rate and mode capabilities to the network:
100Mb/s full duplex, 100Mb/s half-duplex, 10Mb/s full duplex, and
10Mb/s half duplex.

Note: Switch “2” does not function when switch “#1” is in the UP position (Auto-

Negotiation enabled).

When auto-negotiation is disabled (switch #1 DOWN), the bridging
media converter does not advertise rate and mode capabilities to the
network.

100Base-TX data transfer rate (switch #2 UP), 100 Mbps fast Ethernet.

10Base-TX data transfer rate (switch #2 DOWN), 10 Mbps fast Ethernet.

Note: See the diagrams below and use a very small flatblade screwdriver or similar

tool to set the DIP switch.

Full duplex (switch #3 UP with auto-negotiation disabled ). Also when
Parallel detection occurs (auto-negotiation enabled only), the device
will be forced to full duplex.

Half duplex (switch #3 DOWN with auto-negotiation disabled ). Also
when Parallel detection occurs (auto-negotiation enabled only), the
device will be forced to half duplex.

Redundancy enabled switch #4 UP (with J2 shunt in the “R” position)

Redundancy enabled switch #4 DOWN (with J2 shunt in the “R”
position). See notes below

Note: With redundancy turned OFF ), the primary and secondary port LEDs will turn

OFF; therefore, returning these ports to normal functionality.

Note: The functionality for each switch setting applies to all ports simultaneously.
Note: With the shunt removed from header J2, the switch is set to redundant mode.

Cable Specifications

Copper cable (10Base-T/100Base-TX)

Ensure that the correct cable type is installed to support the highest speed and mode of
operation. Though category 3 cable is adequate for a 10Base-T installation, category 5
cable is recommended, since category 3 cable DOES NOT support 100Base-TX.

Category 3: (minimum requirement for 10 Mbps operation)

Gauge: 24 to 22 AWG
Attenuation: 11.5 dB/100m @ 5-10 MHz
Maximum cable distance: 100 meters

Category 5: (minimum requirement for 100 Mbps operation)

Gauge: 24 to 22 AWG
Attenuation: 22.0 dB/100m @ 100 MHz
Maximum cable distance: 100 meters

• Straight-through (MDI) or crossover (MDI-X) cable may be used.

• Shielded (STP) or unshielded (UTP) twisted-pair cable may be used.

• 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.

10Base-T and the Ethernet collision domain:

• Refer to the 5-Segment Rule before installing half-duplex 10Base-T

cable.

• Installing full-duplex twisted-pair cable avoids collision domain
considerations—maximum distance 100 meters.

100Base-TX and the Fast Ethernet collision domain:

• Refer to the 512-Bit Rule before installing half-duplex 100Base-TX cable.

• Installing full-duplex twisted-pair cable avoids collision domain
considerations—maximum distance 100 meters.

Note: A Fast Ethernet collision domain can have only “1” Class “I” repeater or “2”

Class “II” repeaters.
