Communications Statements
The following statement applies to this product. The statement for other products
intended for use with this product appears in their accompanying manuals.
If Feature Codes 2743, 3615, 6218, 8130 or 8134 are NOT installed, this system
complies with the limits for a Class B digital device, pursuant to Part 15 of the FCC
Rules.
Federal Communications Commission (FCC) Statement
Note: The IBM RS/6000 7024 E Series Server has been tested and found to
comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC
Rules. These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to try
to correct the interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
Consult an authorized dealer or service representative for help.
Properly shielded and grounded cables and connectors must be used in order to
meet FCC emission limits. Proper cables and connectors are available from
authorized dealers. Neither the provider nor the manufacturer are responsible for
any radio or television interference caused by using other than recommended cables
and connectors or by unauthorized changes or modifications to this equipment.
Unauthorized changes or modifications could void the user's authority to operate the
equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions: (1) this device may not cause harmful interference, and (2)
this device must accept any interference received, including interference that may
cause undesired operation.

European Union (EU) Statement
This product is in conformity with the protection requirements of EU Council Directive
89/336/EEC on the approximation of the laws of the Member States relating to
electromagnetic compatibility. The manufacturer cannot accept responsibility for any
failure to satisfy the protection requirements resulting from a non-recommended
modification of the product, including the fitting of option cards supplied by third
parties. Consult with your dealer or sales representative for details on your specific
hardware.
This product has been tested and found to comply with the limits for Class B
Information Technology Equipment according to CISPR 22 / European Standard EN
55022. The limits for Class B equipment were derived for typical residential
environments to provide reasonable protection against interference with licensed
communication devices.
International Electrotechnical Commission (IEC) Statement
This product has been designed and built to comply with IEC Standard 950.
United Kingdom Telecommunications Safety Requirements
This equipment is manufactured to the International Safety Standard EN60950 and
as such is approved in the UK under the General Approval Number
NS/G/1234/J/100003 for indirect connection to the public telecommunication network.
The network adapter interfaces housed within this equipment are approved
separately, each one having its own independent approval number. These interface
adapters, supplied by the manufacturer, do not use or contain excessive voltages.
An excessive voltage is one which exceeds 70.7 V peak ac or 120 V dc. They
interface with this equipment using Safe Extra Low Voltages only. In order to
maintain the separate (independent) approval of the manufacturer's adapters, it is
essential that other optional cards, not supplied by the manufacturer, do not use
main voltages or any other excessive voltages. Seek advice from a competent
engineer before installing other adapters not supplied by the manufacturer.

If Feature Codes 2743, 3615, 6218, 8130 or 8134 are installed, this system complies
with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules.
Federal Communications Commission (FCC) Statement
Note: This equipment has been tested and found to comply with the limits for a
Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference when the
equipment is operated in a commercial environment. This equipment generates,
uses, and can radiate radio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to cause
harmful interference in which case the user will be required to correct the
interference at his own expense.
Properly shielded and grounded cables and connectors must be used in order to
meet FCC emission limits. Neither the provider nor the manufacturer are responsible
for any radio or television interference caused by using other than recommended
cables and connectors or by unauthorized changes or modifications to this

Safety Notices
A danger notice indicates the presence of a hazard that has the potential of causing
death or serious personal injury.
A caution notice indicates the presence of a hazard that has the potential of causing
moderate or minor personal injury.
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 communication lines.
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.
Preface xv

DANGER
To prevent electrical shock hazard, disconnect the power cable from
the electrical outlet before relocating the system.

that identifies its classification. The label, located on the drive, is shown below.
CLASS1LASERPRODUCT
LASERKLASSE1
LUOKAN1LASERLAITE
APPAREIL A LASERDECLASSE1
IEC825:1984 CENELECEN60825:1991
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
