8.1 Memory Configuration
This section describes the configuration and location of memory.
A maximum of 32 memory modules can be implemented in one CPU memory unit.
One chassis can contain two CPU memory units; the CPU memory unit upper and
lower. Therefore, the maximum number of memory modules that can be implemented
in one chassis is 64.
Figure 8-1 shows the memory locations and the memory groups of the CPU memory
unit lower, while Figure 8-2 shows those of the CPU memory unit upper.
