Installation -- Continued
Connect the Twisted-Pair Copper Cable
Ensure that the correct cable type is installed to support the highest speed and
mode of operation to be selected.
Although Category 3 cable is adequate for the 10Base-T installation, Category 5
cable is strongly recommended, since Category 3 cable can not be used for
100Base-TX installation.
10Base-T / Ethernet collision domain
• If half-duplex cable is used, refer to the 5-Segment Rule (page 10) before
installing the 10Base-T twisted-pair copper cable.
• If full-duplex cable is used, the 5-Segment Rule does not apply. The cable
lengths are constrained by the cable requirements (see pages 1 and 2).
100Base-TX / fast Ethernet collision domain
• If half-duplex cable is used, refer to the 512-Bit Rule (page 10) before
installing the 100Base-TX twisted-pair copper cable.
• If full-duplex cable is used, the 512-Bit Rule does not apply. The cable
lengths are constrained by the cable requirements (see pages 1 and 2).
NOTE: A fast Ethernet collision domain can have one one class I repeater or
two class II repeaters.
Install the Twisted-Pair Copper Cable
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 IEEE 803.2™ compliant 10Base-T or 100Base-TX cables,
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 SBFTF10xx-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.).

Connect the Fiber Cable
100Base-FX / fast Ethernet collision domain
• If half-duplex mode is used, refer to the 512-Bit Rule (page 9) before
installing the 100Base-FX fiber cable.
• If full-duplex mode is used, the 512-Bit Rule does not apply. The cable
lengths are constrained by the cable requirements (see pages 1 and 2).
Install the Fiber Cable
1. Locate or build 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 SBFTF10xx-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.

Power the Media Converter
NOTE: The external power supply provided with this product is UL listed by
the power supply’s manufacturer.
AC
1. Connect the barrel connector on the power adapter to the media
converter’s power port (located on the back of the media converter).
2. Connect the power adapter plug to AC power.
3. Verify that the media converter is powered by observing the illuminated
LED power indicator light.
DC
Consult the user’s guide for the Transition Networks SPS1872-xx DC external
power supply for powering the media converter.
