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.

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.

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 Figure 2-4.
4. The module is installed into the chassis by sliding it into slots and locking down both the top and bottom plastic tabs, as shown in Figure 2-4. Take care that the module slides in straight and engages the backplane connectors properly. When installing the module, ensure that both circuit cards are between the card guides, as shown in Figure 2-4. Check both the upper and lower tracks of both cards.

The Reset switch is located on the front panel, under the top plastic tab as shown in Figure 2-5. It serves two functions:
Pressing the Reset switch twice within three seconds causes the main CPU to reset.
Pressing and holding the switch on for three or more seconds causes the module to shutdown. Pressing and holding again for three seconds restarts the module.

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 FDDI­compliant 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.
