Communications Statements
The following statement applies to this product. The statement for other products
intended for use with this product appears in their accompanying documentation.
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
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 A
Information Technology Equipment according to CISPR 22 / European Standard EN
55022. The limits for Class A equipment were derived for commercial and industrial
Communications ii

environments to provide reasonable protection against interference with licensed
communication equipment.
Attention: This is a Class A product. In a domestic environment this product may
cause radio interference in which case the user may be required to take adequate
measures.
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 is a Class A product based on the standard of the Voluntary Control Council for
Interference by Information Technology Equipment (VCCI). If this equipment is used
in a domestic environment, radio disturbance may arise. When such trouble occurs,
the user may be required to take corrective actions.
Electromagnetic Interference (EMI) Statement - Taiwan
The following is a summary of the EMI Taiwan statement above.
Warning: This is a Class A product. In a domestic environment this product may
cause radio interference in which case the user will be required to take adequate
measures.

Laser Safety Information
The optical drive in the RS/6000 7046 Model B50 is a laser product. The optical
drive has a label that identifies its classification. The label, located on the drive, is
shown below.
CLASS 1 LASER PRODUCT
LASER KLASSE 1
LUOKAN 1 LASERLAITE
APPAREIL A LASER DECLASSE1
IEC 825:1984 CENELEC EN 60 825:1991
The optical drive in the RS/6000 7046 Model B50 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 de ice. Do not attempt to operate the dri e
while it is disassembled. Do not attempt to open the co ers of the dri e as it
is not ser iceable 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 0.14 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.
