router. Onefront panel network connections can be made to this module and
routed to any other MMAC-Plus module via the FNB bus.
Features
Processor
The 9F106-01 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.
System Management
The 9F106-01 provides an interface to the System Management Bus (SMB-1) for
intermodule management.
Connectivity
The 9F106-01 provides one dual attached FDDI interface using two standard
Cabletron FPIMs.
Routing
The 9F106-01 provides Routing between the front panel interface and/or to any
other module in the chassis via FNB -1 or FNB -2 of the FNB bus. IEEE 802.1d
Spanning Tree Protocol is supported in all bridging functions.

Introduction
1-2
Management Information Base (MIB) Support
The 9F106-01 module provides MIB support including the following:
• IETF FDDI MIB
• IETF MIB II
LANVIEW LEDs
The 9F106-01 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.
Hot Swapping
The 9F106-01 can be installed or removed from the chassis while the MMAC-Plus
is powered up without affecting the operation of the remaining modules in the
chassis.
For a complete list of supported MIBs, refer to the release notes provided in the
module package.

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. 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 1.
4. Remove the module from the plastic bag. Observe all precautions to prevent
damage from Electrostatic Discharge (ESD).
5. Carefully examine the module, checking for damage. If any damage exists,
DO NOT install the module. Contact Cabletron Systems Technical Support
immediately.
6. Before installing the MMAC-Plus cards into the chassis, ensure that the
bottom and top plastic tabs are unlocked. Slide the card into an available slot
and ensure that the circuit card is between the card guides, as shown in
Figure 1. Check both the upper and lower tracks. Take care that the module
slides in straight and engages the backplane connectors properly. Lock down
the top and bottom plastic tabs at the same time, applying even pressure.

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.
Figure 2-2. The Reset Switch
Local Management Console
Local Management is accessed by attaching a management console at the RJ-45
CON port of the 9F106-01. The console connection supports a Digital Equipment
Corporation VT 320™ terminal or PC emulation of one of these terminals.
Table 2-1 lists the setup requirements for the local management console. If your
terminal is a Digital Equipment Corporation VT 320™ terminal, press F3 to access
the Setup Directory. If you have a terminal emulation of the Digital Equipment
terminals, refer to your equipment user manual for setup procedures.

Operation
The 9F106-01 FDDI Router module is a two port router. One front panel network
connection can be made to this module and is routed to any other port and to any
other MMAC-Plus module via the FNB bus.

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 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.
System Management Buses
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. These include 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. Periodic
loop-back tests are performed by all modules that share this bus to ensure the
validity of SMB-1.
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 9F106-01 input and output power
parameters, keep watch over the main host processor, as well as monitor the
temperature and control the SMB LANVIEW diagnostic LED. 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 9F106-01 have been designed so that in the event of a diagnostic controller
fault, the modules 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.
