User-Expected Maximum Power
Note 1: Maximum Theoretical Power: or “Maximum Configuration” (Input power at the ac input
expressed in Watts and Volt-Amps to take into account Power factor correction.)The calculated
sum of the maximum worst case power consumption for every subsystem in the server. This
number will never be exceeded by a functioning server for any combination of hardware and
software under any conditions.
Note 2: Marked Electrical Power: (Input power at the ac input expressed in Volt-Amps.)The
Marked Electrical Power is the rating given on the chassis label and represents the input power
required for facility ac power planning and wiring requirements. This number represents the
expected maximum power consumption for the server based on the power rating of the bulk
power supplies. This number can safely be used to size ac circuits and breakers for the system
under all conditions.
Note 3: User-Expected Maximum Power: or User Expected Maximum Power, (Input power at
the ac input expressed in Watts and Volt-Amps.)The measured maximum worst case power
consumption. This number represents the larges power consumption that HP engineers were
able to produce for the server with any combination of hardware under laboratory conditions
using aggressive software applications designed specifically to work the system at maximum
