2. Follow the procedure listed in Before working inside your system.

WARNING: The memory modules are hot to touch for some time after the system has been
powered down. Allow the memory modules to cool before handling them. Handle the memory
modules by the card edges and avoid touching the components or metallic contacts on the
memory module.
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.
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.
2. If a memory module or a memory-module blank is installed in the socket, remove it.
NOTE: Retain the removed memory-module blanks for future use.
CAUTION: To prevent damage to the memory module or the memory-module socket during
installation, do not bend or flex the memory module; insert both ends of the memory module
simultaneously.
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.
NOTE: The memory-module socket has an alignment key that allows you to install the memory
module in the socket in only one orientation.
CAUTION: Do not apply pressure at the center of the memory module; apply pressure at both
ends of the memory module evenly.
4. Press the memory module with your thumbs until the socket levers firmly click into place.
