Removing Memory Modules
WARNING: The memory modules are hot to the touch for some time after the system has been powered down.
Allow time for 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: 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).
