Power Allocated Components	Oracle ILOM Power Allocation Behavior
Oracle Rackmounted Servers	Power allocated to an Oracle rackmounted server is the maximum power the rackmount chassis components are capable of consuming. This value represents the maximum power wattage consumed by the processors, memory, I/O, fans, as well as the power loss across the power supplies. If the rackmount chassis contains slots for hot-pluggable components, the Power Allocated property value shown represents the maximum power wattage required for the most power-consuming component that can be installed in the hot-pluggable slot.
Hot-Pluggable Chassis Components	Oracle ILOM automatically displays a pre-allocated maximum power value for any known hot-pluggable component that is installed in a hot-plug designated chassis slot location. For example: For rackmount hot-pluggable slots, Oracle ILOM displays the known maximum power wattage value required for a hot-pluggable component. To determine which components or slots in a rackmounted chassis are hot-pluggable, refer to the Oracle server documentation.
Chassis Component Categories	For chassis component categories that include multiple instances of the same component, Oracle ILOM presents the total sum of power allocated for a component category (fans), as well as the total sum of power allocated to an individual component (fan0).
Power Supply Unit (PSU)	Oracle ILOM automatically allocates power to the power supply to account for power losses between the wall outlet and the managed device.
