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

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 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.  
1-3  
 
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.  
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,  
34.8 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.
