System Specifications
System specifications for the HP 9000 rp8440 are described in the following sections.
System Power Specifications
Table 39and Table 40 (page 159) list the system power, the power dissipation and the cooling
requirements for the server.

See Note 158375720Maximum Theoretical Power
30A @ 180 VAC, See Note 25400– – –Marked Electrical Power
See Note 338663789User 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: (Input power at the ac input expressed in Watts and
Volt-Amps.)
The measured maximum worst case power consumption. This number represents the largest 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.
Typical Power Dissipation and Cooling
Table 40 provides calculations for the configurations as described in the table.
