Removing a DIMM
To remove a DIMM, complete the following steps:
1. Read the safety information that begins on page vii and “Installation guidelines”
on page 73.
2. Turn off the computer and all attached devices; then, disconnect all external
cables and power cords.
3. Remove the side cover (see “Removing the side cover” on page 75).
4. Remove the hard disk drive bracket, if one is installed (see “Removing the hard
disk drive bracket” on page 95).
5. For easier access to the memory modules on the system board, it might be
easier to remove the drive cage from the computer (see Figure 23):
a. Loosen the thumbscrew at the rear of the drive cage.
b. Slide the drive cage to the rear to disengage it from the upper clips and lift
the cage out of the computer.
Note: You might have to disconnect the power cables from the drives
before you lift the cage all the way out of the computer.
6. Disconnect any cables that impede access to the DIMMs.
7. Locate the DIMM connector with the DIMM to be replaced (see “System-board
option connectors” on page 6 for DIMM slot locations).
Attention: To avoid breaking the retaining clips or damaging the DIMM
connectors, open and close the clips gently.
