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 73.
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:
• To optimize system performance, ensure that you consider and follow the memory module installation
rules when performing the operation. See “Memory module installation rules” on page 81.
• 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. If the server is installed in a rack cabinet, remove the server from the rack cabinet and place it on a flat,
clean, and static-protective surface. See the Rack Installation Instructions that comes with the server.
3. Remove the server cover. See “Removing the server cover” on page 75.
