System Power Specifications
The following tables provide information to help determine the amount of ac power needed for
your computer room.
Table 2-4 lists the ac power requirements for the server.

1 Maximum power is the sum of the worst case power consumption values of every subsystem in the HP 9000 rp4410
or rp4440 server. To calculate the worst case power consumption for your facility installation, use these values.
2 Typical power consumption values were measured while running power intensive applications. These values are
generally lower than maximum power numbers because all the subsystems in the server rarely draw maximum
power simultaneously and for long durations.
