To add memory, perform the following steps.

1. Remove the computer cover.

2. Determine the memory module sockets in which you will install modules or replace existing modules.

3. Rotate the green MEC cover up to lift the MEC up from the system board, and remove the MEC from the system. See "Removing and

Installing a Memory Expansion Card."

4. Repeatstep3fortheotherMEC.

5. Install or replace the memory modules as necessary to reach the desired memory total.

To install a memory module, perform the following steps:

a. Locate the plastic securing clips at each end of the socket (see Figure 7). Press the clips outward until they snap open.

b. Press the memory module straight into the slot running down the center of the socket until the securing tabs snap into place around the

ends of the memory module.

To remove a memory module, press the securing clips outward simultaneously until the module disengages from the socket (see

Figure 8). It should pop out slightly.

at each end of the module.

NOTICE: Do not leave empty sockets between RIMMs. After you install the last RIMM, insert a C-RIMM in socket RIMM1_A or

RIMM4_B, whichever is the lowest-numbered empty socket, on each MEC.
