CAUTION: Many repairs may only be done by a certified service technician. You should only perform
troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or
telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by your
warranty. Read and follow the safety instructions that came with the product.
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.
