Preface

The Sun Enterprise 220R Server Service Manual provides detailed procedures that
describe the removal, installation, and replacement of serviceable parts and options
TM
in the Sun Enterprise 220R server. This service manual also includes information
about diagnostics and maintenance of the system. This book is written for technicians,
system administrators, qualified service providers, and advanced computer system
end users who have experience troubleshooting and replacing server hardware.
This manual presents information in a modular format designed to answer the type
of questions that you might ask while servicing the Sun Enterprise 220R server.
Typically, the modules cover specific tasks for a service-related procedure for a
specific component.
Service providers who would like more general information about the system should
refer to the appropriate chapter or section in the Sun Enterprise 220R Server Owner's
Guide.
How This Book Is Organized
The chapters in this manual refer to a series of related service tasks. Using the table
of contents or the task list on the first page of each chapter, you can quickly find the
information you need to perform a specific task. The information modules for the
tasks are brief; however, they are interrelated and refer to other modules in the book.
For instance, the procedure "Replacing the Main Logic Board" is related to many
tasks covered by other modules. You must perform these requisite tasks before or
after replacing the main logic board.
This book is divided into six chapters and appendixes, as described below.
