Ensure Electromagnetic Compatibility (Emc); Ensure Chassis And Accessory Module Certifications - Intel BI440ZX Product Manual

Ensure Electromagnetic Compatibility (EMC)

Before computer integration, make sure that the power supply and other modules have passed
EMC testing using a motherboard with a processor from the same family and operating at the same
(or higher) speed as the processor on this motherboard.
In the installation instructions for the host chassis, power supply, and other modules pay close
attention to the following:
x
Certifications
x
External I/O cable shielding and filtering
x
Mounting, grounding, and bonding requirements
x
Keying connectors when mismating of connectors could be hazardous
If the power supply and other modules have not passed applicable EMC testing before integration,
EMC testing must be conducted on a representative sample of the newly completed computer.

Ensure Chassis and Accessory Module Certifications

Make sure that the chassis, any added subassembly, such as a board or drive assembly, and internal
or external wiring, are certified for the region(s) where the end-product will be used. Marks on the
product are proof of certification. Certification marks are as follows:
In Europe
The CE marking signifies compliance with all relevant European requirements. If the chassis does
not bear the CE marking, obtain a supplier's Declaration of Conformity to the appropriate
standards required by the European EMC Directive and Low Voltage Directive. Other directives,
such as the Machinery and Telecommunications Directives, might also apply depending on the
type of product. No regulatory assessment is necessary for low voltage DC wiring used internally
or wiring used externally when provided with appropriate overcurrent protection. Appropriate
protection is provided by a maximum 8-A current limiting circuit or a maximum 5-A fuse or
positive temperature coefficient (PTC) resistor. All Intel motherboards now have PTCs on all
external ports that provide DC power externally.
In the United States
A certification mark by a Nationally Recognized Testing Laboratory (NRTL) such as UL, CSA, or
ETL signifies compliance with safety requirements. External wiring must be UL Listed and
suitable for the intended use. Internal wiring must be UL Listed or Recognized and rated for
applicable voltages and temperatures. The FCC mark (Class A for commercial or industrial only
or Class B for residential) signifies compliance with electromagnetic interference requirements.
In Canada
A nationally recognized certification mark such as CSA or cUL signifies compliance with safety
requirements. No regulatory assessment is necessary for low voltage DC wiring used internally or
wiring used externally when provided with appropriate overcurrent protection. Appropriate
protection is provided by a maximum 8-A current limiting circuit or a maximum 5-A fuse or
positive temperature coefficient (PTC) resistor. All Intel motherboards now have PTCs on all
external ports that provide DC power externally.
