Chapter 1 Product Overview
Route Processors
Route Processors
The route processor contains most of the system memory components and the
main system processor, which includes the network management processor for the
system software. You can install up to two route processors in slots 4 and 8 of the
chassis. The chassis supports fault tolerance by allowing a secondary (or
redundant) route processor to take over if the primary route processor fails. This
redundant route processor runs in standby mode. Figure 1-2 shows the route
processor, which maintains and executes the management functions that control
the chassis.

Switch Modules
You can install up to three switch modules in slots 5 to 7 of the chassis. Two
switch modules are required for operation. By default, switch modules 5 and 7 are
primary and switch module 6 runs in standby. The third switch module provides
redundancy for only one of the two active modules in the chassis. The standby
switch module automatically becomes active in the event that you remove one of
the switch modules from the system. To force the standby switch module to
become active, use the redundancy preferred-switch-card-slots command.
Figure 1-3 shows the switch module.
