2. If you are removing the memory module permanently, install a memory module blank. The procedure to install a memory module blank is similar to that of the memory module. NOTE: When operating your system with single processor, install DIMM blanks in CPU2 memory sockets. Installing a memory module Prerequisites Follow the safety guidelines listed in Safety instructions on page 41. CAUTION: To ensure proper system cooling, memory module blanks must be installed in any memory socket that is not occupied. Remove memory module blanks only if you intend to install memory modules in those sockets. NOTE: You must follow the thermal restriction while using DIMM blank. For information about thermal restriction, see Thermal restrictions matrix . Steps 1. Locate the appropriate memory module socket. CAUTION: Handle each memory module only by the card edges, ensuring not to touch the middle of the memory module or metallic contacts. CAUTION: To prevent damage to the memory module or the memory module socket during installation, do not bend or flex the memory module. You must insert both ends of the memory module simultaneously. 2. Open the ejectors on the memory module socket to allow the memory module to be inserted into the socket. 3. Align the edge connector of the memory module with the alignment key of the memory module socket, and insert the memory module in the socket. CAUTION: Do not apply pressure at the center of the memory module; apply pressure at both ends of the memory module evenly. NOTE: The memory module socket has an alignment key that enables you to install the memory module in the socket in only one orientation 4. Press the memory module with your thumbs until the socket levers firmly click into place. Figure 50. Installing a memory module Next steps 1.
