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.

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.

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 IBM 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.

Data Integrity and Verification
IBM 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 the IBM support websites for updated
information and fixes applicable to the system and related software.

About This Book
This book provides maintenance information that is specific to the Eserver pSeries 650, 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 Eserver pSeries 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.
Accessing Information
Documentation for the IBM Eserver pSeries is available online. Visit the IBM Eserver pSeries
Information Center at http://publib16.boulder.ibm.com/pseries/en_US/infocenter/base.
