Removing Memory Modules
WARNING: The DIMMs are hot to touch for some time after the blade has been powered down. Allow time for the
DIMMs to cool before handling them. Handle the DIMMs by the card edges and avoid touching the DIMM
components.
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.
CAUTION: If you are permanently removing a processor, you must install a socket protective cap and a processor/
DIMM blank in the vacant socket to ensure proper system cooling. The processor/DIMM blank covers the vacant
sockets for the DIMMs and the processor.
1. Remove the blade from the enclosure.
2. Open the blade.
3. Remove the cooling shroud.
4. Locate the memory module socket(s).
