Installing Memory
IMPORTANT: You must pull the AC power plugs on the server every time you modify the DIMMs.
If you do not pull the AC power plugs, the system does not display the correct DIMM information.
To install memory, follow these steps:
1. Unlatch the cover release lever on the top cover and remove the memory carrier assembly
cover. See “Removing the Memory Carrier Assembly Cover” (page 13).
NOTE: You do not need to fully remove the top cover to service this component; however,
the top cover release lever must be open.
2. Remove the memory carrier assembly. See “Removing the Memory Carrier Assembly”
(page 21).
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 24).
b. Use Figure 9: “8-DIMM Memory Carrier Board Slot IDs” (page 25), or Figure 10:
“24-DIMM Memory Carrier Board Slot IDs” (page 25), 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 26).
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.
5. Remove the memory carrier assembly side cover.
a. Press the release tabs (Figure 7 (page 22)) 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 8 (page 23)).
c. Lift the side cover off the assembly.
