*Typical maximum cable distance. Actual distance is dependent upon the physical characteristics of the network. (TX) = transmit (RX) = receive

**CBFTF1029-100/101 pair or -102/103 pair should be installed in the same network where one as local and the other is the remote converter.

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).

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.

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).

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, and

•10Mb/s half-duplex.

UP

Twisted-pair Auto-Negotiation ON

DOWN

Twisted-pair Auto-Negotiation OFF

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.

UP

AutoCross Enable

DOWN

AutoCross Disable

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

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.
