1 Slot at JDIM11 Slot at JDIM10 Slot at JDIM01 Slot at JDIM00 Figure 16. DIMM slot location There are four DIMM slots, two for each Cell/B.E. companion chip. If this is the first pair of DIMMs you are installing, use slots 00 and 11. Slots 00 and 11 are the two outer slots as shown in Figure 16. For a second pair of DIMMs, use the remaining slots 01 and 10. 5. Remove the DIMM fillers from the slots where you want to insert the DIMMs. Retain the DIMM fillers. You need them if you remove any DIMMs from the blade server as they are an important part of the blade server cooling system. 6. Place the DIMM in the slot, contact side down. Check the orientation of the module. The central locating pin in the slot should match the corresponding cut-out on the module. 7. Carefully press the module into place until the retaining clips snap into position. Make sure that the clips are locked properly. DIMM Retaining clip Figure 17. DIMM retaining clips 8.
