personal injury.

Danger

notices appear on the following pages:

For a translation of the safety notices contained in this book, see the

System Unit Safety Information

,

order number SA23-2652.

Electrical Safety

Observe the following safety instructions any time you are connecting or disconnecting devices attached to

the system.

DANGER

An electrical outlet that is not correctly wired could place hazardous voltage on metal parts of

the system or the devices that attach to the system. It is the responsibility of the customer to

ensure that the outlet is correctly wired and grounded to prevent an electrical shock.

Use one hand, when possible, to connect or disconnect signal cables to prevent a possible

shock from touching two surfaces with different electrical potentials.

During an electrical storm, do not connect cables for display stations, printers, telephones, or

station protectors for communications lines.

D06

CAUTION:

This product is equipped with a three-wire power cable and plug for the user’s safety. Use this

power cable with a properly grounded electrical outlet to avoid electrical shock.

C01

DANGER

To prevent electrical shock hazard, disconnect all power cables from the electrical outlet before

relocating the system.

D01

xi

CAUTION:

This unit has more than one power supply cord. Follow procedures for removal of power from the

system when directed.

C28

CAUTION:

Energy hazard, remove power before servicing.

C22

CAUTION:

Energy hazard, remove all jewelry before servicing.

C29

xii 386/50 Service Guide

Laser Safety Information

CAUTION:

This product may contain a CD-ROM, DVD-ROM, or laser module on a PCI card, which are class 1

laser products.

C30

Laser Compliance

All lasers are certified in the U.S. to conform to the requirements of DHHS 21 CFR Subchapter J for class

1 laser products. Outside the U.S., they are certified to be in compliance with the IEC 825 (first edition

1984) as a class 1 laser product. Consult the label on each part for laser certification numbers and

approval information.

CAUTION:

All laser modules are designed so that there is never any human access to laser radiation above a

class 1 level during normal operation, user maintenance, or prescribed service conditions. Data

processing environments can contain equipment transmitting on system links with laser modules

that operate at greater than class 1 power levels. For this reason, never look into the end of an

optical fiber cable or open receptacle. Only trained service personnel should perform the

inspection or repair of optical fiber cable assemblies and receptacles.

C25, C26

xiv 386/50 Service Guide

Data Integrity and Verification

These computer systems contain mechanisms designed to reduce the possibility of undetected data

corruption or loss. This risk, however, cannot be eliminated. Users who experience unplanned outages,

system failures, power fluctuations or outages, or component failures must verify the accuracy of operations

performed and data saved or transmitted by the system at or near the time of the outage or failure. In

addition, users must establish procedures to ensure that there is independent data verification before relying

on such data in sensitive or critical operations. Users should periodically check our support websites for

updated information and fixes applicable to the system and related software.

xvi 386/50 Service Guide

About This Book

This book provides maintenance information that is specific to the 386/50, adapters, and attached devices

that do not have their own service information. It also contains Maintenance Analysis Procedures (MAPs)

that are not common to other systems.

MAPs that are common to all systems are contained in the

Diagnostic Information for Multiple Bus

Systems

.

This book is used by the service representative to repair system failures. This book assumes that the

service representative has had training on the system.

ISO 9000

ISO 9000 registered quality systems were used in the development and manufacturing of this product.

Highlighting

The following highlighting conventions are used in this book:

Bold Identifies commands, subroutines, keywords, files, structures, directories, and other items

whose names are predefined by the system. Also identifies graphical objects such as buttons,

labels, and icons that the user selects.

Italics

Identifies parameters whose actual names or values are to be supplied by the user.

Monospace Identifies examples of specific data values, examples of text similar to what you might see

displayed, examples of portions of program code similar to what you might write as a

programmer, messages from the system, or information you should actually type.

References to AIX Operating System

This document may contain references to the AIX operating system. If you are using another operating

system, consult the appropriate documentation for that operating system.

This document may describe hardware features and functions. While the hardware supports them, the

realization of these features and functions depends upon support from the operating system. AIX provides

this support. If you are using another operating system, consult the appropriate documentation for that

operating system regarding support for those features and functions.
