Safety Information  
CLASS 1 LASER TRANSCEIVERS  
The FPIM-05 and FPIM-07 are Class 1 Laser Products  
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.

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.  
-6  
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  
-2

conditions) is 0.8 W cm or 8 x 10 W m sr-1.  
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  
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.

Installing the MicroLAN Module  
This module uses FPIMs for the front panel connections. They are not shipped  
with the module and must be purchased separately. For more information on  
FPIMs see Appendix A.  
Unpacking the Module  
1. Carefully remove the module from the shipping box. (Save the box and  
packing materials in the event the module must be reshipped.)  
2. Remove the module from the plastic bag. Observe all precautions to prevent  
damage from Electrostatic Discharge (ESD).  
3. Carefully examine the module, checking for damage. If any damage exists,  
DO NOT install the module. Contact Cabletron Systems Technical Support  
immediately.  
Installing an FPIM  
FPIMs are required for the 9F206-02 and are ordered and shipped separately. To  
install an FPIM, follow the procedure below:  
1. Remove the module if it is installed in the MMAC-Plus chassis.  
2. Remove the blank front cover over the FPIM slot.  
3. Install the FPIM as shown in Figure 2-1. Ensure that the rear connector is  
seated firmly before tightening the two mounting screws.

Installing the MicroLAN Module  
Installing the Module into the MMAC-Plus Chassis  
MMAC-Plus MicroLAN Modules can be installed in any of the 14 slots that are  
available. To install, follow the steps below:  
1. Switch off the power supplies and remove all power from the MMAC-Plus  
chassis.  
2. Remove the blank panels, covering the slots that the module is being  
mounted in. All other slots must be covered, if modules are not being  
installed, to ensure proper airflow and cooling.  
3. Attach one end of the ESD wrist strap packaged with the MMAC-Plus chassis  
to your wrist. Plug the other end into the ESD Wrist Strap Grounding  
receptacle in the lower right corner of the MMAC-Plus Chassis shown in  
4. The module is installed into the chassis by sliding it into slots and locking  
that the module slides in straight and engages the backplane connectors  
properly. When installing the module, ensure that both circuit cards are  
lower tracks of both cards.

Operation  
The 9F206-02 module, as shown in Figure 3-1, provides two repeater ports that  
extend the FNB bus outside the MMAC-Plus chassis. No bridging or routing is  
done in this module. Each port connects to both rings (Primary and Secondary) on  
each FNB (FNB-1 and FNB-2).

Flexible Network Bus (FNB)  
The FNB consists of two dual FDDI networks, FNB-1 and FNB-2, providing up to  
400 Mbps of data bandwidth. These FDDI networks are 100% ANSI FDDI-  
compliant supporting SMT (version 7.3), MAC, PHY, and PMD standards. This  
allows the FNB to traverse multiple MMAC-Plus hubs, or connect to any ANSI  
FDDI-compliant device, through standard A/B port connections.

Operation  
System Management Bus  
There are two management channels within the MMAC-Plus system: the SMB-1  
and the SMB-10. These buses provide out-of-band management and inter-module  
management communication. The 9F206-02 uses only the SMB-1 bus.  
The SMB-1 is a 1 Mbps management bus located within the MMAC-Plus. This bus  
is utilized by all diagnostic controllers in the system including connectivity  
modules, power supply modules and the environmental module. The SMB-1  
transports inter-chassis information between system components, such as power  
and environmental information, as well as diagnostic messages.  
System Diagnostic Controller  
This diagnostic controller is composed of a Z-80 microprocessor and its  
supporting logic. The diagnostic controller is designed to control the power-up  
sequencing of modules, monitor the 9F206-02 input and output parameters, as  
well as monitor the temperature, and control the SMB LANVIEW LED. The  
diagnostic controller on the 9F206-02 is also responsible for reporting the FNB and  
front panel connectivity status to network management. The information  
gathered by the diagnostic controller is available to the network manager via  
local/remote management and the LCD located on the Environmental Module.  
The 9F206-02 has been designed so that in the event of a diagnostic controller  
fault, the 9F206-02 will continue to function.  
DC/DC Converter  
The DC/DC converter converts the 48 VDC on the system power bus to the  
necessary operating voltages for its host network services module. The diagnostic  
controller controls the operation of the DC/DC converter.  
FNB Interface  
MMAC-Plus modules are designed with one of two attachment policies. One  
allows a module to dual attach to either FNB-1 or FNB-2; the second allows dual  
attachment to both FNB-1 and FNB-2. The 9F206-02 has dual attachment to the  
FNB backplane, connecting to both FNB-1 and FNB-2. These flexible  
configuration options make the MMAC-Plus ideal for networks designed to  
Bridge/Route multiple lower speed LANs to FDDI and/or networks designed  
using an FDDI collapsed backbone.

The CPU handles all low level SMT functions as well as module configuration

level communication between modules in the MMAC-Plus chassis.
