  • Page 7: Chapter 1 Introduction

    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.
  • Page 8 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...

    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.

  • Page 19: Chapter 3 Operation

    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).

  • Page 20: System Management Bus

    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.
