Safety Precaution - Static Electricity
Follow these simple precautions to protect yourself from harm and the products from
damage.
! To avoid electrical shock, always disconnect the power from the PC chassis
before working on it. Don't touch any components on the CPU card or other
cards while the PC is on.
! Disconnect power before making any configuration changes. The sudden rush
of power while connecting a jumper or installing a card may damage sensitive
electronic components.
