Transition Networks C/TR-CF-01(SM), C/TR-CF-01 User Manual
Both media converters function at 4Mb/s or 16Mb/s in half-duplex mode or,
when connected to devices capable of full-duplex connectivity, in full-duplex
mode for up to 32Mb/s total throughput.
NOTE: The fiber interface LEDs are NOT illuminated until the twisted-pair side
has been initialized and asserts a phantom voltage to the fiber. (See a description
of the activity of the Token Ring twisted-pair to fiber signal in “Media Converters
in the Network” on page 4.)

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
to 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.

TOKEN RING CABLE SPECIFICATIONS
INSTALLATION
Twisted-pair Cable
• Category 5 twisted-pair cable is recommended; Category 3 and 4 are
supported at reduced cable lengths.
Fiber Extension Cable
• Be certain that the fiber extension cable is correct for distances required at
the site installation.
CAUTION: Wear a grounding device and observe electrostatic
discharge precautions when installing Media Converter Slide-inModule(s) in the 16-Slot Media Conversion Center. Failure to observe
this caution could result in damage to, and subsequent failure of, the
Media Converter Slide-in-Module(s).
Set the switches accordng to the chart on page 3 BEFORE installing
slide-in-module media converter in the media conversion center; if
necessary, refer to the chart on pages 4-5 to determine network
considerations.
Be certain that the media converter 1: mode, 2: active/passive state,
3: IEEE 802.5j compliance/non-compliance, and 4: twisted-pair cable
configuration (straight through/RO or crossover/RI) are set correctly for
the site installation.
The physical characteristics of the media cable must meet or exceed IEEE 802.5
and 802.5j specifications.

Setting Configuration Switch
NOTE: Media Converter 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 firmly
seated against the backplane.
3. Secure Slide-in-Module by installing retained installation screw.
