164 Appendix C
7 Locate the vertical connector for the RAM card near the right side of the computer.
The connector is approximately 2 inches in from the right side of the case.
The RAM card’s design allows for one card to be connected to the socket on
top of a card that is installed on the computer’s main logic board. Therefore,
your computer may have a RAM card already installed; if so, you will still
see the vertical connector on the top of the installed RAM card. (See the
illustration at the beginning of these instructions for reference.)
The area around the RAM card’s vertical connector may be partially obscured
if your computer has a card installed in the expansion card slot (the expansion
card slot is not used for a RAM card).
RAM card fits into
vertical connector.
