CAUTION: The memory modules are hot to the touch for some time after the system has been powered down. Allow time for the memory modules to cool before handling them. Handle the memory modules by the card edges and avoid touching the components on the memory module.

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

2Open the system. See "Opening the System" on page 65.

3Remove the PEM. See "Removing the PEM or PEM Shell" on page 73.

4Remove the cooling shroud assembly:

–If you are removing memory modules on the system board, see "Removing the Cooling Shroud Assembly" on page 69.

–If you are removing memory modules on the PEM, see Figure 3-9.

5Locate the memory module sockets. See Figure 6-1.

6Press down and out on the ejectors on each end of the socket until the memory module pops out of the socket. See Figure 3-19.

Handle each memory module only on either card edge, ensuring not to touch the middle of the memory module.

7Replace the cooling shroud assembly:

–If you are removing memory modules on the system board, see "Replacing the Cooling Shroud Assembly" on page 70.

–If you are removing memory modules on the PEM, see Figure 3-9.

8Replace the PEM. See "Replacing the PEM or PEM Shell" on page 76.

9Close the system. See "Closing the System" on page 66.

Processors

Your system supports either two or four processors. You can upgrade processors to take advantage of future options in speed and functionality. Each processor and its associated internal cache memory are contained in a land grid array (LGA) package that is installed in a socket on the system board or processor expansion module.

NOTICE: All processors must have the same frequency and core voltage.
