Precautions
This section contains safety information and advice on how to avoid damage to the
motherboard.
1.2.1
Ensuring safety
The motherboard is powered from an ATX power supply unit within the ATX enclosure.
Warning
To avoid a safety hazard:
•
To use the motherboard in its supplied plastic enclosure, only use the supplied 12V power
supply unit to provide power to the connector on the enclosure.
•
To use an ATX power supply, remove the top cover from the enclosure and use an ATX
power supply to provide power to the motherboard ATX connector. This option is
typically used to provide access to the PCI-Express sites.
1.2.2
Preventing damage
The motherboard is intended for use in a laboratory or engineering development environment.
If removed from its enclosure, the board becomes more sensitive to electrostatic discharges and
generates increased electromagnetic emissions. Removing the board from the enclosure also
results in flexing that fractures the printed-circuit board connections to the components.
Caution
To avoid damage, observe the following precautions:
•
Never subject the board to high electrostatic potentials.
•
Always wear a grounding strap when touching the board in or away from its enclosure.
•
Avoid touching the component pins or any other metallic element.
•
Always power down the board when connecting daughterboards, memory expansion
boards, or making external connections.
•
Do not remove the board from its enclosure.
Caution
Do not use near equipment that is:
•
Sensitive to electromagnetic emissions, for example medical equipment.
•
A transmitter of electromagnetic emissions.
