About Service Functions (SY44-5902-03)
This book provides basic information about iSeries functions that are commonly
used by field hardware service representatives. It provides enough detail for the
hardware service representative to gather information about hardware problems
while under the direction of the next level of support.
The book is meant to assist the hardware service representative in gathering
information about commonly encountered field problems. It does not cover all
service functions available on the iSeries.

Who should read this book

This book is intended for trained iSeries hardware service representatives and
service providers who act as the primary level of field hardware service support
(as opposed to system operators) to help solve and diagnose hardware problems.
Before using this book, you should know how to service (analyze, isolate, report,
and resolve problems, and verify fixes using the iSeries maintenance package) the
iSeries hardware. Youmust also know how to safely work with electrical
components.
Attention: Some service tools described in this book can be used to change or
erase data, programs, or other objects on the iSeries system. This damage can occur
with the misuse of service tools or with inappropriate security in effect.

Conventions and terminology used in this book

Prerequisite and related information

Use the iSeries Information Center as your starting point for looking up iSeries
technical information. You can access the Information Center from the following
Web site::

The iSeries Information Center contains advisors and important topics such as CL
commands, system application programming interfaces (APIs), logical partitions,
clustering, Java, TCP/IP, Web serving, and secured networks. It also includes links
to related IBM Redbooks and Internet links to other IBM Web sites such as the
Technical Studio and the IBM home page.
