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.

VCCI Statement
The following is a summary of the VCCI Japanese statement in the box above.
This equipment is in the Class 2 category (information equipment to be used in a
residential area or an adjacent area thereto) and conforms to the standards set by
the Voluntary Control Council For Interference by Data Processing Equipment and
Electronic Office Machines aimed at preventing radio interference in such residential
area.
When used near a radio or TV receiver, it may become the cause of radio
interference.
Read the instructions for correct handling.
