memory socket that is not occupied. Remove memory module blanks only if you
intend to install memory modules in those sockets.
Procedure
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.

Do not apply pressure at the center of the memory module; apply pressure
at both ends of the memory module evenly.

The memory module socket has an alignment key that enables you to install the
memory module in the socket in only one orientation.
