Overview

This document provides installation and configuration instructions for installing a Hewlett Packard Enterprise
G2 Series Metered, Switched, and Metered & Switched Power Distribution Units into a data center rack. Read
all instructions before operating the equipment and save this document for future reference.

Important safety information

See the complete regulatory compliance notices in Safety and Compliance Information for Server, Storage,
Power, Networking, and Rack Products on the

precautions specific to this device.

This PDU is intended only for Information Technology Equipment loads with linear/Power Factor Corrected
input current. If nonlinear loads are connected, the nameplate current rating of the PDU must be reduced by a
factor of 0.8.

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.

SAVE THESE IMPORTANT SAFETY PRECAUTIONS

Hewlett Packard Enterprise website. Follow the safety

Follow these safety precautions when connecting multiple hardware components to power sources.

Before you begin 7

WARNING: To reduce the risk of fire, electric shock, and damage to the equipment:

• HIGH LEAKAGE CURRENT. To reduce the risk of electric shock due to high leakage currents, make
sure that there is a reliable grounded (earthed) connection before connecting power distribution
products to AC power. If many products will be connected to a single PDU, it might be necessary to
conduct an evaluation of the installation to verify the total amount of leakage current. The total
combined leakage current must not exceed 5% of the input current for the PDU and associated load.

• Connect only to a circuit that provides circuit overcurrent protection of the appropriate current rating.

• Connect the input power cord to a grounded (earthed) electrical outlet that is located near the
equipment and is easily accessible.

• Make sure that all circuit breakers are in the off position before connecting input power.

• Make sure that the devices connected to the PDU are adjusted for, or otherwise capable of,
operation from the same line voltage supplying the PDU. Failure to verify the voltage can lead to
severe equipment damage.

• Do not overload the PDU. The total input current rating of all equipment connected to each output
cannot exceed the total output rating marked on the PDU.

• Use only the hardware provided to install the PDU.

• To reduce the risk of fire or electric shock, install this PDU in a temperature and humidity-controlled,
indoor environment, free of conductive contaminants. Do not operate near water or excessive
humidity (90% maximum noncondensing).

• Ambient temperature must not exceed 0°C to 60°C (32°F to 140°F).

• The internal components can become hot during operation. Allow sufficient time for the PDU to cool
before handling.

• Do not use a two-wire power cord in any product configuration.

• To isolate this equipment, disconnect the power cord.

DANGER: This PDU contains LETHAL VOLTAGES. NO repairs should be performed on this PDU,
except for the replacement of the management card as explained in Appendix C and Appendix D.
There are NO USER-SERVICEABLE PARTS inside the PDU. The installation of options, routine
maintenance, and service of this PDU must be performed by individuals who are knowledgeable about
the procedures, precautions, and hazards associated with AC power products.

THIS EQUIPMENT MUST BE CONNECTED TO AN ELECTRICAL SUPPLY.

Introduction

Classification overview

The Hewlett Packard Enterprise G2 Series Metered, Switched, and Metered & Switched Power Distribution
Units are intelligent PDUs designed to distribute power to IT equipment installed in a rack. These PDUs are
either single-phase (1Ph) or three-phase (3Ph) models with electrical metering and switching capabilities.
Each PDU provides power distribution to IT loads through C13, C19, or NEMA 5-20R outlets. The quantity
and location of outlets vary by model. The PDUs allow you to connect and manage these outlets from a single
power connection. The PDUs are managed from a web interface or a Command Line Interface (CLI) and are
viewed from a local display.

HPE PDUs are designed for use with HPE Standard, Advanced, and Enterprise racks, but are compatible
with most third-party data center racks. The PDU models vary in form factor, with several mounting
configurations available, including the following:

• HPE Metered PDU— Provides real-time local and remote power monitoring at each load segment,
enabling users to obtain information about power usage and available circuit capacity.

