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
Table 7-1 System Power Requirements for the HP Integrity rx7640 and HP 9000 rp7440 Servers
Power Required(50-60 Hz)
Maximum Theoretical Power
Marked Electrical Power
User-Expected Maximum Power
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.
