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), is 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:
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.
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.
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.
