*Typical maximum cable distance. Actual distance is dependent upon the

physical characteristics of the network. (TX) = transmit (RX) = receive

**SBFTF1029-120and -121are intended to be installed in the same network where one is the local converter and the other is the remote converter.

***SBFTF1029-122and -123are intended to be installed in the same network where one is the local converter and the other is the remote converter.

Installation -- Continued

Set the Dip Switches

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

“SW1” switches 1 - 6

Dip switches 1, 2, and 3 apply only to twisted-pair copper port 1 (TP1).

Dip switch 4 applies to fiber port 1 (F1).

Dip switch 5 applies to all twisted-pair copper ports (TP1, TP2, TP3, TP4, TP5).

Dip switch 6 is not in use.

“Config. Switches” 1 - 4

Dip switches 1, 2, 3, and 4 apply only to twisted-pair copper port 2 (TP2).

NOTE: Switches 1, 2, and 3 apply only to twisted-pair copper port 1 (TP1).

The chassis version of the media converter is CBFTF10xx-12x. For more information, see the CBFTF10xx-12x user’s guide on-line at: www.transition.com.

Installation

Copper and Fiber Ports

The figure below illustrates the locations of the five (5) twisted-pair copper ports and the one (1) fiber port.

1. Twisted-Pair Auto-Negotiation

Up (Enabled) - The media converter “advertises” ALL rate and mode capabilities to the network:

• 100Mb/s full-duplex	• 100Mb/s half-duplex,
• 10Mb/s full-duplex	• 10Mb/s half-duplex.

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

2. Twisted-Pair Rate

Up (100Base-TX)- Sets the twisted-pair rate to 100Base-TX.

Down (10Base-T)- Sets the twisted-pair rate to 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):- The twisted-pair cable distances are constrained by the 512-Bit Rule (see page 9).
