For example, the 7E03-24 Ethernet SmartSwitch Interface Module
User’s Guide explains the physical characteristics, specifications,
and installation procedures of the 7E03-24 Module.
The management module of the 7C03 MMAC SmartSwitch is
described in the 7X00 SmartSwitch Controller Module User’s Guide.

Refer to Chapter 2 of this installation guide for information and
considerations regarding the placement of a 7C03 MMAC SmartSwitch in
an MMAC series chassis.

Introduction
In addition, any local management information that is specific to a
particular SmartSwitch interface module is described in a module
specific local management appendix. For example, the 7E03-24
Ethernet SmartSwitch Interface Module Local Management Appendix
explains information that is specific to local management of the
7E03-24 Module only.
1.3 7C03 MMAC SMARTSWITCH OVERVIEW
The 7C03 MMAC SmartSwitch (Figure 1-1) is a metal enclosure
that can be placed into two module slots of an MMAC chassis. The
7C03 MMAC SmartSwitch attaches to the MMAC chassis’ power
bus, but does not attach to the data channels on the chassis’
backplane. The 7C03 MMAC SmartSwitch can be installed or
removed from the MMAC chassis at any time without affecting the
operation of the rest of the network.
The 7C03 MMAC SmartSwitch has three module slots. The left-
most slot (slot one) is reserved for the 7X00 SmartSwitch Controller
Module, a management module that contains a Smart Switching
engine. The other two slots can support any combination of
Ethernet, Token Ring, FDDI, and ATM SmartSwitch interface
module
s .
Spanning the rear wall of the 7C03 MMAC SmartSwitch is the
SmartSwitch Bus. All modules that are inserted into the 7C03
MMAC SmartSwitch connect to the SmartSwitch Bus. All
communication between modules within the 7C03 MMAC
SmartSwitch is achieved via the SmartSwitch Bus.
All data and management information from SmartSwitch interface
modules within the 7C03 MMAC SmartSwitch is relayed along the
SmartSwitch Bus to the 7X00 Module. All switching functions are
performed by the 7X00 Module. Thus, within the confines of the
7C03 MMAC SmartSwitch, data can be freely transmitted
regardless of front panel technology. With no external bridges or
routers, the transfer of data from one point to another within the
7C03 MMAC SmartSwitch is virtually direct.

Introduction
1-3
Figure 1-1. 7C03 MMAC SmartSwitch
Because the 7C03 MMAC SmartSwitch does not attach to the data
channels on the backplane of an MMAC chassis, data can not be
transmitted internally from SmartSwitch interface modules to the
other modules in the MMAC chassis. However, data can be
transmitted externally from SmartSwitch interface modules to any
other destination (in the same chassis or elsewhere) via
connections to the front panel of any SmartSwitch interface
module.

Introduction
1.3.1 7X00 SmartSwitch Controller Module
The 7X00 SmartSwitch Controller Module is the only processing
and management element in the 7C03 MMAC SmartSwitch. The
7X00 Module has no front panel data ports. All data enters and
exits the 7X00 Module via the SmartSwitch Bus on the 7C03
MMAC SmartSwitch’s backplane. The 7X00 Module directs
incoming data to its intended destination by using a group of
Application Specific Integrated Circuits (ASICs) collectively
known as the SmartSwitch Core. All packet switching functions
are performed in the module’s SmartSwitch Core. The
SmartSwitch Core is capable of switching up to 750,000 frames per
second. The firmware on a 7X00 Module determines the
SmartSwitch Core’s operating mode (traditional switch or
SecureFast Packet Switch). The module’s CPU (an i960
microprocessor
®
) is used to collect management data of the
SmartSwitch system.
Note: The 7X00 Module is not hot-swappable. Because the 7X00
Module is the only processing/management module in the 7C03
MMAC SmartSwitch, removing the 7X00 Module will sever
communications to all SmartSwitch interface modules in the
7C03 MMAC SmartSwitch.
1.3.2 SmartSwitch interface modules
SmartSwitch interface modules in a 7C03 MMAC SmartSwitch
communicate freely with each other via the 7C03’s SmartSwitch
Bus and 7X00 SmartSwitch Controller Module. SmartSwitch
interface modules can be installed or removed from the 7C03
MMAC SmartSwitch at any time without impacting the rest of the
network.

