3. Open the plastic ejector levers at each end of the DIMM socket on the memory board (Figure
23, A).
4. Orient the DIMM so that the notch in the bottom edge of the DIMM aligns with the keyed socket
on the memory board.
5. Insert the bottom edge of the DIMM into the socket and press down firmly on the DIMM until it
seats correctly. The plastic ejector levers should snap into place when the DIMM is seated.
6. Make sure that the plastic ejector levers on the socket ends are fully closed.
7. Reinstall the memory board (page 36).
