CPX8216 and CPX8216T Installation and Use (6806800A52C)
Chapter 2 System Architecture

The Active/Passive Configuration
In the active/passive configuration, one CPU manages all twelve I/O slots, much like in the
simplex configuration. In addition, the second CPU serves as a warm standby, ready to run the
system in the event of a failure on the active system.
The active/passive configuration is illustrated in the following figure.
The Active/Active or Load-Sharing Configuration
In the load sharing configuration, each CPU manages six of the twelve I/O slots, much like a
dual 8-slot system with the added benefit of one CPU being able to control all twelve I/O slots
if the other CPU fails. It is important in a load-sharing configuration to note that the total critical
activity does not exceed the capabilities of a single CPU, as either one of the CPUs must be
ready to take over the load carried by the other.
