Removing a memory module
Follow the below procedure for removing a DIMM module:
Prerequisites
1 Follow the safety guidelines listed in Safety instructions.
2 Follow the procedure listed in Before working inside your system.
3 If applicable, remove the air shroud.
WARNING
: Allow the memory modules to cool after you power o the system. Handle the memory modules by the card edges
and avoid touching the components or metallic contacts on the memory module.
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.
Steps
1 Locate the appropriate memory module socket.
CAUTION
: Handle each memory module only by the card edges, ensuring not to touch the middle of the memory module or
metallic contacts.
2 Push the ejectors outward on both ends of the memory module socket to release the memory module from the socket.
3 Lift and remove the memory module from the system.
