Introduction
Product Features
The Dell® Managed Rack Power Distribution Unit (PDU) is a stand-alone, networkmanageable power distribution device. The Rack PDU provides real-time remote
monitoring of connected loads. User-defined alarms warn of potential circuit overloads.
The Rack PDU provides full control over outlets through remote commands and user
interface settings.
You can manage a Rack PDU through its Web interface, its command line interface
(CLI), or Simple Network Management Protocol (SNMP):
• Access the Web interface using Hypertext Transfer Protocol or using secure HTTP
(HTTPS) with Secure Sockets Layer (SSL). See Logging On to the Web Interface.
• Access the command line interface through a serial connection, Telnet, or Secure
Shell (SSH). See About the Command Line Interface.
• Use an SNMP browser and the Dell Management Information Base (MIB) to manage
your Rack PDU.
Rack PDUs have these additional features:
• Peak load, and power and energy monitoring for all connected loads.
• Voltage, current, and power monitoring for phases.
• Power monitoring for each outlet.
• Configurable alarm thresholds that provide network and visual alarms to help avoid
overloaded circuits.
• Four levels of user access accounts: Administrator, Device User,
Read-Only User, and Outlet User.
USER’S GUIDE
Managed Rack PDU
• Independent outlet control.
• Configurable power delays.
1
• Up to twenty-four independent outlet user accounts.
• Event and data logging. The event log is accessible by Telnet, Secure CoPy (SCP),
File Transfer Protocol (FTP), serial connection, or Web browser (using HTTPS
access with SSL, or using HTTP access). The data log is accessible by Web
browser, SCP, or FTP.
• E-mail notifications for Rack PDU and system events.
• SNMP traps, Syslog messages, and e-mail notifications based on the severity level
or category of the Rack PDU and system events.
• Security protocols for authentication and encryption.
The Rack PDU does not provide power surge protection. To ensure
that the device is protected from power failure or power surges,
connect the Rack PDU to an uninterruptible power supply (UPS).
Access priorities for logging on
Only one user at a time can log on to the Rack PDU. The priority for access, beginning
with the highest priority, is as follows:
• Local access to the command line interface from a computer with a direct serial
connection to the Rack PDU
• Telnet or Secure Shell (SSH) access to the command line interface from a remote
computer
• Web access
See SNMP for information about how SNMP access to the Rack PDU is
controlled.
USER’S GUIDE
Managed Rack PDU

Types of user accounts
The Rack PDU has four levels of access (Administrator, Device User, Read-Only User,
and Outlet User), which are protected by user name and password requirements.
• An Administrator can use all of the menus in the Web interface and all of the
commands in the command line interface. The default user name and password are
both admin.
• A Device User can access only the following:
– In the Web interface, the menus on the Device Manager tab, the Environment
tab, and the event and data logs, accessible under the Events and Data headings
on the left navigation menu of the Logs tab. The event and data logs display no
button to clear the log.
– In the command line interface, the equivalent features and options.
The default user name and password are both device.
• A Read-Only User has the following restricted access:
– Access through the Web interface only.
– Access to the same tabs and menus as a Device User, but without the capability to
change configurations, control devices, delete data, or use file transfer options.
Links to configuration options are visible but disabled. The event and data logs
display no button to clear the log.
The default user name and password are both readonly.
To set User Name and Password values for the three account types above,
see Setting user access.
USER’S GUIDE

• An Outlet User has the following restricted access:
– Access through the Web interface and command line interface.
– Access to the same menus as a Device User, but with limited capability to change
configurations, control devices, delete data, or use file transfer options. Links to
configuration options are visible but are disabled. The Outlet User has access to
the Outlet Control menu option that allows the user to control the outlets assigned
by the Administrator. Outlet Users cannot clear the event or data logs.
The user name and password are defined by the Administrator during the process of
adding a new Outlet User.
Getting Started
To start using the Rack PDU:
1. Install the Rack PDU using the Rack Power Distribution Unit Installation
Instructions that were shipped with your Rack PDU.
2. Apply power and connect to your network. Follow the directions in the Rack
Power Distribution Unit Installation Instructions.
3. Establish network settings. (See Establishing Network Settings.)
4. Begin using the Rack PDU by way of one of the following:
• Web Interface
• Command Line Interface
• Rack PDU Front Panel
USER’S GUIDE
Managed Rack PDU

