Epson Apex 20020 - Manual (Page 122)

Note
Pay specific attention to warnings in your option card
instructions. Some devices have delicate CMOS chips
that you should not touch.
When you handle the card, be careful not to touch any of
the contacts on the circuit board, especially the gold
connector pins. If you need to put the card down before
installing it, place the component side facing down on top
of the original packing. Keep the card’s original packing
materials in case you remove the card later.
3. Hold the card by the top comers so the connector pins are
pointing down and the components are facing the side of
the computer, as shown below.
4. Insert the card straight down into the slot. Once the
connector pins are in the connector slot, push down firmly
(but carefully) to fully insert the card. If the connector pins
do not seem to be going in smoothly, do not force the card;
pull it all the way out and try again. Be sure to keep the
card straight.
