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

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.

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.
