CE Notice (European Union)
Marking by the symbol indicates compliance of this computer to the EMC Directive and the Low Voltage Directive
of the European Union. Such marking is indicative that this system meets the following technical standards:
Set 1: For standard ITE with AC power supplies
• EN 55022 — "Information Technology Equipment — Radio Disturbance Characteristics — Limits and Methods of
Measurement."
• EN 55024 — "Information Technology Equipment - Immunity Characteristics - Limits and Methods of Measurement."
• EN 61000-3-2 — "Electromagnetic Compatibility (EMC) - Part 3: Limits - Section 2: Limits for Harmonic Current
Emissions (Equipment Input Current Up to and Including 16 A Per Phase)."
• EN 61000-3-3 — "Electromagnetic Compatibility (EMC) - Part 3: Limits - Section 3: Limitation of Voltage Fluctuations
and Flicker in Low-Voltage Supply Systems for Equipment With Rated Current Up to and Including 16 A."
• EN 60950 — "Safety of Information Technology Equipment."
For –48 volt-direct-current (VDC) powered systems, the following set of standards applies. See the "Declaration of Conformity"
to determine whether a particular system meets EN 50082-1 or EN 50082-2 requirements.
Set 2: For –48-VDC powered systems
• EN 55022 — "Information Technology Equipment — Radio Disturbance Characteristics — Limits and Methods of
Measurement."
• EN 50082-1 — "Electromagnetic Compatibility - Generic Immunity Standard - Part 1: Residential, Commercial and Light
Industry."
• EN 50082-2 — "Electromagnetic Compatibility - Generic Immunity Standard - Part 2: Industrial Environment."
• EN 60950 — "Safety of Information Technology Equipment."
NOTE: EN 55022 emissions requirements provide for two classifications:
• Class A is for typical commercial areas.
• Class B is for typical domestic areas.
To determine which classification applies to your computer, examine the FCC or ICES information on the regulatory label on the
back, side, or bottom panel of the computer. If the FCC or ICES information on the label indicates a Class A rating, the following
Class A warning applies to your computer:
RF INTERFERENCE WARNING: This is a Class A product. In a domestic environment this product may cause radio
frequency (RF) interference, in which case the user may be required to take adequate measures.
If the FCC or ICES information on the label indicates a Class B rating, the following Class B statement applies to your computer:
This device is classified for use in a typical Class B domestic environment.
Simplified Chinese Class A Warning Notice (China Only)
On Class A systems, the following warning will appear near the regulatory label:
Warning: 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.
