defects, or other reproductive harm.
Safety Guidelines

1. Installation of this product should only be performed by a person who has knowledge and
experience with electric power.
2. Make sure the line cord is disconnected from power before physically mounting or moving the
location of this product.
3. This product is designed to be used within an electronic equipment rack. The metal case of this
product is electrically bonded to the line cord ground wire. A threaded grounding point on the
case may be used as an additional means of protectively grounding this product and the rack.
4. Examine the branch circuit receptacle that will supply electric power to this product. Make sure
the receptacle’s power lines, neutral and protective earth ground pins are wired correctly and
are the correct voltage and phase. Make sure the branch circuit receptacle is protected by a
suitably rated fuse or circuit breaker.
5. If the product is a model that contains receptacles that can be switched on/off, electric power
may still be present at a receptacle even when it is switched off.
Tip 1: The outlet (socket) shall be installed near the equipment and shall be easily accessible.
Tip 2: For detailed information on any Raritan PDU's overcurrent protectors' design, refer to that
model's product specification on Raritan website's PDU Product Selector page
https://www.raritan.com/product-selector .

Raritan PXE is an intelligent power distribution unit (PDU) that allows
you to remotely monitor power consumed by IT equipment in the server
room or data center.
The intended use of the PXE is distribution of power to information
technology equipment such as computers and communication
equipment where such equipment is typically mounted in an equipment
rack located in an information technology equipment room.

Chapter 1: Introduction

APIPA and Link-Local Addressing
The PXE supports Automatic Private Internet Protocol Addressing
(APIPA).
With APIPA, your PXE automatically configures a link-local IP address
and a link-local host name when it cannot obtain a valid IP address from
any DHCP server in the TCP/IP network.
Only IT devices connected to
the same subnet can access the PXE using
the link-local address/host name. Those in a different subnet cannot
access it.
Once the PXE can get a DHCP-assigned IP address, it stops using APIPA
and the link-local address is replaced by the DHCP-assigned address.
Scenarios where APIPA applies:
DHCP is enabled on the PXE, but no IP address is assigned to the
PXE.
This may be caused by the absence or malfunction of DHCP servers
in the network.
Note: Configuration by connecting the PXE to a computer using a
network cable is an application of this scenario. See Connecting the
PXE to a Computer
(on page 14).
The PXE previously obtained an IP address from the DHCP server,
but the lease of this IP address has expired, and the lease cannot be
renewed, or no new IP address is available.
Link-local addressing:
IPv4 address:
Factory default is to enable IPv4 only. The link-local IPv4 address is
169.254.x.x/16 , which ranges between 169.254.1.0 and
169.254.254.255.
IPv6 address:
A link-local IPv6 address is available only after IPv6 is enabled on the
PXE. See
Configuring Network Settings (on page 111).
Host name - pdu.local:
You can type
https://pdu.local to access the PXE instead of typing the
link-local IP address.
Retrieval of the link-local address:
Perform the first three steps in the
Initial Network Configuration
via CLI
(on page 15).

Before You Begin
Before beginning the installation, perform the following activities:
Unpack the product and components
Prepare the installation site
Check the branch circuit rating
Fill out the equipment setup worksheet
Unpacking the Product and Components
1. Remove the PXE device and other equipment from the box in which
they were shipped. See
Package Contents (on page 1) for a
complete list of the contents of the box.
2. Compare the serial number of the equipment with the number on the
packing slip located on the outside of the box and make sure they
match.
3. Inspect the equipment carefully. If any of the equipment is damaged
or missing, contact Raritan's Technical Support Department for
assistance.
4. Verify that all circuit breakers on the PXE device are set to ON. If not,
turn them ON.
Or make sure that all fuses are inserted and seated properly. If there
are any fuse covers, ensure that they are closed.
Note: Not all PXE devices have overcurrent protectors.
Preparing the Installation Site
1. Make sure the installation area is clean and free of extreme
temperatures and humidity.
Note: If necessary, contact Raritan Technical Support for the
maximum operating temperature for your model. See Maximum
Ambient Operating Temperature
(on page 396).
2. Allow sufficient space around the PXE device for cabling and outlet
connections.
3. Review
Safety Instructions (on page iii) listed in this User Guide.

Filling Out the Equipment Setup Worksheet
An Equipment Setup Worksheet is provided in this User Guide. See
Equipment Setup Worksheet (on page 398). Use this worksheet to
record the model, serial number, and use of each IT device connected to
the PDU.
As you add and remove devices, keep the worksheet up-to-date.
Checking the Branch Circuit Rating
The rating of the branch circuit supplying power to the PDU shall be in
accordance with national and local electrical codes.
