AC Power
Consumption The HP 9000 rp7420 Server power consumption will vary greatly depending on the hardware
configuration and the input line voltages supplied at customer sites. Because of the disparity of
line voltages throughout the world it's best to represent power consumption in VA (Volt*Amperes).
With power consumption being of high concern throughout the world, it's necessary to specify
consumption in a couple of different ways.
Maximum Theoretical Power: or "Maximum Configuration" (Input power at the ac input
expressed as 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.
Marked Electrical Power: (Input power at the ac input expressed as Volt-Amps.)
The server 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.
Typical Maximum Power: or User Expected Maximum Power, "Typical Configuration"
(Expressed as 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 load. This number can safely be used to compute thermal loads
and power consumption for the system under all conditions.
