notice indicates the presence of a hazard that has the potential of causing death or serious

personal injury. Danger notices appear on the following pages:

v xii

v 89

v 357

v 436

A

caution

notice indicates the presence of a hazard that has the potential of causing moderate or minor

personal injury. Caution notices appear on the following pages:

v 89

v 357

Note: For a translation of these notices, see

System Unit Safety Information

, order number SA23-2652.

Rack Safety Instructions

v Do not install this unit in a rack where the internal rack ambient temperatures will exceed 35 degrees C.

v Do not install this unit in a rack where the air flow is compromised. Any side, front or back of the unit

used for air flow through the unit must not be in direct contact with the rack.

v Care should be taken to ensure that a hazardous condition is not created due to uneven mechanical

loading when installing this unit in a rack. If the rack has a stabilizer it must be firmly attached before

installing or removing this unit.

v Consideration should be given to the connection of the equipment to the supply circuit so that

overloading of circuits does not compromise the supply wiring or overcurrent protection. To provide the

correct power connection to the rack, refer to the rating labels located on the equipment in the rack to

determine the total power requirement for the supply circuit.

v An electrical outlet that is not correctly wired could place hazardous voltage on the 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.

xi

Electrical Safety

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

the workstation.

In the system you are about to setup or service:

v The ac power interface connector is considered the main power disconnect device.

v This system has redundant power supply capabilities, meaning that it has the ability to have two power

supplies running simultaneously in the same system unit. When instructed to disconnect the power

source, ensure that all power cables have been unplugged.

DANGER

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

relocating the system.

D01

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.

xii 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

Safety Notices xiii

xiv 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 Service Guide

About This Book

This book provides maintenance information that is specific to the 286/C4 and 286/E4, as well as 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. In this book, the 286/C4 and 286/E4 are

hereafter referred to as the

system

.

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.

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.

ISO 9000

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