Chapter 1 Introduction The 9T101-04 Token Ring Router module, shown in Figure 1-1, is a four port Token Ring router. Up to four front panel network connections can be made to this module and they can be routed to any other port and to any other MMAC-Plus module via the FNB bus. Features Processor The 9T101-04 is equipped with an advanced IDT R4600 Fourth Generation 64 bit RISC microprocessor. This microprocessor provides a platform for all management functions within a scalable RISC-based architecture.
Introduction Management Information Base (MIB) Support All concentrator modules provide MIB support including the following: • • NOTE IETF Source Routing Bridging MIB IETF MIB II For a complete list of supported MIBs, refer to the release notes provided in the module package. LANVIEW LEDs The 9T101-04 uses LANVIEW: the Cabletron Systems built-in visual diagnostic and status monitoring system. With LANVIEW LEDs, you can quickly identify the device, port, and physical layer status at a glance.

Chapter 2 Installing the MMAC-Plus Module The MMAC-Plus module may be installed into any of the 14 slots that are available. To install, follow the steps below: 1. Remove the blank panel, covering the slot 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. 2. Carefully remove the module from the shipping box. (Save the box and packing materials in the event the module must be reshipped.) 3.

Lock down the top and bottom plastic tabs at the same time, applying even pressure. Figure 2-1.
The Reset Switch The Reset Switch The Reset switch is located on the front panel, under the top plastic tab, as shown in Figure 2-2. It serves two functions: • • Pressing the Reset switch twice within three seconds causes the processor 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. SNMP management may be used to disable this switch to enhance module security.

Chapter 3 Operation The 9T101-04 Token Ring Router module is a four port router. Four front panel network connections can be made to this module and they can be routed to any other port and to any other MMAC-Plus module via the FNB bus. DC/DC Converter Token Ring port SMB-1 System Diagnostic Controller Token Ring port CPU FNB-1 or FNB-2 Token Ring port Token Ring port Front Panel CON Ports Figure 3-1.
Operation Flexible Network Bus (FNB) The FNB consists of two dual FDDI networks, the 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. System Management Buses The SMB-1 is a 1 Mbps management bus located within the MMAC-Plus.
FNB Interface FNB Interface MMAC-Plus modules are designed with one of two attachment policies. One allows dual attachment of a module to either FNB-1 or FNB-2; the second allows dual attachment to both FNB-1 and FNB-2. The 9T101-04 has one dual attachment to the FNB backplane, connecting to either FNB-1 or FNB-2. The module can insert into the FNB or bypass it.
