CAUTION: Before you begin any of the procedures in this section,
follow the safety instructions on page 7.
Install only PCI cards in your computer. Before installing a card, make sure
that a slot is available for it.

computer and then unplug it from the network jack.

Pressing the power button when the computer is not connected to an
electrical outlet discharges residual electricity and can help prevent
system board damage.
