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 pr
essure.

The Reset Switch
SMB
CPU
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.

Setting the FNB Switch
The 9W111-08 module can attach to ether FNB-1 or FNB-2. Figure 2-3 shows the
location of the FNB switch, SW201. When this switch is up (toward the top of the
module) the 9W111-08 attaches to FNB-2. When down, it attaches to FNB-1.

Local Management Console
Local Management is accessed by attaching a management console at the RJ-45
COM port of the 9W111-08. 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 9W111-08 WAN Router module is a eight port Wide Area Net router. Up to
eight 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.

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. 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 9W111-08 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 9W111-08 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.
3-2
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 9W111-08 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. 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.
CPU
The CPU provides the SNMP protocol stacks, as well as support for industry
standard MIBs.
