Subsequent to the default, the system software must determine the
configuration of the system and then proceed to change it.
System Processor Configurations
The CPX8216 is a flexible system that allows for multiple configurations
of processor control, I/O redundancy, and peripheral configurations. The
following sections briefly touch on possible configurations.
As noted above, there are three possible processor/control configurations:
❏ A simplex system containing a single CPU-HSC pair controlling
both I/O domains
❏ An active/passive configuration similar to the simplex
configuration, but providing a warm backup for both the CPU and
the HSC
❏ An active/active or load-sharing configuration in which each CPU
runs a single domain while also serving as a backup to the other
CPU.
Note H.110 traffic and HA Linux do not support a load-
sharing configuration.
The following sections give a general description of these configurations.
The Simplex Configuration
Because of the flexible nature of the CPX8216, it is possible to configure
it with different levels of redundancy and availability. For applications
which do not require the benefits of full high availability, it is possible to
configure the CPX8216 as a simplex, 16-slot system. This configuration
provides the benefits of redundant power supplies and the system
monitoring capabilities of the fully redundant configuration.
