Card Enclosure Diagrams - IBM AS/400e User Handbook Manual

There are several new concepts in the AS/400 system, such as Multi-Adapter Bridges,
Multi-Adapter Bridge Boundaries, and PCI Buses, that are defined later in this section.
Knowledge of these new concepts is required to understand the card rules defined later in
this chapter. All the discussions in this section refer to the following diagram containing the
layouts of the various card enclosures.
