Overview
Important safety information
NOTE: The HP Intelligent Power Distribution Unit (iPDU) is intended for use only with
information technology equipment (ITE) loads in racks or similar computer room applications.
Extension Bars ship with some kits. These Extension Bars are designed for use with
Compaq/HP Power Distribution Core Units and HP Uninterruptible Power Systems (UPSs). The
Extension Bars can be used with other power sources, provided that the source includes
branch circuit overcurrent protection not exceeding 20 A.
WARNING: To reduce the risk of personal injury from electric shock, do not remove the
cover. There are no field-serviceable or user-serviceable components inside.
WARNING: A risk of personal injury from electric shock and hazardous energy levels exists.
The installation of options and routine maintenance and service of this product must be
performed by individuals who are knowledgeable about the procedures, precautions, and
hazards associated with AC power products.
Follow these safety precautions when connecting multiple hardware components to power sources.
WARNING: To reduce the risk of personal injury or damage to the equipment:
•Plug the input power cord into a grounded (earthed) electrical outlet that is located near
the equipment and is easily accessible.
•Be sure that the load products connected to the HP Intelligent Power Distribution Unit
(iPDU) are adjusted for, or otherwise capable of operation from the same line voltage
supplying the iPDU. Failure to verify the voltage can lead to severe equipment damage.
•Do not overload the iPDU. The total input current rating of all equipment connected to each
output cannot exceed the total output rating marked on the iPDU.
WARNING: To reduce the risk of personal injury from high-leakage current, verify earth
connection before connecting the power supply.
The summation of input power for multiple pieces of information technology equipment
through the use of power products can result in high-leakage currents.
If the total system leakage current for a system of components exceeds 3.5 mA:
•The use of a detachable input power cord is prohibited.
•The input power cord must be securely attached, and it should be connected to the AC
mains by hardwiring or through the use of a non-residential, industrial-style plug that
maintains positive earth connection.
•If the total system leakage current through the ground conductor exceeds 5% of the input
current per line under normal operating conditions, the system loads should be divided
among multiple power connections.

Overview 8
Introduction
The HP Intelligent Power Distribution Unit (iPDU) has an industry first feature of intelligent power discovery.
The iPDU automatically discovers HP ProLiant servers* powered by the iPDU, enabling data center
managers to know with certainty that installed equipment is powered as designed. Unexpected server
shutdowns can occur due to human error as routine maintenance tasks are performed, and are often the
first indication that a server is not powered as documented. The ability to automatically determine the
power topology increases reliability and allows data center managers to maximize the rack, power, and
thermal resources in the data center.
The iPDU intelligent power discovery also enables HP Thermal Logic solutions, such as Insight Control
Power Manager advanced group power capping for ProLiant DL/ML and Integrity servers with iLO 2
management processors and optional upgrade licenses, to reach their full potential by reducing human
error when assigning servers to a power capping group.
The iPDU enables you to monitor, manage, and control power environments. Multiple devices can monitor
the iPDU over the network connection.
The input voltage of a single phase iPDU is 200 to 240 VAC.
The input voltage of a three phase iPDU is 200 to 240 VAC or 380 to 415 VAC, depending on the
model.
For configuration and status monitoring, the iPDU includes:
•HP Intelligent PDU web interface (on page 34)—A graphical interface that is accessed with a web
browser
•HP Intelligent PDU Service Menu (on page 62)—A text-based menu that is accessed through telnet or
a terminal emulation session
To benefit from the latest product enhancements, update to the latest versions of firmware and software.
NOTE: To download the latest versions of firmware and software, see the HP website
(http://www.hp.com/go/rackandpower).
* Intelligent power discovery requires HP ProLiant servers with iLO 2 v2.0 or newer firmware or iLO 3
v1.05 or newer firmware, combined with the Intelligent Extension Bar, PLC power cables, and HP ProLiant
94% efficiency common slot power supplies.

Installing the HP Intelligent Power Distribution Unit 17
Installing the 1U brackets
The rack ears are reversible, so the iPDU can be installed with either the circuit breakers or the power
cords facing forward. Two iPDUs can be mounted in a 1U configuration by mounting one iPDU in the
front of the rack and the other iPDU in the rear of the rack.
Installing the Core Unit in the rack
The Core Unit can be mounted in the rack two different ways, depending on whether you install the 0U
brackets (A) or the 1U brackets (B) on the Core Unit.
Installing the 1U Core Unit in a square-hole rail
NOTE: Use the M6 screws and cage nuts that shipped with the rack when installing in a
square-holed rail.
