Ensure Host Computer and Accessory Module Certifications
Make sure that the host computer, any added subassembly (such as a board or drive assembly,
including 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 host
computer 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, may 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 Amp current limiting circuit or a maximum
5 Amp fuse or positive temperature coefficient (PTC) resistor. This Intel server board has 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 Amp current limiting circuit or a maximum approved
5 Amp fuse or positive temperature coefficient (PTC) resistor. This server board has PTCs on all
external ports that provide DC power externally.
Prevent Power Supply Overload
Do not overload the power supply output. To avoid overloading the power supply, make sure that
the calculated total current load of all the modules within the computer is less than the maximum
output current rating of the power supply. If you do not do this, the power supply may overheat,
catch fire, or damage the insulation that separates hazardous AC line circuitry from low voltage
user accessible circuitry and result in a shock hazard. If the load drawn by a module cannot be
determined by the markings and instructions supplied with the module, contact the module
supplier’s technical support.
