System Power Specifications
Table B-4 and Table B-5 list the AC power requirements for an hp rp7405/rp7410 server. These tables provide
information to help determine the amount of AC power needed for your computer room.
Future upgrades may increase the Maximum Theoretical System Power to 3400 VA.
Maximum power is the sum of the worst case power consumption of every subsystem in the box, and should
be used to size worst case power consumption for facility installation. Typical power consumption numbers
are what HP engineers have measured running power intensive applications. These are generally lower than
maximum power numbers due to the fact that getting all of the subsystems in the box to simultaneously draw
maximum power for long durations being uncommon.
