Notice
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
The FPIM-05 and FPIM-07 are Class 1 Laser Products
Notice
CLASS 1
LASER PRODUCT
The FPIM-05 and FPIM-07 use Class 1 Laser transceivers. Read the
following safety information before installing or operating these
adapters.
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.

Notice
Safety Information
CLASS 1 LASER TRANSCEIVERS
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 -12.6 dBm or 55 x 10
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 cm
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, power must
be removed from the network adapter.

Introduction
The 9F206-02 (as shown in Figure 1-1) is an FDDI repeater module for the
MMAC-Plus that provides external access to the Flexible Network Bus (FNB)
backplane via two sets of FDDI-compliant A/B ports. This allows the FNB to
traverse multiple MMAC-Plus systems, or connect to any ASNI FDDI-compliant
device in an FDDI network. The 9F206-02 module attaches to both FDDI networks
on the FNB backplane, FNB-1 and FNB-2, but can be controlled separately with
DIP switches or local management tools. The 9F206-02 can also be used to
Dual-Home an MMAC-Plus chassis to multiple points in the network. Using
standard FDDI chip-set technology, the 9F206-02 module completely re-times and
regenerates data signals for error free transmission and guaranteed
interoperability.

Features
System Management
The 9F206-02 requires minimal management. It can be completely managed and
controlled through the SMB-1. The management features include the following:
• Front Panel Port Status
• Insertion/bypass Control (FDDI-1 and FDDI-2) and Status
• FPIM Identification (Front Panel)
Connectivity
The 9F206-02 uses FDDI Port Interface Modules (FPIMs) to provide several media
options for the front panel (FNB-1 and FNB-2) interfaces. These FPIMs are
available in various media types including the following:
• Multimode Fiber Optic (FDDI MIC)
• Single Mode Fiber Optic (FDDI MIC)
• Unshielded Twisted Pair (RJ-45)
• Shielded Twisted Pair (RJ-45)
• Multimode Fiber Optic (SC)
• Singlemode Fiber Optic (SC)

Introduction
LANVIEW LEDs
The 9F206-02 uses LANVIEW: the Cabletron Systems built-in visual diagnostic
and status monitoring system for at-a-glance diagnosis of the network. With
LANVIEW LEDs, you can quickly identify the device, port, and physical layer
status.
Hot Swapping
The 9F206-02 can be installed or removed from the chassis while the MMAC-Plus
is powered up without affecting the operation of the rest of the system.
