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 outward 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 54. Installing a memory module on the system board or PEM Next steps 1.
