Electrical Safety
Observe the following safety instructions any time you are connecting or disconnecting
devices attached to the workstation.
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.
Before installing or removing signal cables, ensure that the power cables for
the system unit and all attached devices are unplugged.
When adding or removing any additional devices to or from the system,
ensure that the power cables for those devices are unplugged before the
signal cables are connected. If possible, disconnect all power cables from the
existing system before you add a device.
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.
D05
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.

Laser Safety Information
The optical drive in this system unit is a laser product. The optical drive has a label that
identifies its classification. The label, located on the drive, is shown below.
xii Service Guide

The optical drive in this system unit is certified in the U.S. to conform to the
requirements of the Department of Health and Human Services 21 Code of Federal
Regulations (DHHS 21 CFR) Subchapter J for Class 1 laser products. Elsewhere, the
drive is certified to conform to the requirements of the International Electrotechnical
Commission (IEC) 825 (1st edition 1984) and CENELEC EN 60 825:1991 for Class 1
laser products.
CAUTION:
A class 3 laser is contained in the device. Do not attempt to operate the drive
while it is disassembled. Do not attempt to open the covers of the drive as it is
not serviceable and is to be replaced as a unit.
Class 1 laser products are not considered to be hazardous. The optical drive contains
internally a Class 3B gallium-arsenide laser that is nominally 30 milliwatts at 830
nanometers. The design incorporates a combination of enclosures, electronics, and
redundant interlocks such that there is no exposure to laser radiation above a Class 1
level during normal operation, user maintenance, or servicing conditions.

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 RS/6000 44P Series
Model 270, as well as to adapters and attached devices that do not have their own
service information. In this book, the RS/6000 44P Series Model 270 is hereafter
referred to as the ″system″or the ″server.″
This book also contains maintenance analysis procedures (MAPs) that are not common
to other systems. MAPs that are common to all systems are contained in the RS/6000
and Eserver pSeries Diagnostics Information for Multiple Bus Systems.
This book is used by the service technician to repair system failures. This book
assumes that the service technician has had training on the system unit.
ISO 9000
ISO 9000 registered quality systems were used in the development and manufacturing
of this product.
Online Publications
RS/6000 publications are available online. To access the online books, visit our Web
site at: http://www.rs6000.ibm.com/resource/hardware_docs/
