Chapter 3
Starting and Stopping
Your Computer System
The first section of this chapter describes a normal powerup sequence. After you
install your computer system hardware (for the first time, as described in Chapter 2, or
after hardware maintenance, as described in Chapter 6), follow the steps in the
Powering Up" section of this chapter to start the computer and boot your operating
system. The last section of this chapter explains how to properly power down, reset
and restart the computer system.
Starting the Computer System
Each time you apply ac power to your computer system, a series of diagnostic tests in
the firmware verify that the hardware is functioning well enough to run your
operating system and its applications. Appendix C, Solving Powerup Problems and
Exiting the DG/UX Installer," describes what you can do if your computer system fails
to successfully complete powerup diagnostic tests. The following sections of this
chapter describe how to power up your system, and describe what you should do the
first time you start up your AViiON 530 or 4600 series computer.
Once you install and customize your operating system, the sequence of events and
displays you see after powerup testing will change; refer to your operating system
documentation for information on booting installed and customized software.
NOTE: We strongly recommend that you familiarize yourself with your operating
system installation procedures and documentation before you power up for
the first time. You should also determine whether you want to run hardware
diagnostics before installing your operating system, and whether you need to
alter any hardware configuration parameters from the defaults listed in
Chapter 2.
Powering Up
This section describes how to power up your computer system. It is important that
you turn power on to the computer unit and peripherals in the proper sequence, and
that your computer system completes the powerup testing properly.
CAUTION: Verify that the computer unit, monitor, peripherals, and all power cords
have appropriate ac power voltage for your site before turning on power to
your computer system, as described in Chapter 2.
