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.
