Compliance Information

UL Listed
C-UL Listed (Canada)
CISPR/EN55022 Class A

FCC Regulations

This equipment has been tested and found to comply with the limits for a class A digital device, pursuant
o part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment. This equipment generates,
uses, and can radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications. Operation of this equipment
in a residential area is likely to cause harmful interference, in which case the user will be required to
correct the interference at the user’s own expense.

Canadian Regulations

This digital apparatus does not exceed the Class A limits for radio noise for digital apparatus set out on the
radio interference regulations of the Canadian Department of Communications.

European Regulations

Warning

This is a Class A product. In a domestic environment this product may cause radio interference in which
case the user may be required to take adequate measures.

The TRANSITION Networks ARCNET®RJ-11 Copper/Fiber Media Converter (series
C/AR-CF-01), designed to be installed in the TRANSITION Networks Media Conversion
Center, E-MCC-1600, extends the signal distance of an ARCNET

®

segment or node
link up to 2 kilometers over fiber*, up to 100 meters over twisted-pair copper in a star topology,
and up to 120 meters over twisted-pair copper in a bus topology. A switch on the media
converter allows the media converter to terminate the link or node signal.

STATUS LEDS

Power Steady green LED indicates

connection to external AC
power.

UTP/STP Blinking green LED

indicates network traffic on unshielded or shielded twisted-pair link.

Fiber Blinking green LED indicates network traffic on fiber link.
*Consider carefully the network constraints imposed by the maximum latency

response time of installed equipment. Some equipment cannot handle the extended
response time that 2 kilometers of fiber introduces.

Installation NOTES

Install Slide-In-Module Media Converter

To install the Media Converter Slide-in-Module in the E-MCC-1600 chassis:

• 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.

Install Twisted-pair Copper

STAR TOPOLOGY

• MAXIMUM twisted-pair segment to active hub is 100 meters (300
feet); minimum does not apply.

BUS TOPOLOGY

• Devices attached to twisted-pair bus must be located AT LEAST six
(6) feet apart.

• MAXIMUM twisted-pair bus length is 120 meters (400 feet).

• Device(s) attached to EACH END of bus must be terminated. NOTE:
If the media converter is installed at one end of the bus, use the
configuration switch to terminate the media converter.

CONFIGURATION SWITCH

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

Switch 1 NOT USED
Switch 2 UP = OFF Media converter TRANSFERS signal

DOWN = ON Media converter TERMINATES signal.

Install Fiber

Connect one end of first fiber cable to C/AR-CF-01 media converter TX
connector. Connect other end of that fiber cable to second C/AR-CF-01 media
converter RX connector. Connect one end of second fiber cable to C/AR-CF-01
media converter RX connector. Connect other end of that fiber cable to C/AR­CF-01 media converter TX connector.

Power Slide-In-Module Media Converter

Locate correct power supply adapter for site installation. Connect media
converter power connector at end of power supply adapter cord to C/AR-CF-01
media converter power receptacle. Connect 2-prong or 3-prong external power
connector on other end of power supply adapter cord to external AC power.
