Removing memory modules
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: 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 make sure 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. Remove the system cover.
3. Remove the cooling shroud.
4. Locate the appropriate memory-module sockets.
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.
