Introduction
The 9F310-02 and 9F315-02 are three port switch modules with two front panel
FDDI interfaces and one INB-1 backplane interface. The external FDDI networks
are connected to the modules using standard FDDI A/B ports on the front panel.
The 9F310-02 uses multi mode fiber, and the 9F315-02 uses single mode fiber optic
cables for this connection. The 9F310-02 and 9F315-02 modules employs the Fast
Packet Switch (FPS), a high performance switch design, and the Intel i960 micro-
processor. The modules can redirect one or both of its front panel FDDI Interfaces
to the FNB backplane, creating an INB-1 to FNB bridge/switch product that
allows a migration from FNB modules to INB-1 modules.
Features
Processor
The 9F310-02 and 9F315-02 are equipped with an advanced Intel i960
microprocessor. This microprocessor provides a platform for all management
functions within a scalable RISC-based architecture.
Packet Switch Engine
The 9F310-02 and 9F315-02 module incorporates the Fast Packet Switch (FPS), a
collection of custom ASlCs designed specifically for high speed switching. The
FPS bus is 64 bits wide with a bandwidth of 320 Mbps. Since all frame translation,
address lookups, and forwarding decisions are performed in hardware, the
9F310-02 and 9F315-02 can obtain a throughput performance of greater than
150K pps.
Management
The 9F310-02 and 9F315-02 modules have two full implementations of SMT
(Version 7.3), one per interface, and SNMP for local and remote management.
Local management is provided through the RS-232 Com ports on the MMAC-Plus
Environmental Module using a standard VT-220 terminal or emulator. Remote
management is possible through Cabletron’s SPECTRUM or any SNMP
compliant management tool as well as telneting to the module. Management
features including module insert/bypass control, MAC placement, front
panel/FNB configuration, and SMT statistics. Bridging statistics on both FDDI

interfaces provide frames filtered, frames forwarded, and all Spanning Tree
Protocol parameters. The 9F310-02 and 9F315-02 modules support the IETF FDDI
MIB (RFC-1512), IETF MIB ll (RFC-1213), IETF BRIDGE MIB (RFC-1493), and a
host of Cabletron enterprise MIBs. In addition, the front panel provides LEDs for
FDDI link status per port as well as transmit and receive activity.
Connectivity
The 9F310-02 and 9F315-02 modules have one interface to the INB-1, two front
panel FDDI interfaces, or two FNB interfaces to the MMAC-Plus FNB backplane.
The front panel A/B port connections are via standard fiber FDDI MIC
connectors. The INB-1 interface is fixed, however, and the two FDDI interfaces
can attach to one or both of the front panel connectors, one or both of the FNB
interfaces (FDDI-1 or FDDI-2), or one of each.
Management Information Base (MIB) Support
Both 9F310-02 and 9F315-02 provide MIB support including:
• IETF FDDI MIB
• IETF MIB II
• IETF Bridge MIB
• a host of Cabletron Enterprise MIBs.
LANVIEW LEDs
The 9F310-02 and 9F315-02 use 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.
For a complete list of supported MIBs, refer to the release notes provided in
the 9F310-02 and 9F315-02 package.

Installing the MMAC-Plus modules
The 9F310-02 and 9F315-02 modules occupy two slots in the MMAC-Plus chassis.
The modules must be installed with the left side (as viewed from the front) in an
odd numbered slot, and the right side in an even numbered slot.
To install the 9F310-02 and 9F315-02, follow the steps below:
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. Carefully remove the module from the shipping box. (Save the box and
packing materials in the event the module must be reshipped.)
4. 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 2-1.
5. Remove the module from the plastic bag. Observe all precautions to prevent
damage from Electrostatic Discharge (ESD).
6. Carefully examine the module, checking for damage. If any damage exists,
DO NOT install the module. Contact Cabletron Systems Technical Support
immediately.
7. The modules are installed into the chassis by sliding them into slots and
locking down both the top and bottom plastic tabs, as shown in Figure 2-1.
Take care that the module slides in straight and engages the backplane
connectors properly. When installing the module, ensure that both circuit
cards are between the card guides, as shown in Figure 2-1. Check both the
upper and lower tracks of both cards.
The INB Terminator Modules must be installed on the rear of the chassis before powering
up this module. Refer to the INB Terminator Modules Installation Guide for
information and installation procedure.

The Reset Switch
The Reset Switch
The Reset switch is located on the rightmost 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 (i960)
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.

Operation
The 9F310-02 and 9F315-02 modules are capable of bridging/switching any three,
of five possible interfaces, depending on how it is configured. The INB-1
connection is always fixed. When configuring the module, the decision is made to
connect both front panel ports, both FNB ports, or one front panel and one FNB
port to the bridge.
As shown in Figure 3-1, packets may be received at the front panel FDDI ports,
the FNB rings (FNB-1 and/or FNB-2), and/or the INB-1 bus, according to the user
configuration. These packets are converted into canonical format. The Fast Packet
Switching circuitry decides from header information where the packets should be
sent. They are then converted from canonial format to the proper format for that
interface.

System Management Buses
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.
SMB-1 Bus
The SMB-1 is a 1Mbs 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. The SMB-1
transports inter-chassis information between system components, such as power
and environmental information, as well as diagnostic messages. Periodic
loop-back test are preformed by all modules which share this bus to ensure the
validity of SMB-1. In the event a failure is detected on SMB-1, the SMB-10 may be
used as an alternate communication channel.
SMB-10 Bus
The SMB-10 is a 10Mbs management bus located within the MMAC-Plus which is
also used for inter-chassis communication of modules as well as serving as an
out-of-band management channel into the MMAC-Plus. The SMB-10 is
externalized from the chassis via an optional Ethernet Port Interface Module
(EPIM) located on the front of the Environmental Module. Through an EPIM
connection, full SNMP management of the MMAC-Plus is available out-of-band
from user data. Modules which share the SMB-10 bus periodically send out loop-
back packets to ensure the validity of SMB-10. In the event a fault is detected on
the SMB-10, the SMB-1 can be used as an alternate communication channel by the
modules.
System Diagnostic Controller
This diagnostic controller is composed of a Z-80 microprocessor and it’s
supporting logic. The diagnostic controller is designed to control the power-up
sequencing of modules, monitor the 9F310-02 and 9F315-02 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. Although the
diagnostic controller and the main host processor can operate independent of
each other if needed, they exchange information about each others status and
overall module condition. The information gathered by the diagnostic controller
is available to the network manager via local/remote management and the LCD
located on the environment module. The 9F310-02 and 9F315-02 have been
designed so that in the event of a diagnostic controller fault, the 9F310-02 and
9F315-02 will continue to function.
