NOTE: To avoid damage to the handles, HP recommends rotating the handles inward and snapping them into place when servicing the system DIMMs or any time the carrier is out of the chassis. Before replacing the memory carrier, press the button to release the extraction handles. Use the handles to replace the memory carrier into the chassis.

3.Complete the following memory installation prerequisite tasks before installing the memory:

a.Determine the DIMM load order as appropriate for the 8-DIMM or 24-DIMM memory carrier. For more information, see “Memory Load Order” (page 68).

b.Use Figure 3-9:“8-DIMM Memory Carrier Board Slot IDs” (page 69), or Figure 3-10:“24-DIMM Memory Carrier Board Slot IDs” (page 70), to determine the DIMM slots to populate.

c.Read, understand, and follow the general guidelines to install memory in the server. See “Memory Loading Rules and Guidelines” (page 70).

4.Lay the memory carrier assembly on side 0 or side 1 so that the memory carrier side that contains the DIMM slots that you will install DIMMs into faces upward (Figure 3-8 (page 67)).

5.Remove the memory carrier assembly side cover.

a.Press the release tabs (Figure 3-8 (page 67)) on both sides of the extraction handle release button until the side cover releases from the top center of the assembly.

b.Rotate the side cover slightly to free the tabs from the retaining slots at the base of the assembly (Figure 3-8 (page 67)).

c.Lift the side cover off the assembly.

6.Install the DIMMs (Figure 3-11).

a.Align the DIMM with the slot located on the memory board, and align the key in the connector with the notch in the DIMM.

b.Push on each end of the DIMM firmly and evenly until it seats into the slot.

c.Ensure that the extraction levers are in the fully closed position.
