Installing Memory Modules

CAUTION: Only trained service technicians are authorized to remove the system cover and access any components inside the system. Before performing any procedure, see your Product Information Guide for complete information about safety precautions, working inside the computer, and protecting against electrostatic discharge.

1Turn off the system and attached peripherals, and disconnect the system from the electrical outlet and from the peripherals.

2Remove the system cover (see "Removing the System Cover" on page 66).

3Remove the processor airflow shroud (see "Removing the Processor Airflow Shroud" on page 70).

4Press the ejectors on the memory module connector down and out (see Figure 3-26) to allow the memory module to be inserted into the connector.

5Align the memory module's edge connector with the alignment key on the memory module connector, and insert the memory module into the connector (see Figure 3-26).

NOTICE: To avoid damage to the memory module, press the module straight down into the connector while applying equal force to each end of the module.

6Press down on the memory module with your thumbs until the module is firmly seated in the connector (see Figure 3-26).

When the memory module is properly seated, the ejectors on the memory module connector snap into the cutouts at each end of the memory module.

NOTICE: Never operate your system with the processor airflow shroud removed. Overheating of the system can develop quickly, resulting in shutdown of the system and loss of data.

7Replace the processor airflow shroud (see "Installing the Processor Airflow Shroud" on page 72).

8Replace the system cover (see "Installing the System Cover" on page 67).

9Reattach any peripherals you disconnected, then connect the system to the electrical outlet.

10Turn on the system and attached peripherals.
