Field Replaceable Units (FRUs) FRU Removal and Replacement Memory DIMMs The J5000 workstation has eight slots for memory DIMMs, while the J7000 has sixteen slots. As you face the workstation, the memory DIMM slots are located on the system board on the left side of the workstation. Removing a Memory DIMM To remove a DIMM, do the following: 1. Remove the top panel and the left side panel of the workstation. 2. If this is a J7000 workstation, remove the four T-15 Torx screws from the front air divider on the left side of the workstation, and then remove the front air divider. 3. Locate the DIMM slots on the system board on the left side of the workstation. 4. Press down on the left and right DIMM extractor handles to release the DIMM memory from the slot. 5. Carefully lift out the DIMM and place it in an antistatic bag for storage. Replacing a Memory DIMM To replace a DIMM, do the following: 1. If you will install additional DIMMs in the workstation, use the Boot Console Handler procedure in "Displaying the Current Monitor Configuration" on page 130 in Chapter 5 to determine the current memory configuration of the workstation. 2. Remove the top panel and the left side panel of the workstation. 3. If this is a J7000 workstation, remove the four screws from the front air divider on the left side of the workstation, and then remove the front air divider. 4. Locate the DIMM slots on the system board on the left side of the workstation. 5. Familiarize yourself with the order in which DIMMs must be inserted. This information is on the "Memory Installation Sequence" label on the floor of the workstation's left side. For more details, see the configuration section titled "Memory" on page 37 in Chapter 2. NOTE The J7000 workstation requires that DIMMs are installed in pairs of equal memory size. In contrast, individual DIMMs of different memory sizes (namely, 256 and 512 MB) may be installed in the J5000 workstation. 6. Angle the left and right DIMM extractor handles on the DIMM slot outward. 7. Position the DIMM correctly to allow insertion into the DIMM slot. 8. Press firmly and evenly on the DIMM until it is fully seated in the slot. The extractor handles will close inward as the DIMM is inserted. 9. If this is a J7000 workstation, replace the front air divider and the four T-15 Torx screws securing the rear air divider. Chapter 4 99
