If a Computer System Problem Occurs
If you have a problem with your computer system, first read Appendix C, Solving
Powerup Problems and Exiting the DG/UX Installer." It lists problems that could
occur during powerup and provides suggestions that you can use to solve these
problems.
If your computer passes powerup testing but still indicates a hardware problem, you
might want to run a diagnostic test on the system or a particular component. Refer to
Using AViiON

System Diagnostics for a description of the diagnostics available for
your system, and instructions on how to run them.
If you cannot resolve the problem yourself, contact Data General as described in the
Preface. If, after calling the Data General Service Center, you determine that a CRU
needs replacement, refer to Chapter 2 if the CRU is external. Follow the procedures
for removing and installing an internal CRU in subsequent chapters of this manual
after you have reviewed the appropriate sections of this chapter. Refer to Chapter 4 if
the CRU is an external SCSI device.
CAUTION: Before attempting to replace or add a CRU, read the section in this
chapter on Avoiding Electrostatic Discharge (ESD) Damage" so that you
do not damage the replacement or add-on CRU.
NOTE: If you have determined that the problem is in the peripheral housing unit
(PHU), refer also to the manual
Installing and Operating the Model
10565 Peripheral Housing Unit. If you have determined that the
problem is in the combined storage subsystem deskside chassis
(CSS2/DC), you will need the manual Installing and Maintaining the
CSS2/DC.
Reviewing System Specifications
This section contains information you should know before removing or installing any
hardware equipment in your computer system. It specifically covers the following
procedures you should perform before unpacking or installing a new internal option:
•
Review your system specifications to ensure hardware and software support for
any planned additions to your computer system.
•
Calculate your system's power requirements to ensure that the configuration you
plan doesn't exceed the limits of your power supply.
Verifying Support for Your Configuration
This section outlines factors you should consider as you plan and review the type,
number, and arrangement of the various hardware and software elements that make
up your computer system. We refer to these combined factors as your system
configuration .
•
Review the options listed in Chapter 1 and Appendix A to determine whether your
system supports the configuration you want.
