To install a DIMM, complete the following steps:
1. Read the safety information that begins on page v and "Installation guidelines"
on page 29.
2. Turn off the computer and all attached devices (see "Turning off the computer"
on page 18); then, disconnect all power cords and external cables.
3. Remove the side cover (see "Removing the side cover" on page 35).
4. For easier access, lay the computer on its side.
5. Lift the power supply handle and rotate the power supply handle out of the
chassis.
6. Press and hold the drive-cage release lever; then, rotate the drive cage
completely out of the chassis until the retaining tab on top of the cage locks
into place.
7. Locate the DIMM connectors on the system board. Determine the connectors
into which you will install the DIMMs. DIMM 1 and DIMM 3 must be the first
installed pair, followed by DIMM 5 and DIMM 7, DIMM 2 and DIMM 4, and
DIMM 6 and DIMM 8.
8. Gently open the retaining clips and, if necessary, remove any existing DIMM.
Attention: To avoid breaking the retaining clips or damaging the DIMM
connectors, open and close the clips gently.
9. Touch the static-protective package that contains the DIMM to any unpainted
metal surface on the computer. Then, remove the new DIMM from the
package.
10. Gently open the retaining clip on each end of the DIMM slot. Turn the DIMM
so that the pins align correctly with the connector.
