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.
Notice 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.
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 10-6 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 cm-2 or 8 x 103 W m2 sr-1.

Chapter 1 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.
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.

Chapter 2 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.

User-Accessible Components User-Accessible Components Figure 2-2 shows the various components that are accessible to the user. These consist of an eight position dip switch (explained in the next section) and sockets for replaceable PROMs. These will be used for future upgrades. Instructions for installing the components will be supplied with the upgrade kit. SMB-1 PROM Boot PROM DIP Switch Figure 2-2.

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: 2-6 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.

Installing the MicroLAN Module The Reset Switch 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. Reset Switch SMB CPU Figure 2-5.
Chapter 3 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).

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.
CPU CPU The CPU handles all low level SMT functions as well as module configuration requests. The CPU is also responsible for all environmental, power and system level communication between modules in the MMAC-Plus chassis.
Chapter 4 LANVIEW LEDs The front panel LANVIEW LEDs indicate the status of the module and may be used as an aid in troubleshooting. Shown in Figure 4-1 are the LANVIEW LEDs of the 9F206-02 module. FDDI 9F206-02 SMB and CPU SMB CPU FDDI Port Status 1 2 A Figure 4-1.
