CPX8216 and CPX8216T Installation and Use (6806800A52C)

System Processor Configurations

The CPX8216 is a flexible platform that allows for multiple configurations of processor control,

I/O redundancy, and peripheral configurations. The following sections briefly touch on the 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.

The simplex configuration is illustrated in the following figure.
