Static electricity can damage electronic components. To avoid damage, keep option cards in
their static-protective package until you are ready to install them.
To reduce the possibility of electrostatic discharge, observe the following precautions:
Where possible ensure that antistatic protection is worn by the user (for example an
earthed antistatic wrist strap, an ankle or heel strap).
Handle the Option Card carefully, holding it by its edges or its rear panel.
Do not touch solder joints, pins, or exposed printed circuitry.
Do not leave the Option Card where others can handle and possibly damage it.
While the Option Card is still in its anti-static package, touch it to an unpainted
metal part of the system unit for at least two seconds. (This drains static electricity
from the package and from your body.)
Remove the Option Card from its package and install it directly into your base
chassis without setting it down. If it is necessary to set the Option Card down, place
it in its static-protective package.
Take additional care when handling components during cold weather, because
heating reduces indoor humidity and increases static electricity.
