System Architecture
PICMG Compliance
The CPX8216 system is designed to be fully compliant with the
CompactPCI Hot Swap Specification developed by the PCI Industrial
Computers Manufacturing Group (PICMG). With the proper software
support and testing, it should be possible to integrate all proprietary and
third-party I/O modules which are compatible with this specification.
Further, the system allows the use of I/O modules which are not hot
swappable, but the system must be powered off when such modules are
inserted and extracted.

The CPX8216 also features the ability to hot swap system and nonsystem
processor boards, a feature which is beyond the scope of the PICMG
specification. As part of its commitment to open standards, Motorola will
propose that the processor hot swap capabilities of the CPX8216 be added
to the Hot Swap Specification. At this point, however, there are no third-
party CPU modules which are compatible with the CPX8216 system.

System Domains
The high availability and high slot count of the CPX8216 systems is made
possible by implementing two host CPU slots and multiple CompactPCI
bus segments in a single chassis. These bus segments, along with other
system resources are grouped into two logical domains, A and B, which
can be controlled by either host-HSC pair regardless of the bus segment the
host sits on. Domain A includes CompactPCI bus segment A (slots 1 to 8),
the power supply/fan tray modules and alarm controls. In the CPX8216,
domain B consists of the CompactPCI bus segment B (slots 9 to 16). For
further information on domain control or ownership, see the section,
