Installing a memory module
Attention: Do not open your server or attempt any repair before reading and understanding “Safety information”
on page iii and “Guidelines” on page 39.
This topic provides instructions on how to install a memory module.
Before you begin, print all the related instructions or ensure that you can view the PDF version on another
computer for reference.
Notes:
1. To optimize system performance, make sure that you consider and follow the memory module
installation rules when performing the operation. See “Memory module installation rules” on page 45.
2. Use any documentation that comes with the memory module and follow those instructions in addition to
the instructions in this topic.
To install a memory module, do the following:
1. Remove all media from the drives and turn off all attached devices and the server. Then, disconnect all
power cords from electrical outlets and disconnect all cables that are connected to the server.
2. Remove the server cover. See “Removing the server cover” on page 41.
3. Lay the server on its side for easier operation.
4. Locate the memory slots on the system board. See “Locating parts on the system board” on page 17.
5. Remove any parts or disconnect any cables that might prevent your access to the memory slots.
Depending on your server model, you might need to remove the PCI Express x16 card for easier access
to the memory slots. See “Installing or replacing a PCI card” on page 62
6. Open the retaining clips of the appropriate memory slot. See “Memory module installation rules” on
page 45 for the installation sequence information.

the outside of the server. Then, take the new memory module out of the package.
Note: Carefully handle the memory module by its edges.
