2.8 Installing Optional CPU Modules

The ES40CSLP rackmount system can contain up to four CPU modules. Figure 2-9 shows the
CPU slot locations on the system motherboard. The following configuration rules apply to the
CPU modules:
•
The first CPU module must be in CPU slot 0. CPU slot 0 is designated as the primary
CPU.
•
Additional CPU modules should be installed in ascending order by slot number.
•
All CPU modules must have the same clock frequency.
