Electrical and Cooling Specifications
This section describes the electrical and power dissipation specifications for the HP Integrity rx7640
and HP 9000 rp7440 Servers.
Tables 7-1 and 7-2 list the system power, power dissipation, and cooling requirements for the
server. For more information on system power specifications, see Chapter 2.

1. “Maximum theoretical power” is used to describe input power at the AC input. It is expressed
in Watts and Volt-Amps to take into account power factor correction. The calculated sum is
the maximum worst-case power consumption for every subsystem in the server. This number
will not be exceeded by a properly functioning server for any combination of hardware and
software.
2. “Marked electrical power” is the input power measured 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.
3. “User-Expected Maximum Power” is the input power measured at the AC input expressed in
Watts and Volt-Amps, and the measured worst-case power consumption. This number represents
the largest power consumption for the server under laboratory conditions, using aggressive
software applications designed specifically to work the system at maximum loads and power
consumption.
Table 7-2 provides calculations for the configurations shown in the table.
