4. To install a new DIMM, hold the module only by the edges as you
remove it from its anti–static package.
5. Position the DIMM so that the small notches in the bottom edge of
the DIMM align with the notches in the DIMM socket on the CPU
card. The retaining latch should be fully disengaged when
attempting to install a DIMM.
6. Press down firmly and uniformly on the DIMM to seat it in the
socket. The latch should engage in the DIMM locking slot to secure
the part in place.
7. Reinstall the CPU card if necessary (Refer to “Adding/Removing
CPU and Add-in Cards” on page 4-4 for complete instructions), and
reinstall the top access cover.
