Removing memory modules
WARNING: The DIMMs are hot to touch for some time after the server module 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 server module from the enclosure.
2. Open the server module.
3. Remove the cooling shroud.
4. If applicable, remove the following:
a. SSD/hard-drive backplane(s)
b. PCIe mezzanine card(s)
c. system board
5. If required, lift the latch on the PCIe mezzanine card support bracket to the open position.
6. Locate the memory module socket(s).
CAUTION: Handle each memory module only by the card edges, making sure not to touch
the middle of the memory module or metallic contacts.
7. Press down and out on the ejectors on each end of the socket until the memory module pops out of
the socket.
