Prepare the system for operation. For instructions, see "Preparing the 8001-12C or 8005-12N system for
operation after you remove and replace internal parts" on page 87.

Installing memory in the 8001-12C system

Learn how to install memory in the IBM Power System S821LC (8001-12C) system.

Placement rules for memory in the 8001-12C or 8001-22C system

Learn about the configurations and rules that apply to adding memory to the IBM Power System S821LC
(8001-12C) or the IBM Power System S822LC for Big Data (8001-22C) system.
Table 2 lists the supported memory DIMM feature codes and Table 3 shows the allowable memory
capacity points for the 8001-12C or 8001-22C system.
v Mixing of memory feature codes is not allowed.
v Mixing of memory from different manufacturers is not allowed.
v You must add four memory DIMMs at a time.
v The memory DIMMs need to be added in a sequence. Use Table 4 and Figure 17 on page 20 to
determine the memory placement.

Table 3. Memory configuration as a function of the number of DIMMs. You read this table by selecting the individual
DIMM size row in the leftmost column, then move to the right and select the columns for the memory capacity. The
value that is listed is the quantity of the memory feature code that can be ordered, which corresponds to the DIMM
size in the leftmost column.
