Installation Instructions
CAUTION
Follow these guidelines to meet safety and regulatory requirements when installing this board
assembly.
Read and adhere to all of these instructions and the instructions supplied with the chassis and
associated modules. If the instructions for the chassis are inconsistent with these instructions or
the instructions for associated modules, contact the supplier’s technical support to find out how
you can ensure that your computer meets safety and regulatory requirements. If you do not follow
these instructions and the instructions provided by chassis and module suppliers, you increase
safety risk and the possibility of noncompliance with regional laws and regulations.
Ensure Electromagnetic Compatibility (EMC)
Before computer integration, make sure that the power supply and other modules have passed
EMC testing using a board with a processor from the same family and operating at the same (or
higher) speed as the processor on this desktop board.
In the installation instructions for the host chassis, power supply, and other modules pay close
attention to the following:
• Certifications
• External I/O cable shielding and filtering
• Mounting, grounding, and bonding requirements
• Keying connectors when mating the wrong 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 desktop boards now have PTCs on all
external ports that provide DC power externally.