Establishing Network Settings
You must configure the following TCP/IP settings before the Rack PDU can operate on
a network:
• IP address of the Rack PDU
• Subnet mask
• Default gateway
If a default gateway is unavailable, use the IP address of a computer
that is located on the same subnet as the Rack PDU and that is
usually running. The Rack PDU uses the default gateway to test the
network when traffic is very light.
Do not use the loopback address (127.0.0.1) as the default gateway
address for the Rack PDU. It disables the card and requires you to
reset TCP/IP settings to their defaults using a local serial login.
TCP/IP configuration methods
Use one of the following methods to define the TCP/IP settings needed by the Rack
PDU:
• BOOTP and DHCP configuration
• Command Line Interface
USER’S GUIDE
Managed Rack PDU
5
BOOTP and DHCP configuration
The default TCP/IP configuration setting, DHCP, assumes that a properly configured
DHCP server is available to provide TCP/IP settings to Rack PDUs. You can also
configure the setting for BOOTP.
A user configuration (INI) file can function as a BOOTP or DHCP boot file. For more
information, see Use an .ini File.
BOOTP. For the Rack PDU to use a BOOTP server to configure its TCP/IP settings, it
must find a properly configured RFC951-compliant BOOTP server.
In the BOOTPTAB file of the BOOTP server, enter the Rack PDU’s MAC address, IP
address, subnet mask, and default gateway, and, optionally, a bootup file name. Look
for the MAC address on the bottom of the Rack PDU or on the Quality Assurance slip
included in the package.
When the Rack PDU reboots, the BOOTP server provides it with the TCP/IP settings.
• If you specified a bootup file name, the Rack PDU attempts to transfer that file from
the BOOTP server using TFTP or FTP. The Rack PDU assumes all settings specified
in the bootup file.
• If you did not specify a bootup file name, you can configure the other settings of the
Rack PDU remotely through its Web Interface or Command Line Interface.
To create a bootup file, see your BOOTP server documentation.
USER’S GUIDE
Managed Rack PDU

DHCP. You can use an RFC2131/RFC2132-compliant DHCP server to configure the
TCP/IP settings for the Rack PDU.
This section summarizes the Rack PDU’s communication with a
DHCP server. For more detail about how a DHCP server can configure
the network settings for a Rack PDU, see DHCP response options.
1. The Rack PDU sends out a DHCP request that uses the following to identify
itself:
• A Vendor Class Identifier
• A Client Identifier (by default, the MAC address of the Rack PDU)
• A User Class Identifier (by default, the identification of the application firmware
installed on the Rack PDU)
2. A properly configured DHCP server responds with a DHCP offer that includes
all the settings that the Rack PDU needs for network communication. The
DHCP offer also includes the Vendor Specific Information option (DHCP option
43). The Rack PDU can be configured to ignore DHCP offers that do not
encapsulate the vendor cookie in DHCP option 43 using the following
hexadecimal format. (The Rack PDU does not require this cookie by default.)
Option 43 = 01 04 31 41 50 43
Where:
• The first byte (01) is the code.
• The second byte (04) is the length.
• The remaining bytes (31 41 50 43) are the vendor cookie.
See your DHCP server documentation to add code to the Vendor
Specific Information option.
USER’S GUIDE
Managed Rack PDU
7
Note: By selecting the Require vendor specific cookie to accept
DHCP Address check box in the Web interface, you can require the
DHCP server to provide a vendor cookie, which supplies information
to the Rack PDU Administration > Network>TCP/IP>ipv4 settings.
Command Line Interface
1. Log on to the command line interface. See Logging on to the Command Line
Interface.
2. Contact your network administrator to obtain the IP address, subnet mask, and
default gateway for the Rack PDU.
3. Use these three commands to configure network settings. (Text in italics
indicates a variable.)
a. tcpip -i yourIPaddress
b. tcpip -s yourSubnetMask
c. tcpip -g yourDefaultGateway
For each variable, type a numeric value that has the format xxx.xxx.xxx.xxx.
For example, to set a system IP address of 156.205.14.141, type the following
command and press E
tcpip -i 156.205.14.141
4. Type exit. The Rack PDU restarts to apply the changes.

