The system must be plugged in (see step 2 on page 68) for this to work.
Use an anti-static bracelet and handle memory modules by the non-
metallic edges only.
1.
To insert a DIMM module, hold the module with one hand at each end with
the contacts down and the chip side of the DIMM toward the front of the
computer.
Notice that there are two notches in the contact edge of the DIMM module.
2.
Lower the DIMM squarely into the slot so that the notches line up with the
raised key areas of the DIMM socket.
