NOTE Electrical practices and suggestions in this guide are based on North American practices. For

countries outside North America, local electrical codes will take precedence over North
American electrical codes.

An example would be the recommendation that the PE (protective earthing) conductor be green
with yellow stripes. This requirement is a North American directive and does not override the
local code requirements for a country outside North America.

Local authority has jurisdiction [LAHJ] and should make the final decision regarding
adherence to country-specific electrical codes and guidelines.

Throughout this manual, the [LAHJ] acronym will be used to indicate Local Authority Has Jurisdiction.

Electrical Specifications

This section provides electrical specifications for rp8400 servers.

Grounding

The site building shall provide a safety ground/protective earth for each AC service entrance to all rp8400
cabinets.

Install a PE (protective earthing) conductor that is identical in size, insulation material, and thickness to the
branch-circuit supply conductors. The PE conductor must be green with yellow stripes. The earthing
conductor described is to be connected from the unit to the building installation earth or, if supplied by a
separately derived system, at the supply transformer or motor-generator set grounding point.

Circuit Breaker

The Marked Electrical for the rp8400 server is 15 amps. The recommended circuit breaker size is 20 amps for
North America. For countries outside North America, consult your local electrical authority having
jurisdiction for the recommended circuit breaker size.

The rp8400 contains four C20 power receptacles located at the bottom rear bulkhead. A minimum of two
power cords must be used to maintain normal operation of the rp8400. A second set of two cords can be added
to improve system availability by protecting, for example, against power source failures or accidentally
tripped circuit breakers. The rp8400 is capable of receiving AC input from two different AC power sources.

System Power Requirements

Table 1-4 and Table 1-5 on page 8 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.

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.
