Power Supplies
NOTE:
The following table lists the maximum supported configuration
where power supply redundancy is guaranteed.
NOTE:
Configurations higher than indicated in the table may change the
power supply mode to non-redundant. In non-redundant mode if the power
requirement exceeds the installed system power capacity, the BIOS will
throttle the CPUs. Also, if CPU Power Capping is enabled, then CPU
throttling occurs on configurations that exceed the cap value.
