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 the 7E03-24 Module.

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 the

7E03-24 Module only.

Introduction

1.3 CHASSIS OVERVIEW

The 7C04 Chassis (Figure 1-1) is a rack-mountable, multi-media,

switching center. The chassis is a stand-alone device that features a

removable power supply. Two fans within the power supply

provide system cooling. LANVIEW LEDs on the power supply

indicate at-a-glance device 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 modules

Figure 1-1. 7C04Workgroup 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.

A7E03-24 Module can not be inserted in the bottom slot (slot four) of a 7C04

Chassis.

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 not hot-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-forward

switch 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 address-

source 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.

Introduction

1-5

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,

34.8 cm. (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.

• Astandard three-prong power receptacle must be located within

21.13 meters (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.