Introduction
1-5
1.3.3 Operations
Data packets entering through the front panel of a SmartSwitch
interface module in the 7C03 MMAC SmartSwitch are converted
by the module’s hardware into frames that have a common
“canonical” format. Canonical frames are forwarded along the
7C03’s SmartSwitch Bus to the 7X00 Module in slot one. The
configuration of the 7X00 Module (either traditional switch or
SecureFast Packet Switch) determines the manner in which
canonical frames are processed.
When operating as a traditional switch (a store-and-forward
switch using the 802.1d Spanning Tree protocol), the 7X00
Module’s SmartSwitch searches for the canonical frame’s
destination address in the module’s connection table. If the
canonical frame’s destination address is found in the connection
table, the frame is forwarded to that specific destination via the
7C03’s SmartSwitch Bus. If the canonical frame’s destination
address is not found in the connection table, the frame is flooded to
all of the SmartSwitch interface modules via the 7C03’s
SmartSwitch Bus.
When operating as a SecureFast Packet Switch, the 7X00 Module’s
SmartSwitch searches for the canonical frame’s destination
address-source address (DA-SA) pair and receive port in the
module’s connection table. If the canonical frame’s entry is found
in the connection table, the frame is forwarded to a specific
destination via the 7C03’s SmartSwitch Bus. If the canonical
frame’s entry is not found in the connection table, a request is sent
to the system’s Virtual Network Services (VNS). The VNS checks
its virtual routing tables and policy sections. If the frame’s
information appears in the VNS’ virtual routing tables and the
VNS’ policy section contains an entry that verifies that the frame’s
source and the frame’s destination are a valid combination, then
the frame is forwarded to its destination via the 7C03’s
SmartSwitch Bus, and a corresponding entry is written to the
receiving module’s connection table. Otherwise, the frame is
dropped.

CHAPTER 2
INSTALLATION
This chapter contains instructions for unpacking and installing the
7C03 MMAC SmartSwitch in an MMAC chassis. The 7C03 MMAC
SmartSwitch can be installed in an MMAC-M5FNB or in an
MMAC-M8FNB chassis.
Note:
Because of the modular nature of the power supplies and interface
modules in the MMAC-M5FNB and MMAC-M8FNB chassis,
there is no one standard MMAC configuration that can be used as
a reference. The way you configure your MMAC-M5FNB or
MMAC-M8FNB chassis (number of power supplies, number and
types of interface and management modules) is determined by
your specific needs. Therefore, to insure that the power
requirements of your MMAC will not be exceeded by the addition
of a 7C03 MMAC SmartSwitch, we recommend that you contact
Cabletron Technical Support prior to installing the 7C03 MMAC
SmartSwitch.
2.1 UNPACKING THE 7C03 MMAC SMARTSWITCH
Unpack the 7C03 MMAC SmartSwitch by using the following
steps:
1. Remove the 7C03 MMAC SmartSwitch from the shipping box.
(Save the box and packing materials in the event the 7C03
MMAC SmartSwitch must be reshipped.)
2. Remove the 7C03 MMAC SmartSwitch from the plastic bag.
3. Examine the 7C03 MMAC SmartSwitch and check for damage.
If damage exists, DO NOT install the 7C03 MMAC
SmartSwitch; contact Cabletron Systems Technical Support.
Otherwise, install the 7C03 (see Section 2.2).

2.2 INSTALLING THE 7C03 MMAC SMARTSWITCH
Prior to installing the 7C03 MMAC SmartSwitch, please read the
note that appears on page 2-1.
To install the 7C03 MMAC SmartSwitch in an MMAC-M5FNB or
MMAC-M8FNB chassis, use the following steps and refer to
Figure 2-1.
1. Remove the blank panels covering the slots in which the 7C03
MMAC SmartSwitch will be installed. All other unused slots
must remain covered to ensure proper air flow and cooling.
2. Hold the 7C03 MMAC SmartSwitch by the top and bottom
handles and align the plastic rails on the top and bottom of the
7C03 MMAC SmartSwitch with the corresponding card guides
on the MMAC chassis.
3. Slide the 7C03 MMAC SmartSwitch straight into the chassis
until the 7C03 engages the backplane connectors.
4. Tighten the top and bottom thumb screws on the 7C03 MMAC
SmartSwitch.
5. You can now install the 7X00 Module and SmartSwitch
interface modules into the 7C03 MMAC SmartSwitch. Refer to
the applicable module user’s guide for detailed installation
instructions.
