Installation

Set the Configuration Switches

The configuration switches are located on the side of the media converter. Use a small, flat-blade screwdriver or a similar device to set each switch.

NOTE:

•Switches 1, 2, 3, and 5 apply to the copper port.

•Switch 4 applies to the fiber port.

•Switch 6 applies to the media converter.

1.Twisted-Pair Auto-Negotiation

	UP (Enabled) - The media converter “advertises”	1
		UP
	ALL rate and mode capabilities to the network:
		Twisted-pair Auto-Negotiation ON
	• 100Mb/s full-duplex,
	• 100Mb/s half-duplex,	DOWN
	• 10Mb/s full-duplex, and	Twisted-pair Auto-Negotiation OFF
	• 10Mb/s half-duplex.

DOWN (Disabled) - The bridging media converter does not “advertise” the rate and mode capabilities to the network. Switch #2 and switch #3 are then used to set the twisted-pair rate and mode.

2. Twisted-Pair Rate

2

UP - Sets the twisted-pair rate to 100Base-TX.	UP
DOWN - Sets the twisted-pair rate to 10Base-T.	Twisted-pair 100Base-TX
	DOWN
	Twisted-pair 10Base-T

3. Twisted-Pair Mode

UP (Full-Duplex):

The twisted-pair cable distances are constrained by the cable requirements (see pages 1 and 2).

DOWN (Half-Duplex):

At the 100Base-TX rate, the twisted-pair cable distances are constrained by the 512-Bit Rule (see page 9).

At the 10Base-T rate, the twisted-pair cable distances are constrained by the 5-Segment Rule (see page 10).

UP

Twisted-pair Full-Duplex

DOWN

4. Fiber Mode

UP (Full-Duplex) - The fiber cable distances are constrained by the cable requirements (see pages 1 and 2).

DOWN (Half-Duplex) - The fiber cable distances are constrained by the 512-Bit Rule (see page 10).

5. AutoCross

UP (Enable) - The media converter connects automatically to either straight-through or crossover twisted-pair copper cable.

DOWN (Disable) - Either straight-through or crossover twisted-pair copper cable must be installed, according to the site requirements.

	6. Link Pass-Through	6
	UP (Enable) - When Link Pass-Through is enabled, a
		UP
	fault on one side of the media converter stops the
		Link Pass-Through Enable
	signal and data transmission on the other side.

DOWN (Disable) - When Link Pass-Through is

DOWN

disabled, a fault on one side of the media converter does not stop the signal and data transmission on the other side.

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.
