WARNING: Allow the memory modules to cool after you power off the system. Handle the memory modules by the card edges and avoid touching the components or metallic contacts on the memory module. Steps 1. Push the ejectors outward on both ends of the memory module socket to release the memory module from the socket. 2. Lift and remove the memory module from the system. CAUTION: Handle memory modules only by the card edges, ensuring not to touch the middle of the memory module or metallic contacts. NOTE: If you are removing the memory module permanently, install a memory module blank. The procedure to install a memory module blank is similar to that of the memory module. Figure 73. Removing a memory module Next steps Replace the memory module. Installing a memory module Prerequisites 1. Follow the safety guidelines listed in Safety instructions. 2. Power off the system and all attached peripherals. 3. Disconnect the system from the electrical outlet, and disconnect the peripherals. 4. Ensure that all internal cables are routed correctly and connected, and no tools or extra parts are left inside the system. 5. Open the drive bays, remove all drives, and then close the drive bays. 6. Remove the power supply units. 7. Remove the system from the rack and place it on an ESD work bench. For more information, see the Rail Installation Guide available at www.dell.com/poweredgemanuals. 8. Remove the system cover. 9. Remove the air shroud. Locate the appropriate memory module socket. NOTE: The procedure to remove a memory module blank is similar to the procedure to remove a memory module. Retain the removed memory module blank for future use. Steps 1. Open the ejectors on the memory module socket outward to allow the memory module to be inserted into the socket. 2. Align the edge connector of the memory module with the alignment key of the memory module socket, and insert the memory module in the socket. CAUTION: Handle each memory module only by the card edges, ensuring not to touch the middle of the memory module or metallic contacts. Installing and removing system components 97
