1. Unlatch the cover release lever on the top cover and remove the memory carrier assembly
cover. See
“Removing and Replacing the Memory Carrier Assembly Cover” (page 47) .
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 and Replacing the Memory Carrier
Assembly” (page 55) .
NOTE: To avoid damage to the handles, Hewlett Packard Enterprise 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 for the 48-DIMM memory carrier. For more information,
see
“Memory Load Order” (page 60) .
b. Use Figure 27 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 61) .
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 25 ).
5. Remove the memory carrier assembly side cover.
a.
Press the release tabs ( Figure 25 ) on both sides of the extraction handle release button
until the side cover releases from the top center of the assembly.
