SBFTF1010-130
10/100 Fault-Tolerant Redundant Link
Protector
• 10/100 Base-T(x) to 10/100 Base-T(x)
• Ethernet/Fast Ethernet
The SBFTF1010-130 is a fault-tolerant redundant link protector provides redundant
paths for fast Ethernet devices. It has three ports: main, primary, and backup. 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.

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, the
user 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., 10 Mbps,
half-duplex). Disabling this feature gives the user the ability to force the connection
to the desired speed and duplex mode.
Data Transfer rate (selectable)
10Base-T data transfer rate: 10 Mbps baseband Ethernet.
100Base-TX data transfer rate: 100 Mbps baseband Ethernet.
Product features -- continued
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 SBFTF-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.
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
CAUTION: Do Not install the SBFTF1010-130 fault-tolerant redundant link protector
in location where it might be exposed to wetness. Failure to observe this caution could
result in damage to the device.
Jumper (shunt)
The 3-pin header located on the inner surface of the board is used to select
“redundancy.” See photo below. Redundancy Mode automatically switches data
transfer responsibilities to the seconday port if the primary port fails.

10Mb/s half duplex.
When auto-negotiation is disabled (switch #1 DOWN), the bridging
media converter does not advertise rate and mode capabilities to the
network.

Installation --continued
Installing the twisted-pair copper cable
1. Locate or build an IEEE 802.3 compliant 10Base-T or 100Base-TX cables, with
male RJ-45 connectors installed onto both ends.
2. Connect the RJ-45 connector at one end of the cable to the RJ-45 port on the
bridging media converter as shown below.
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.) as shown below.
Note: The MDI (straight-through) cable or the MDI-X (crossover) cable connection is
configured automatically, according to network conditions.

Connecting power to the bridging media converter
AC/DC:
1. Connect the barrel connector of the adapter to the power port of the bridging
media converter (located on the back of the converter shown below).
2. Connect the power adapter plug into AC power: if all the configuration switches
are in the UP position, the port LEDs will flicker during the initialization
process and then go OFF.
Note: The power-on LED will be lit (ON).

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.