Command Line Interface
About the Command Line Interface
You can use the command line interface to view the status of and manage the Rack
PDU. In addition, the command line interface enables you to create scripts for
automated operation. An Administrator has full access to the command line interface, a
Device user and Outlet user have limited access, and a Read-Only user is completely
restricted. (For additional details, see Types of user accounts.)
You can configure all parameters of a Rack PDU (including those for which there are
not specific CLI commands) by using the CLI to transfer an INI file to the Rack PDU.
The CLI uses XMODEM to perform the transfer. However, you cannot read the current
INI file through XMODEM.
Logging on to the Command Line Interface
To access the command line interface, you can use either a local (serial) connection or
a remote (Telnet or SSH) connection with a computer on the same network as the Rack
PDU.
Remote access to the command line interface
You can access the command line interface through Telnet or SSH. Telnet is enabled
by default. Enabling SSH disables Telnet.
To enable or disable these access methods, use the Web interface. On the
Administration tab, select Network on the top menu bar, and then the access option
under Console on the left navigation menu.

Telnet for basic access. Telnet provides the basic security of authentication by user
name and password, but not the high-security benefits of encryption.
To use Telnet to access the command line interface:
1. From a computer on the same network as the Rack PDU, at a command prompt,
type telnet and the IP address for the Rack PDU (for example, telnet
139.225.6.133, when the Rack PDU uses the default Telnet port of 23), and
press
If the Rack PDU uses a non-default port number (from 5000 to 32768), you must
include a colon or a space, depending on your Telnet client, between the IP address
(or DNS name) and the port number. (These are commands for general usage:
some clients do not allow you to specify the port as an arguement and some may
require extra commands.)
2. Enter the user name and password (by default, admin and admin for an
Administrator, or device and device for a Device User).
SSH for high-security access. If you use the high security of SSL for the Web
interface, use SSH for access to the command line interface. SSH encrypts user
names, passwords, and transmitted data. The interface, user accounts, and user
access rights are the same whether you access the command line interface through
SSH or Telnet, but to use SSH, you must first configure SSH and have an SSH client
program installed on your computer.

Command Syntax
Item Description
- Options are preceded by a hyphen.
< > Definitions of options are enclosed in angle brackets. For
example:
-dp <device password>
[ ] If a command accepts multiple options or an option accepts
mutually exclusive arguments, the values may be enclosed in
brackets.
| A vertical line between items enclosed in brackets or angle
brackets indicates that the items are mutually exclusive. You must
use one of the items.
Example of a command that supports multiple options:
user [-an <admin name>] [-ap <admin password>]
In this example, the user command accepts the option -an, which defines the
Administrator user name, and the option -ap, which defines the Administrator
password. To change the Administrator user name and password to XYZ:
1. Type the user command, one option, and the argument XYZ:
user -ap XYZ
2. After the first command succeeds, type the user command, the second option, and
the argument XYZ:
user -an XYZ

Example of a command that accepts mutually exclusive arguments for an
option:
alarmcount -p [all | warning | critical]
In this example, the option -p accepts only three arguments: all, warning, or critical. For
example, to view the number of active critical alarms, type:
alarmcount -p critical
The command will fail if you type an argument that is not specified.
Command Response Codes
The command response codes enable scripted operations to detect error conditions
reliably without having to match error message text:
The CLI reports all command operations with the following format:
E [0-9] [0-9] [0-9] : Error Message
Code Message Code Message
E000 Success E105 Command Prefill
