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 are shipped with your product.
CAUTION:
To ensure proper 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.
