You can install line cards in any order in the expansion slots. For example, you could install a module in the first slot
and leave the other slot empty. The RS 3000 provides non-blocking throughput regardless of the software features you
are using. Therefore, you do not need to load balance line cards by placing them in certain relationships.
2.4.2
Motherboard
The motherboard contains system-wide bridging and routing tables. Traffic that does not yet have an entry in the
lookup tables on individual line cards is handled by the motherboard. After processing traffic, the motherboard updates
the lookup tables in the line card that initially received the traffic. Consequently, the line cards learn how to forward
traffic.
Boot and Image Flash
The motherboard has a boot flash containing the RS 3000’s boot software and configuration files. The system software
image file resides on an internal flash chip and can be upgraded from a TFTP or BootP/TFTP server.
RAM Memory
The motherboard uses 128MB of RAM to hold routing and other tables. This RAM can be upgraded to 256MB.
