INTRODUCTION
Welcome to Cabletron Systems 7C03 MMAC SmartSwitch
Installation Guide . This manual is a simple installation and reference
guide. The 7C03 MMAC SmartSwitch is a unique self-contained
module that can be placed into an MMAC series chassis

.
1.1 USING THIS MANUAL
Chapter 1,
Introduction
, discusses the features of the 7C03
MMAC SmartSwitch.
Chapter 2,
Installation
, explains the process of inserting the 7C03
MMAC SmartSwitch in an MMAC chassis.
Chapter 3,
Technical Specifications
, explains the physical and
operational specifications for the 7C03 MMAC SmartSwitch.
1.2 USING THE SMARTSWITCH MANUAL SET
Each SmartSwitch interface module that can be inserted in the
7C03 MMAC SmartSwitch is shipped with a module user’s guide.
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.
The user’s guide explains the 7X00 Module’s physical
characteristics, installation procedures, and how to locally manage
the SmartSwitch interface modules in the chassis.

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.
