Component Power Requirements
Table 1-4 and Table 1-5 list the AC power requirements for a rp8400 server. These tables provide information
to help determine the amount of AC power needed for your computer room. To determine the overall power
requirements of your specific system, see Table A-3 on page 47 and Table A-4 on page 47.
Use Appendix A to determine the actual values required for your system.
Future upgrades may increase the Maximum Theoretical System Power to 6000 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.
Power Cords
Table 1-6 lists the various power cables available for use with a rp8400 server. Each power cord is 15 feet (4.5
meters) in length with a IEC 60320-1 C19 female connector attached to one end.
Power Distribution Unit (PDU)
A 60-amp 3U high PDU may be used at customer sites to reduce the number of circuit breaker slots needed.
The North America E7683A PDU will have four 20A circuit breakers. The International E7684A PDU will
have four 16A circuit breakers. Two IEC 320-20 outlets are associated with each breaker providing a total of
eight IEC 320-20 outlets. The PDU will be 3U high and will be rack-mounted in the server cabinet
Documentation for installation will accompany the PDU. The documentation may also be found at the
external Rack Solutions Web site at http://www.hp.com/racksolutions. The internal Web site is
http://racksolutions.corp.hp.com. This PDU may be referred to as a Relocatable Power Tap outside HP.
