Preface
This manual contains information that you will need to add VMEbus-related
hardware to your AViiON

system. It supplements your system’s setting up,
expanding, and maintaining manuals that list the VME options supported by your
particular model. You should also refer to your most recent Technical Notices,
software updates, and Release Notices for current information.
The first three chapters in this manual describe how to add and replace optional
controllers and adapters that communicate with your system’s central processing
unit over a VMEbus. Chapter 4 describes how to connect devices to the VME
controllers and adapters supported by Data General—most readers will need this
chapter alone.
WARNING: Unqualified personnel attempting to remove, install, or
service internal components or options in AViiON 5000, 6000,
7000, and 8000 series systems risk both personal injury and
damage to the system. Data General Corporation supports
the maintenance and expansion of these systems by qualified
Data General personnel only. Service by other than
Data General personnel may void product warranties. For
more information regarding Data General warranties, refer to
your Data General sales and field engineering contracts.
