1Easy PDU User Guide for 3-Phase Switched Rack PDU
Introduction
Product Features
This APC by Schneider Electric Rack Power Distribution Unit, the Switched Easy PDU, may be used as a
stand-alone, network-manageable power distribution device. The Switched Easy PDU provides real-time
remote monitoring of connected loads. User-defined alarms warn of potential circuit overloads. You can
manage an Easy PDU through its Web User Interface (Web UI), or Simple Network Management Protocol
(SNMP).
Switched Easy PDUs have these additional features:
• Monitor device power, apparent power, power factor and energy
• Monitor phase voltage, current
• Configurable alarm thresholds with network access to help avoid overloaded circuits
• Various levels of access: Super User and General User. (Only one user at a time may log in at each
access level)
• Individual outlet control
• Configurable power (On/Off delays)
• RS485 cascade connection: Up to 4 Easy PDUs can be connected using an RS485 serial interface so
that only one network connection is necessary
• Event logging
• Modbus-TCP (Disabled as default configuration)
• SNMP traps (V1, V2c, and V3)
• Security protocols for authentication and encryption.
• Log file and firmware can be upgraded by inserting a USB Flash drive into the USB port on the Display
Interface of the Easy PDU
• Synchronize the time with the SNTP Server.
NOTE: There is no Real Time Clock (RTC) battery on this device. You will need to set a SNTP server
the first time you log in.
Getting Started
To start using the Easy PDU:
1. Install the Easy PDU using the Installation Instructions that were shipped with your device.
2. Apply power and connect to your network. Follow the directions in the Installation Instructions.
3. Establish network settings (See “Establish Network Settings” on page 3.)
4. Begin using the Easy PDU by way of one of the following:
– Web User Interface (See “Web User Interface” on page 6.)
– Easy PDU Front Panel (See “Display Interface Overview” on page 4.)
– SNMP protocol (See “SNMP Settings” on page 13.)

Establish Network Settings
DHCP Configuration
The default TCP/IP configuration setting, DHCP, assumes that a properly configured DHCP server is available
to provide TCP/IP settings to the Easy PDU.
Static IP Configuration
You must define three TCP/IP settings for the Easy PDU before it can operate on the network:
• The IP address of the Easy PDU
• The subnet mask of the Easy PDU
• The IP address of the default gateway (only needed if you are going off segment)
For detailed information on how to configure the TCP/IP settings in a Easy PDU, see “Establish Network
Settings” on page 3.
Reset to Default
In some situations, users want to reset the settings to default. Press the Reset button for at least 10 seconds
and release. The Display Module will automatically reboot. The settings below will be reset to default:
• Alarm Threshold
• Network Settings
• SNMP Settings
• Users Settings (including usernames and passwords)
• SNTP configurations in Time Settings
The settings below will NOT be changed:
• Date and Time
• Electric Energy of each phase
• Event Log

Web User Interface
Supported Web Browsers
You can use Microsoft® Internet Explorer® (IE) 11 or Google® Chrome® or Mozilla® Firefox® to access the
Easy PDU through its Web interface. Other commonly available browsers may work but have not been fully
tested by APC by Schneider Electric.
Log On to the Web User Interface
You can use the System IP address of the Easy PDU for the URL address of the Web interface. Use your
case-sensitive username and password to log on.
The default username and password for the Super User are both “apc”. The Super User must define a
username and password for the General User.
The DHCP is enabled by default. You must connect the Easy PDU to a network with a DHCP server before
you assign a static IP address to the Easy PDU. (See “Establish Network Settings” on page 3 for more
information.) The auto-assigned IP address can be requested from the network status page in the LCD display
of the Display Module. On your computer, type the IP address of the Easy PDU in your Web browser’s URL
address field (e.g., 192.168.0.162 or http://192.168.0.162) and press ENTER.
Status
Select the Status tab to view:
• System information
• Electrical use status

Time Settings
The time settings page allows users to configure the system time of the Easy PDU. You can set the time
manually or synchronize the time through a Simple Network Time Protocol (SNTP) server.
NOTICE
It is recommended that you configure SNTP when you use the Easy PDU the first time or you will need to
set the system time manually with the Easy PDU is powered off. The time record in the Log may be
incorrect If this is not done.
Selecting the SNTP Switch enables the Easy PDU to synchronize the time from the SNTP server
automatically. If SNTP is enabled, inputs in the Date and Time boxes will NOT be effective.
• Input the IP address of the time server that supports SNTP in the box of SNTP Server IP.
• Input your time zone offset value to the SNTP Time Zone box.
• Change the SNTP Update Interval if needed.
Deselect the SNTP Switch to disable automatic time synchronization. Click the “Get Local PC Time” button to
get the current time from the PC that has the Web page loaded and fill the boxes of Date and Time. You can
also input the date and time manually to the boxes.
Click the “Apply” button to apply your changes.

Troubleshooting
For problems that persist or are not described here, contact APC by Schneider Electric Customer
Care at www.apc.com.
Easy PDU Access Issues
ProblemSolution
If the Network Status LED of the Easy PDU is green, try to
ping another node on the same network segment as the
Easy PDU. If that fails, it is not a problem with the Easy PDU.
Unable to ping the Easy PDU
Cannot access the Web User Interface
If the Network Status LED is not green, or if the ping test
succeeds, perform the following checks:
• Verify all network connections.
• Verify the Network Settings of the Easy PDU
• Verify that HTTP or HTTPS access is enabled.
• Make sure you are specifying the correct URL — one
that is consistent with the security system used by the
Easy PDU. SSL requires HTTPS, not HTTP, at the
beginning of the URL.
• Verify that you can ping the Easy PDU.
• Verify that you are using a Web browser supported for
the Easy PDU. See “Supported Web Browsers” on
page 6.
• If the Easy PDU has just restarted and SSL security is
being set up, the Easy PDU may be generating a
server certificate. The Easy PDU can take up to
several minutes to create this certificate, and the SSL
server is not available during that time
21Easy PDU User Guide for 3-Phase Switched Rack PDU
SNMP Issues
ProblemSolution
Unable to perform a GET or SET
Unable to receive traps at the NMS
• Verify the community name (SNMPv1 or SNMPv2c) or
the Authentication configuration (SNMPv3). See
“SNMP Settings”.
• Verify the UDP port 161 of NMS is correctly opened.
• Verify the Trap Proxy Server IP address configuration
is correct.
• Verify the UDP port 162 of NMS is correctly opened
Traps received at an NMS are not
identified
See your NMS documentation to verify that the traps are
properly integrated in the alarm/trap database.
