Unpack the option card and adjust any switches or
jumpers on it, if necessary. (Check the option card
instructions.) When you handle the card, be careful not
to touch any of the components on the circuit board or
the gold-edged connectors. If you need to set it down
before you install it, place it gently on top of its original
packing material with the component side facing up.
Keep the packing materials in case you remove the card
later.
Grip the card firmly by the top comers and make sure the
connectors point down, as shown below.
Insert the card into the slot, guiding it straight down.
Once the connectors reach the slot, push the card
downward firmly (but carefully) to insert it fully. You
should feel the card fit into place.
If the card does not go in smoothly, do not force it; pull
it all the way out and try again, keeping it straight as you
insert it. Examine the card to verify that it is fully seated
in the slot along the length of the connector.