• HPE Switched PDU—Offers the same features as Metered PDUs and also provides controlled on/off
switching of individual outlets and groups of outlets, power sequencing delays to minimize inrush currents,
and support for unauthorized equipment provisioning.

• HPE Metered & Switched PDU—Offers the same features as Switched PDUs and also provides individual
outlet metering instead of load segment metering.

Features

The Hewlett Packard Enterprise G2 Series Metered, Switched, and Metered & Switched Power Distribution
Units have the following features:

• Lower profile on Vertical PDUs—Increases the serviceability area in the back of the rack.

• Multiple mounting option on Vertical PDUs—Can be mounted with outlets facing toward center, front or
back of the rack.

• Higher operating temperature—All G2 Series PDUs are rated for 60˚C (140˚F) operating temperature.

• Colored receptacles—Help to easily differentiate load segments and phases.

• Integrated cord retention on all C13 and C19 receptacles—Eliminates the need for cord retention brackets.

• Optional locking cords on all C13 and C19 receptacles—Eliminates the need for tie wraps on both ends of
the power cord connection.

• 1U PDUs with multiple mounting options—Can be mounted horizontally in a U space or in the true 0U
space between the RETMA rails.

• Hot Swappable Network Management Module—Allows power distribution during module replacement,
eliminating downtime.

• 1 Gb Ethernet—Eliminates the need for older network switches.

• Daisy-chain configuration—Enables networking of up to four of the same PDUs on one IP address.

• Enhanced sensor support—Supports up to six physical sensors (with optional hub) and eight
measurements per PDU, with a total of 32 measurements in a maximum daisy-chain configuration.

Introduction 9

• Dual-color OLED display—Provides local access to view configuration settings and automatically enters
sleep mode to conserve energy.

• Dual network access—Using a redundant power delivery configuration and separate network connections,
provides facilities management and IT (or Tenant) power consumption information.

• High-density models—Provides 24 outlets in a half-height or 48 outlets in a full-height PDU, keeping out of
the back of rack serviceability area.

• Security—Firmware has self-signed images and verified boot.

Form factors

Configuring local access

Connecting through a serial connection

You can access the following PDU information through a serial connection by running CLI commands.

• System configuration

• Network Configuration

• User Operation

• Device Settings

• Power Measurements

• Switch Outlets On/Off.

A serial connection also requires a terminal emulation program, such as HyperTerminal, or the use of an SSH
client, such as PuTTY.

Communicating through the serial port requires a specialized optional RJ45-DB9 cable, or you can create
your own cable. For more information on making your own cable, see

own cable.

Connecting the PDU to a computer

Serial cable pinout to create your

Procedure

1. Using the optional RJ45-DB9 cable, connect the RJ45 end to the port labeled Serial+RS485-1 on the front

panel of the PDU.

2. Connect the DB9 end of the cable to the serial connector on the computer.

Supported commands

The PDU CLI command set for managing and monitoring the PDU includes the following commands:

?

PDU help query

sys

PDU system configure and setting

net

PDU net application configure and setting

OLED display

The OLED display provides information about the PDU and connected devices. The OLED window flashes
red when a critical alarm is active. Information about the basic configuration of some settings is available
through the OLED. Information about the full configuration of all settings is available through the remote
interfaces. The OLED display orientation can be changed using an OLED setting. The display can be rotated
0° and 180°.

The PDU has a three-button, graphical OLED interface panel. Use the buttons to change the screen display,
retrieve specific performance data, or change configuration values. The display view can also change
automatically. For example, the display changes to show active alarms as they occur, or particular displays
update due to a change in operating state.

The OLED display has two modes.

• Screensaver mode—Cycles through a set sequence of screens that display current PDU values. Current
values are refreshed every 10 seconds. The user cannot select a custom sequence of screens. The
screensaver displays automatically after 30 seconds of inactivity from the start-up screen, a menu, or a
submenu. Values are refreshed every five seconds.

• Menu mode (OLED main menu)—The settings that display under each high-level (main) menu depend
on your PDU model.
