Running the SSU is optional after you install or remove a PCI or ISA

Power Supplies
The system can be configured with two or three power supply modules. 
These configurations use a power share board that distributes the power 
supplied by two supply modules to various system components. Table 5 
shows the power distribution using the power share board. Configurations 
using three power supply modules use the same power share board as those 
using two supply modules. The third module acts as a hot spare and allows 
hot swapping of failed power supply modules.
