V E R V I E W
Modular PDUs have a unique modular architecture designed specifically for the dense data center customers who want to maximize their power
distribution and space efficiencies in the rack. This new modular design consists of two main building blocks, the Control Unit and the Extension Bar(s).
Available in 16A-40A current ratings, each unit comes with one Control Unit and up to four Extension Bars, offering up to 32 outlet receptacles (the 16A
model has two Extension Bars, and offers 16 outlets).
Providing easy accessibility and reduced cable clutter, the Modular PDUs offer you the flexibility to
easily mount your units in several different locations within the rack, without having to sacrifice valuable rack U-space.

Unique Modular Design Architecture
Modular PDUs have a unique modular design architecture. This “Building block” concept consists of two main parts, the Control Unit, and the Extension
Bar(s). The 24-40A mPDUs ship with one Control Unit and 4 Extension Bars. Each Control Unit is a single-phase unit that branches out into 4 single-
phase branch circuits. The Extension Bars can be plugged into the Control Unit, and can be mounted directly to the rack frame, spanning the entire length
of the rack.
Note: The new 16A Modular PDU model ships with one Control Unit (with 2 branch circuits) and two Extension Bars. This is the only model in the Modular
PDU family that has a detachable input power cord, allowing for increased flexibility, ease of use, and adaptability for country specific requirements.
The 24A and 32AmPDU models come with an attached input power cord, due to regulatory requirements for higher amperage devices. And the 40A
model has to be field wired. Higher amperage mPDUs offer more outlets, allow more equipment to be connected, and are especially suited to the
high-density server deployments.
Small Form Factor and Flexible Mounting Options
The Control Unit is zero-U or 1U rack mountable. And the Extension Bars mount directly to the rack-frame or the rack extension unit. With each Modular
PDU, you can get up to 32 outlet receptacles (except for the 16A and 40A models) in zero-U of rack space. And if you plan to mount two Modular PDUs in
one rack (typical configuration), you could get up to 64 output receptacles, without having to use any rack U-space.
Up to 32 Outlet Receptacles
Modular PDUs offer up to 32 outlet receptacles. Meaning, customers can plug-in as many as 32 power cords into one Modular PDU set. And if they were
to mount two such PDU sets, they have a total of 64 outlets! That means the Modular PDUs can support anywhere from a couple of servers in a rack to
up to 42 1U servers (IMPORTANT: Provided the total current load does not exceed the maximum allowable current draw of the PDU. To calculate server
current draw, please refer the Proliant Power calculator on
ActiveAnswers System Configurator tool).
Note: The 16A model has 16 outlets and the 40A model has 28 outlets, while the other models have 32 outlets.
Easy Installation
The installation process is quick and easy. Whether you choose to mount the Modular PDU in zero-U or 1U, all required mounting brackets, accessories,
and installation instructions are shipped with the product. The Extension Bars come with easy to use, snap-in brackets, which fit directly into the rack
frame of a HP 9000 and 10000 Series racks.
Note: Modular PDUs may be installed in most third-party racks in a 1U configuration (no zero-U mounting). To mount the Extension Bars in a rack other
than the HP 9000 and 10000 series racks, an optional kit PN 310777-B21 is offered. This kit allows mounting the Extension Bars in most third party
racks that use a standard EIA19
″
vertical rail.
