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 desktop boards now have PTCs on all
external ports that provide DC power externally.
Prevent Power Supply Overload
Unless the power supply has inherent overcurrent protection, 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 output current rating of the power supply. If
you do not do this, the power supply could overheat, catch fire, or damage the insulation that
separates hazardous AC line circuitry from low-voltage user accessible circuitry. 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.
Place Battery Marking on the Computer
There is insufficient space on this board to provide instructions for replacing and disposing of the
battery. The following warning must be placed permanently and legibly on the chassis as near as
possible to the battery.
WARNINGS
Danger of explosion if battery is incorrectly replaced.
Replace with only the same or equivalent type recommended by the manufacturer. Dispose of
used batteries according to the manufacturer’s instructions.
Use Only for Intended Applications
This board was evaluated for use in computers that will be installed in offices, homes, schools,
computer rooms, and similar locations. The suitability of this product for other applications, (such
as medical, industrial, alarm systems, and test equipment) might require further evaluation.
