Chapter 1. Introduction
The IBM®Distributed Power Interconnect 100-127V Rack Power Distribution Unit
(PDU) comes with a fixed power cord and enables you to connect up to six devices to
a single dedicated power source. The Universal Rack PDU comes with a country or
region-specific power cord and enables you to connect up to seven devices to a single
dedicated power source, such as an electrical outlet, a Front-end PDU, or an
uninterruptible power supply.
The latest version of this publication is available from the IBM Web site. Go to
http://www.ibm.com/ and click Support & downloads. In the Technical Support
keyword search field, type "DPI PDU" and click Go. The latest version of this
publication will be in the list of publications displayed.
The 100-127V and Universal Rack PDUs have a green LED to indicate when power is
supplied to the outlets. The LED lights when the Rack PDU is connected to a power
source and the circuit breaker is in the On position.
Note: The illustrations in this documentation might differ slightly from your hardware.
You can install PDUs vertically in the side of a rack cabinet, or horizontally within 1U of
EIA mounting space in a rack cabinet. The mounting hardware that comes with this
option enables you to install two PDUs beside each other in the same mounting space
within a rack cabinet.
The following parts come with your Rack PDU:
• 100-127V Rack PDU with fixed power cord OR Universal Rack PDU with a
country or region-specific power cord
Notes:
1. In the United States, the Universal Rack PDU comes with both a low-voltage
and a high-voltage power cord.
2. Universal Rack PDUs also come with one IEC 320-C19 to IEC 320-C20
power cable for connecting the Rack PDU to a Front-end PDU.

Chapter 2. Installing PDUs with the vertical-mounting plate
Complete the following steps to install 100-127V or Universal Rack PDUs in the side
of a rack cabinet, using the vertical-mounting plate. The illustrations in this chapter
show a Universal Rack PDU, but the steps for installing a 100-127V Rack PDU are the
same.
Note: The mounting holes on upper and lower side braces in a rack side
compartment must be between 48.6 cm (19.1 in.) and 56.9 cm (22.4 in.) apart. If your
rack cabinet has movable side braces, refer to your rack cabinet documentation for
information about relocating your side braces if they are not already spaced for this
installation.
1. Refer to your rack cabinet documentation for additional information.
Note: Removing the rack doors and side panels might make installing PDUs
easier.
2. Verify that the circuit-breaker switch is in the Off position before installing a Rack
PDU.
3. Attach a Rack PDU to the vertical-mounting plate with two M3x5 screws that come
with the Rack PDU. Make sure that the countersink holes in the vertical-mounting
plate are facing away from the Rack PDU.
4. If you have a second Rack PDU to install, install it on the vertical-mounting plate
with two M3x5 screws that come with the second Rack PDU.
