Preface
We wrote this manual for anyone who sets up and maintains A iiON530 and
4600 series computer system hardware. Although it addresses readers with some
computer hardware experience, you do not need knowledge of A iiON or RISC-based
computer technology to use this manual.
The first three chapters of this manual describe how to unpack, set up, and start a
basic new computer system. They cover a hardware installation sequence that ends
with you ready to install your system software. Subsequent chapters explain how to
set up and connect external mass-storage units, and how to customize operating
parameters for devices connected directly to the system board. The final six chapters
in this manual provide detailed information and illustrated instructions for replacing
failing parts and for adding mass-storage devices, expansion memory, and option
boards to an installed system. Appendixes provide technical specifications for computer
system hardware, instructions for using the System Control Monitor (SCM), and
suggestions for solving powerup problems.
NOTE: This manual does not describe how to set up or install MEbus option
boards, or the devices that connect to them. If your system includes
MEbus options, refer to Setting Up and Installing VMEbus Options in
AViiONSystems (DGC part number 014-001867) for instructions.

Reading Paths
The following reading paths explain which chapters and sections you should read and
in what order, depending on the task you need to do.
Reading Path for Setting Up a New Computer System
Review site requirements, and then unpack and inventory your system, as described in
Chapter 1. Then read Chapter 2, following those instructions that apply to your
configuration. Read Chapter 3, Starting and Stopping Your Computer System" before
you power up your new computer system.
•If your system includes external SCSI devices or subsystems, set them up as
described in Chapter 4 before continuing with the instructions in Chapter 3 to start
your system.
•If your system includes MEbus options (such as a terminal controller or
asynchronous device controller), set up and connect the appropriate devices as
described in the device-specific documentation and Setting Up and Installing
VMEbus Options in AViiONSystems. Then continue with the instructions in
Chapter 3 to start your system.
•If your system includes devices connected to the system board whose operating
parameters conflict with the defaults listed in Chapter 2 and which are required for
the first powerup, read the appropriate instructions in Chapter 5 before continuing
with the instructions in Chapter 3 to start your system.
Reading Path for Powerup Procedures or Problems
Refer to Chapter 3, Starting and Stopping Your Computer System," for a description
of the sequence your computer system undergoes when powering up normally. Refer
to Appendix C, Solving Powerup Problems and Exiting the DG/UXInstaller," for
troubleshooting suggestions. For steps to properly shut down the computer system,
refer to the last section of Chapter 3, Shutting Down the Computer System."
Reading Path for Expanding the Computer System
NOTE: To add MEbus options to your system, first verify your proposed system
configuration as described in Chapter 6; then refer to Setting Up and
Installing VMEbus Options in AViiONSystems.
