2. Follow the procedure listed in Before working inside your system on page 28.CAUTION: To prevent data loss and potential damage to your system, ensure that your system, LEDs onsystem, LEDs on NVDIMM-N and LEDs on NVDIMM-N battery are turned off before removing the NVDIMM-Nbattery.3. Remove the air shroud.WARNING: Allow the memory modules to cool after you power off the system. Handle the memory modules bythe 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 thatis not occupied. Remove memory module blanks only if you intend to install memory modules in those sockets.Steps1. Locate the appropriate memory module socket.CAUTION: Handle each memory module only by the card edges, ensuring not to touch the middle of thememory 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.Figure 63. Removing a memory moduleNext steps1. Install the memory module.2. If you are removing the memory module permanently, install a memory module blank. The procedure to install a memorymodule blank is similar to that of the memory module.Installing a memory moduleThe procedure for installing a DIMM module and an NVDIMM-N module is identical.PrerequisitesFollow the safety guidelines listed in Safety instructions on page 27.CAUTION: Ensure that you install the NVDIMM-N battery if you are using NVDIMM-N.CAUTION: To prevent data loss and potential damage to your system, ensure that your system, LEDs on system,LEDs on NVDIMM-N and LEDs on NVDIMM-N battery are turned off before installing the NVDIMM-N battery.CAUTION: To ensure proper system cooling, memory module blanks must be installed in any memory socket thatis not occupied. Remove memory module blanks only if you intend to install memory modules in those sockets.Steps1. Locate the appropriate memory module socket.78 Installing and removing system components
