FCC NOTICE
This device complies with Part 15 of the FCC rules. Operation is
subject to the following two conditions: (1) this device may not cause
harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation.
NOTE :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 uses, generates, and can
radiate radio frequency energy and if not installed in accordance with
the operator’s manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is
likely to cause interference in which case the user will be required to
correct the interference at his own expense.
WARNING : Changes or modifications made to this device which are
not expressly approved by the party responsible for compliance could
void the user’s authority to operate the equipment.
DOC NOTICE
This digital apparatus does not exceed the Class A limits for radio
noise emissions from digital apparatus set out in the Radio
Interference Regulations of the Canadian Department of
Communications.
Le présent appareil numérique n’émet pas de bruits radioélectriques
dépassant les limites applicables aux appareils numériques de la class
A prescrites dans le Règlement sur le brouillage radioélectrique édicté
par le ministère des Communications du Canada.

SAFETY INFORMATION
CLASS 1 LASER TRANSCEIVERS
Class 1 Laser Products
The FDCMIM-34 and FDCMIM-38 connectors use Class 1 Laser
transceivers. Read the following safety information before installing
or operating the FDCMIM-34 or FDCMIM-38.
The Class 1 laser transceivers use an optical feedback loop to
maintain Class 1 operation limits. This control loop eliminates the
need for maintenance checks or adjustments.The output is factory set,
and does not allow any user adjustment. Class 1 Laser transceivers
comply with the following safety standards:
• 21 CFR 1040.10 and 1040.11 U.S. Department of Health and
Human Services (FDA).
• IEC Publication 825 (International Electrotechnical
Commission).
• CENELEC EN 60825 (European Committee for
Electrotechnical Standardization).
When operating within their performance limitations, laser
transceiver output meets the Class 1 accessible emission limit of all
three standards. Class 1 levels of laser radiation are not considered
hazardous.

Laser Radiation and Connectors
When the connector is in place, all laser radiation remains within the
fiber.The maximum amount of radiant power exiting the fiber (under
normal conditions) is -12.6dBm or 55x10
-6
watts.
Removing the optical connector from the transceiver allows laser
radiation to emit directly from the optical port.The maximum
radiance from the optical port (under worst case conditions) is 0.8 W

.
WARNING : Do not use optical instruments to view the laser output.
The use of optical instruments to view laser output increases eye
hazard.When viewing the output optical port, you must remove power
from the network adapter.

CHAPTER 1
INTRODUCTION
The FDCMIM-04/08/24/28/34/38/44/48 are components of a modular
dual attached concentrator.These components attach to an FDDI dual
ring through the Cabletron Systems FDMMIM, FDMMIM-04,
FDMMIM-24, or FDMMIM-30.
Note: Throughout this manual, unless otherwise noted, the term
FDCMIM refers to the FDCMIM-04/08/24/28/34/38/44/48.
FDCMIMs reside in a Multi Media Access Center (MMAC), and you
can use them either with or without an FDMMIM, since you can form
a stand-alone FDDI network using one or more FDCMIMs.
The FDCMIM-X4s have four and the FDCMIM-X8s have eight master
ports (where X varies, depending on the cable/transmitter type) that
accept different connectors. Chapter 4,
Specifications , lists the
operating specifications for the different available FDCMIM cable and
transmitter types.
1.1 USING THIS MANUAL
This manual explains how to install FDCMIM concentrator modules.
The following summarizes the chapter organization.
Chapter 1, Introduction , describes the FDCMIM and its features.
Chapter 2, Configuration and Installation , includes installation
requirements, and detailed instructions for installing your FDCMIM
into an MMAC hub as a stand-alone concentrator.
Chapter 3, Using LANVIEW
®
, describes the purpose of each
FDCMIM LANVIEW LED.
Chapter 4, Specifications , provides operating specifications for each
FDCMIM cable/transmitter type.

1.2 OVERVIEW
The FDCMIM is a concentrator module that resides in an MMAC
network hub containing a Flexible Network Bus (FNB).The FDCMIM
acts as a modular component in a Dual Attached Concentrator.
FDCMIMs (and their attached stations) gain access to an FDDI dual
ring network through an FDMMIM, FDMMIM-04, FDMMIM-24, or
FDMMIM-30 the Cabletron Systems X3T9.5 compliant Dual Attached
Concentrator and Ethernet to FDDI Bridge Media Interface Modules.
The FDCMIM connects to the FDMMIM through the FDDI portion of
the MMAC Flexible Network Bus.

Media Interface Modules
By using an FDMMIM, FDMMIM-04, FDMMIM-24, or FDMMIM-30
you can manage adjacent FDCMIMs through FDMMIM Local
Management, the out-of-band management facility resident on the
FDMMIM and FDMMIM-04 modules.You can also manage FDCMIMs
with Cabletron Systems SNMP management tools such as
SPECTRUM
®
or Remote LANVIEW/Windows
®
.
FDCMIMs also provide the flexibility of forming a single ring stand-
alone FDDI concentrator. Since FDCMIMs connect through the
MMAC backplane through an isolated FDDI bus, you can link several
modules, and their subsequent stations, together without the need for
a bridge or repeater.
