Maximum configuration
a
a. Maximum power is the sum of the worst case power consumption values of every subsystem in your
hp Integrity rx4640. These worst case values should be used to calculate the worst case power
consumption for your facility installation.
1368 1440 Maximum Theoretical
Typical configuration
b
b. 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
your HP Server rarely draw maximum power simultaneously and for long durations.
