The TRANSITION Networks 3270 Twisted Pair/Coax (Copper) to Fiber
C/B-CF-01series media converters, designed to be installed in the E-MCC-1600
chassis and to support all IBM®3270 compliant devices, extends the signal
distance of a 317x or 327x Cluster Controller to terminal links.

C/B-CF-01 series media converters allow twisted-pair copper network
extension distances up to 1524 meters (762 meters each connection on two
media converters) OR coax copper network extension distances up to 614
meters (307 meters each connection on two media converters) AND fiber
network extension distances up to 2 kilometers on multimode fiber and up
to 8 kilometers on singlemode fiber.*

Installation NOTES

To install the C/B-CF-01 series media converter:

1. Install the C/B-CF-01 in the E-MCC-1600 chassis.

NOTE: Media Converter Slide-in-Modules can be installed in any
installation slot, in any order.

• Remove Media Converter Slide-in-Module protective plate
from selected installation slot by removing two screws that
secure plate to front of E-MCC-1600. Retain one installation
screw.

• Carefully slide Media Converter Slide-in-Module into
installation slot, aligning Media Converter Slide-in-Module
with installation guides.

NOTE: Ensure that the Media Converter Slide-in-Module is firmly
seated against the backplane.

• Secure Slide-in-Module by installing retained installation
screw.

2. Connect host signal to C/B-CF-01 media converter.

NOTE: Set the configuration switch (located on the side of the media
converter) according to site requirements, using the following:

Switch 1 NOT USED
Switch 2 UP = Twisted Pair

DOWN = Coax

Twisted-pair:

• Locate or build twisted-pair cables (See specifications, page 7)
with male RJ-45 plug connectors at both cable ends.

NOTE: Install TRANSITION Networks balun part number: B-4554
between RJ-45 cable and coax connector.

• Install balun at host coax connector.

• Connect male RJ-45 plug connector at one end of twisted pair
cable to balun on host coax connector.

• Connect male RJ-45 plug connector at other end of cable to
female RJ-45 connector on B-CF-01 media converter.

Coax:

• Locate or build coaxial RG-62 cables (See specifications, page

7) with male BNC connectors at both ends.
