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.
1. Turn off the system, including any attached peripherals, and disconnect the system from the
electrical outlet and peripherals.
2. Open the system.
3. Remove the cooling shroud.
4. Locate the appropriate memory-module socket(s).
5. To release the memory-module blank from the socket, simultaneously press the ejectors on both
ends of the memory module socket.
CAUTION: Handle each memory module only by the card edges, making sure not to touch
the middle of the memory module or metallic contacts. To avoid damaging the memory
module, handle only one memory module at a time.
