4. Remove the support bracket (see "Removing and installing the support
bracket" on page 38).
5. For easier access to the memory modules on the system board, rotate the
drive cage out of the computer until it locks into place. You might need to
disconnect the power cables from the drives before you rotate the cage all the
way.
Note: If you are installing memory modules on the microprocessor board for a
second microprocessor on the computer, it is not necessary to move the drive
cage.
6. If you are installing DIMMs for microprocessor 1, and you have installed a
second microprocessor on the computer, remove the microprocessor 2 air
baffle:
a. Lift up on the large end of the baffle until it releases.
b. Slide the baffle toward the front of the computer; then, lift the baffle out of
the computer.
7. Locate the DIMM connectors. Determine the connectors into which you will
install the DIMMs. See the notes on page 54 for the installation sequence.
8. Gently open the retaining clips on each end of the DIMM connectors you have
selected and, if necessary, remove any existing DIMMs.
9. Touch the static-protective package containing the new DIMM to any unpainted
metal surface on the computer. Then, remove the new DIMM from the
package.
10. Turn the DIMM so that the contacts align correctly with the connector.
11. Insert the DIMM into the connector. Firmly press the DIMM straight down into
the connector by applying pressure on both ends of the DIMM simultaneously.
The retaining clips snap into the locked position when the DIMM is firmly
seated in the connector. If there is a gap between the DIMM and the retaining
clips, the DIMM has not been correctly installed. Open the retaining clips,
remove the DIMM, and then reinsert it.
