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 

 

explains information that is specific to local management of the 
7E03-24 Module only.

 

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

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.
