Transition Networks C/A-CF-02(SM), C/A-CF-02 User Manual

The TRANSITION Networks ATM (Asynchronous Transfer Mode) C/A-CF-02

series Slide-In-Module media converters, designed to be installed in the
TRANSITION Networks Media Conversion Center, E-MCC-1600, connect

twisted-

pair copper cable to multimode OR to singlemode fiber optic cable.
NOTE: Effective cable distances are

determined by ambient RF noise and
by signal loss in the cable. The fiber
connection, with low signal loss and
high resistance to radio frequency
noise, allows extended distances
between ATM devices. Twisted-pair
runs are best kept as short as possible
to preserve signal integrity.

C/A-CF-02

The ATM media converters provide
network connection using an RJ-45
twisted-pair ATM connector and a
set of RX (receive) and TX (transmit)

SC connector to multimode fiber-
optic cable.

C/A-CF-02(SM)

The ATM media converters provide
network connection using an RJ-45
twisted-pair ATM connector and a
set of RX (receive) and TX (transmit)

SC connector to singlemode fiber-
optic cable.

USER’S GUIDE

CAUTION: RJ connectors are NOT INTENDED FOR CONNECTION TO THE
PUBLIC TELEPHONE NETWORK. Failure to observe this caution could result in
damage to the public telephone network.

The two active pairs in an
ATM network are pins 1 & 2
and pins 7 & 8. Use only
dedicated wire pairs (such as
blue/white & white/blue,
orange/white & white/orange)
for the active pins.

1. Is the power LED on the media converter illuminated?

NO

• Is the Slide-In-Module properly connected to the Media Conversion Center
chasis backplane?

• Is the Power Supply Module properly connected both to the Media Conversion
Center chasis backplane and to the AC outlet?

• Contact Technical Support at [phone]/ (800) LAN-WANS.

YES

• Proceed to step 2.

2. Is the Copper Activity LED illuminated?

NO

• Check UTP cables for proper connection and pin assignment. (See above.)

• Contact Technical Support at [phone]/ (800) LAN-WANS.

YES

• Proceed to step 3.

3. Is the Fiber Activity LED illuminated?

NO

• Check fiber cables for proper connection.

• Verify that TX and RX cables on media converter are connected to RX and TX
ports, respectively, on the other 100BASE-FX device.

• Refer to Tech Tips available at: http://www.transition.com

• Contact Technical Support at [phone]/ (800) LAN-WANS.

YES

• KEEP twisted-pair RUNS AS SHORT AS POSSIBLE.

• Install no more than two (2) media converters in series.

Be certain that the twisted-pair cable is configured correctly (straight through
or crossover) for site. Cable connections between an ATM switch and the

media converter must be configured as straight through. Cable connections
between the media converter and a NIC must be configured as crossover.

The physical characteristics of the media cable must meet or exceed the
specifications: ATM UNI 3.1 #AF-PHY-0015
Maximum number of media converters in series: 2

Installing Slide-In-Module(s)

CAUTION: Wear a grounding device and observe electrostatic discharge precautions
when installing Media Converter Slide-in-Module(s) in the 16-Slot Media Conversion
Center. Failure to observe this caution could result in damage to, and subsequent

NOTE: Slide-in-Modules can be installed in any installation slot, in any order.
To install the Media Converter Slide-in-Module in the E-MCC-1600 chassis:

1. 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.

2. 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 seated firmly against the
backplane.

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