INTRODUCTION

Welcome to Cabletron Systems 7C04 Workgroup SmartSwitch Chassis User’s Guide. This manual describes the physical characteristics, specifications, and capabilities of the 7C04 Workgroup SmartSwitch Chassis.

1.1 USING THIS MANUAL

Chapter 1,Introduction, discusses the features of the 7C04 Chassis.

Chapter 2,Installation, explains the 7C04 Chassis’ power supply module, and how to install that power supply module.

Chapter 3, Troubleshooting, explains the LANVIEW® LEDs of the 7C04 Chassis’ power supply module.

Chapter 4,Technical Specifications, explains the location requirements and operating specifications of the 7C04 Chassis.

1.2 USING THE SMARTSWITCH MANUAL SET

Each SmartSwitch interface module that can be inserted in the 7C04 Chassis 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 the7E03-24Module.

The management module of the 7C04 Chassis 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.

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 the7E03-24Module only.

Introduction

1.3 CHASSIS OVERVIEW

The 7C04 Chassis (Figure 1-1)is arack-mountable,multi-media,switching center. The chassis is astand-alonedevice that features a removable power supply. Two fans within the power supply provide system cooling. LANVIEW LEDs on the power supply indicateat-a-glancedevice status.

The chassis has four module slots. The slots are numbered from top to bottom; the top slot is number one the bottom slot is number four. The 7X00 Module must be inserted in the chassis’ top slot (slot one). The other three slots can support nearly any combination of Ethernet, Token Ring, FDDI, and ATM SmartSwitch interface modules1.

Figure 1-1.7C04 Workgroup SmartSwitch Chassis

Data from each SmartSwitch interface module (regardless of front panel technology) is relayed along the SmartSwitch Bus on the 7C04 Chassis’ backplane to the 7X00 Module. All switching functions are performed by hardware components on the 7X00 Module. No external bridges or routers are required to transfer data from one point to another within the chassis.

Introduction

1.3.1 7X00 SmartSwitch Controller Module

The 7X00 SmartSwitch Controller Module is the only processing and management element in the 7C04 Chassis. The 7X00 Module has no front panel data ports. All data enters and exits the 7X00 Module via the SmartSwitch Bus on the chassis’ 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 (including the status of the chassis’ power supply and fans).

Note: The 7X00 Module is nothot-swappable.Because the 7X00 Module is the only processing/management module in the 7C04 Chassis, removing the 7X00 Module will sever communications to all SmartSwitch interface modules in the 7C04 Chassis.

1.3.2 SmartSwitch interface modules

SmartSwitch interface modules in a 7C04 Chassis communicate freely with each other via the chassis’ SmartSwitch Bus and 7X00 SmartSwitch Controller Module. SmartSwitch interface modules can be installed or removed from the 7C04 Chassis at any time without impacting the rest of the network.

Introduction

1.3.3 Operations

Data entering through a front panel of a SmartSwitch interface module in the 7C04 Chassis is converted by the module’s hardware into a common “canonical” format. Canonical frames are forwarded along the chassis’ 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 frames are filtered or forwarded.

Traditional Switch

When operating as a traditional switch (a store-and-forwardswitch using the 802.1d Spanning Tree protocol), the 7X00 Module’s SmartSwitch Core searches for the frame’s destination address in the module’s connection table.

If the frame’s destination address is found in the connection table, the frame is forwarded to that specific destination via the chassis’ SmartSwitch Bus.

If the frame’s destination address is not found in the connection table, the frame is flooded to all of the SmartSwitch interface modules in the chassis via the chassis’ SmartSwitch Bus. The frame’s destination address is added to the module’s connection table.

SecureFast Packet Switch

When operating as a SecureFast Packet Switch, the 7X00 Module’s SmartSwitch Core searches for the frame’s destination addresssource address (DA-SA)pair and receive port in the module’s connection table.

If the frame’s entry is found in the connection table, the frame is forwarded to a specific destination via the chassis’ SmartSwitch Bus.

1-4

Introduction

If the 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 chassis’ SmartSwitch Bus, and a corresponding entry is written to the receiving module’s connection table. Otherwise, the frame is dropped.

1.4 SITE GUIDELINES

When choosing a location for the 7C04 Chassis, the following guidelines must be followed to ensure satisfactory network performance.

An unrestricted free surface area of 43.2 cm. (17 in.) wide,

34.8cm. (13.7 in.) deep and 16 cm. (6.3 in.) high must be available for the enclosure.

If the chassis is to be placed on a shelf, the shelf must be capable of supporting 13.5 kg. (30 pounds) of static weight.

If the chassis is to be rack mounted, care must be taken to ensure that the rack used will support the chassis and that the rack will remain stable with the chassis inserted. In order to allow proper cooling within the rack, there must be 7.6 cm. (3 in.) of clearance above the unit and 5 cm. (2 in.) of clearance on either side of the chassis in addition to the unrestricted free surface area previously detailed.

A standard three-prongpower receptacle must be located within

21.13meters (7 feet) of the chassis.

The temperature of the location surrounding the chassis must be maintained between 5° and 40°C (41° to 104°F). Temperature changes of greater than 10°C (18°F) per hour must not occur.
