Memory DIMM Removal To remove the memory DIMMs, do the following: 1. Shut down the system as described in "Stopping the System" on page 25. 2. Place the system into the service position as described in "Placing the Model 275 into the Service and Operating Position" on page 26. 3. Disconnect the power source from the system. Note: This system may be equipped with a second power supply. Before continuing with this procedure, ensure that the power source to the system has been completely disconnected. 4. Remove the service access cover as described in "Service Access Cover Removal" on page 28. 5. Remove the fan tray assembly as described in "Removing the Fan Tray Assembly" on page 35. 6. If necessary to access DIMM positions on the system backplane, remove the power supply filler and the power supply as described in "Power Supply Removal" on page 38. 7. If necessary to access DIMMs on the system backplane, remove the service processor assembly as described in "Service Processor Assembly" on page 57. 8. Before handling any card, board, or memory DIMM, touch any metal surface of the chassis with one hand to minimize static electricity discharge. Refer to "Handling Static-Sensitive Devices" on page 24. 9. Determine which memory DIMM you want to remove. See the illustration in "Memory DIMM Installation and Replacement" on page 54. 10. Remove the memory DIMM by pushing the tabs out and then down. The tabs' camming action forces the memory DIMM out of the connector. Attention: To prevent damage to the memory DIMM and the memory DIMM connectors, open or close the retention latches at the same time. 11. Pull the memory DIMM out of the connector as shown in the following illustration. 2 1 1 1 Connector Tabs (unlocked position) 2 Memory DIMM 56 IntelliStation POWER 9114 Model 275 Installation Guide
