Installing a memory module
Attention:
Do not open your server or attempt any repair before reading and understanding the Safety Information and the
Warranty and Support Information on the ThinkServer Documentation DVD that came with your product, and
“Guidelines” on page 21. To obtain a copy of the publications, go to:
This section provides instructions on how to install a memory module.
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 23.
3. Locate the appropriate memory slot on the system board into which you will install the memory module.
To optimize system performance, follow the related memory module installation rules and install the
memory module into a memory slot starting with the memory module farthest from the microprocessor.
See “Memory module installation rules” on page 29.
