Communications Statements
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.
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
Preface vii

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.
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.
Neither the provider nor the manufacturer can 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 not supplied by the manufacturer.
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.
Avis de conformité aux normes du ministère des Communications du
Canada
Cet appareil numérique de la classe A respecte toutes les exigences du Réglement
sur le matériel brouilleur du Canada.
Canadian Department of Communications Compliance Statement
This Class A digital apparatus meets the requirements of the Canadian
Interference–Causing Equipment Regulations.
VCCI Statement

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
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.
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

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 xi

DANGER
To prevent electrical shock hazard, disconnect the power cable 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.
CLASS1LASERPRODUCT
LASERKLASSE 1
LUOKAN1 LASERLAITE
APPAREIL A LASERDE CLASSE 1
IEC825:1984 CENELECEN 60825:1991
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
