Chapter 1 Introduction
The Eaton
®
Advanced Enclosure Power Distribution Unit (ePDU
®
) is an intelligent ePDU that is designed to
distribute power within a standard 19-inch rack. A wide range of models let you connect and manage C13
and C19 outlets from a single power connection.
This document describes troubleshooting problems you might encounter with ePDU hardware and firmware
set
up and operation. Information is provided to assist you in identifying problems, suggesting actions you might
take to resolve the problem, and clearing expired alarm notifications.
Identifying Problems
The system provides a rich troubleshooting toolset to help isolate and analyze problems that affect or prevent
proper ePDU operation. Some significant problem isolation tools for ePDU troubleshooting are:
l
Hardware power outlet LEDs on the ePDU that indicate current operating status
l
ePDU operation notifications through the ePDU LCD panel or the ePDU management software application
Web interface
l
E-mail notification of an event history log
Checking the Power Outlet LEDs on the ePDU
Power outlets are arranged in groups called factory groups and are color-coded on each ePDU model. LEDs for
each factory group are located on the top surface of the ePDU (see Figure 1).
The display mode of a status LED indicates the current ePDU operating status:
l
LED is illuminated (On) when an outlet is powered
l
LED is Off if an outlet is unpowered
l
LED flashes On and Off when an outlet or factory group alarm is triggered

Checking for Software Notification Alerts on the Interfaces
The ePDU is designed for durable, automatic operation. If a potential operating problem occurs, the ePDU
issues a software notification to alert you. Notifications are provided on the ePDU LCD panel interface and the
ePDU Network Management Card Web interface.
NOTE The ePDU serial interface is useful, but it does not provide software notification
alerts. The serial interface is primarily used for initial startup and configuration.
However, you can use this interface to retrieve and reset current meters,
measurements, or threshold values to correct problems caused by existing
configuration settings.
Introduction
Eaton Advanced ePDU Troubleshooting Guide P-164000140—Rev 1 www.eaton.com/ePDU 2
Alarm and event software notification alerts are provided in this document.
l
Alarm messages indicate a fault condition is active or imminent. Alarms display on both interfaces and are
recorded in the event log. Alarms require a response.
l
Event messages are conditions recorded in the event log as status information, such as Power On. Events
display on both interfaces and are recorded in the event log. Events do not require a response.
Alarms and events are recorded in the event log as records of w
hen alerts occurred and, if applicable, when
they were cleared.
NOTE Error messages are included in this document, but they are not software notification
alerts. They display due to incorrect entries or failed processes. The error message
prompts you to provide correct information or retry an operation.
LCD Panel
The ePDU has a three-button, graphical LCD panel. The LCD panel is located on the top surface of the ePDU
(see Figure 2). You can use this interface to retrieve current ePDU alarm data or to change ePDU operation
settings to resolve certain ePDU problems.
Alarms can also display automatically. For example, the dis
play can show active alarms as they occur, or
particular displays may update due to a change in operating state.
Figure 2. ePDU LCD Panel and Control Buttons
Web Interface
The ePDU Network Management Card Web interface allows you to remotely connect to ePDUs using a PC
with an Ethernet connection to an internet browser. If the ePDU is experiencing active system alarms, the Web
inter
face prominently displays alarm information (see Figure 3):
l
In the Menu Bar, the text for active alarms is red.
l
In the Refresh Bar at the bottom of the window, an alarm notification message displays.
l
Opening the Active Alarms page from the Menu Bar provides a list of the current active alarms.

- Use the Logs & Notifications menu selections to see
a list of the most recent events or clear the log.
l
Settings
- Use Settings menu selections to correct prob
lems arising from configuration settings.
Checking for E-mail Notifications with History Reports
Use the Web interface to set e-mail notifications (E-mail Notification page) and trap receivers (Trap Notification
page). E-mail notifications include comprehensive or filtered event history reports attached to daily e-mail
messages. The detailed data logs you receive can be useful for historical statistical analysis and diagnostics.
Introduction
Eaton Advanced ePDU Troubleshooting Guide P-164000140—Rev 1 www.eaton.com/ePDU 4
Resolving Problems
After the issue is identified and isolated, try to determine the root cause and then resolve the problem. For
example, the issue may be a physical or mechanical problem, a problem with connectivity, or a problem with
the existing settings for value ranges and thresholds.
First, check the troubleshooting reference
tables in the Troubleshooting chapter in this document. There are
eight tables associated with different categories of problems. Find the table that is associated with the type of
problem you are investigating, including the following:
l
Power Outlets
l
Chassis and Installation
l
Circuit Breakers
l
LCD Alarms
l
COM Ports
l
ePDU Web Interface Alarm and Events
l
Error Messages
l
Accessories
Each table has three columns defining problems or specifying interf
ace messages, providing possible root
causes, and suggesting actions that may help you solve problems.
If you cannot find a resolution to a problem in the tables, contact customer service or a local representative for
guidance or product part replacement.
Clearing Alarm Notifications
The are several ways to clear alarm notifications. For example, you can clear accumulated events from the Event
Log display on ePDU interfaces or suppress blinking alarm indicators on the ePDU.
Clear the Web Interface Event Log
To clear the Event Log, go to the ePDU Web interface menu bar and select “Logs” under “Logs &
Notifications.” The “Logs” page displays the current Event Log. Click Clear.
Clear the LCD Panel Event Log
To clear the Event Log, use the control buttons on the ePDU LCD panel to access the menu item, “CLEAR
EVENT LOG.” Select Yes.
Suppress ePDU Alarm Indicators
To suppress ePDU alarm indicators, such as blinking LEDs or blinking LCD alarm displays, touch any control
button on the panel.
NOTE Not all alarms or events need to be cleared. Some alarms automatically clear when
the condition resolves. For example, if a load over current alarm is generated, the
alarm is cleared when the current drops 0.25A below the level (alarm hysteresis).
