Abstract
The Lenovo zero-U (0U) Monitored power distribution units (PDUs) are the ideal solutions when you need flexible, reliable, easy-to-deploy power distribution with branch circuit protection to minimize downtime. The 0U PDUs are designed to be installed vertically in a Lenovo rack, thereby not consuming any horizontal rack space.
This product guide provides essential presales information to understand the 0U Monitored PDUs and their key features, specifications, and compatibility. This guide is intended for technical specialists, sales specialists, sales engineers, IT architects, and other IT professionals who want to learn more about the 0U Monitored PDUs and consider their use in IT solutions.
Introduction
The Lenovo zero-U (0U) Monitored power distribution units (PDUs) are the ideal solutions when you need flexible, reliable, easy-to-deploy power distribution with branch circuit protection to minimize downtime. These rack-dense units distribute power to up to 48 outlets and 42 outlets. 0U PDUs are designed to be installed vertically in the rear channel of a Lenovo rack, thereby not consuming any horizontal rack space that otherwise be used by servers, storage and network switches (hence the term 0U).
The following figure displays the Lenovo zero-U (0U) Monitored PDU.

Did you know?
With ever growing power densities in today’s rack environments, it is all too easy to add load in the wrong place and trigger an overload event. The 0U Monitored PDU offerings can minimize this impact, providing the ability to quickly recover with resettable circuit breakers for each designated bank of receptacles, referred to as load groups. Breakers are color coded to the receptacles in a particular load group to aid in configuration, installation, and maintenance. Furthermore, the Monitored PDUs offer inlet and breaker metering, which allow for power distribution and further helping to prevent unintended PDU overloading.
Introduction to PDUs
A power distribution unit (PDU) is a highly reliable, multiple outlet power strip designed to consolidate line cords within the rack and distribute conditioned power from an uninterruptible power supply (UPS) or utility power to servers and other IT equipment. The PDU efficiently distributes power within the rack and provides fault-tolerant power redundancy for high availability requirements.
The following 0U PDUs are available from Lenovo. The PDUs covered in this document are:
- Basic PDUs: The simplest and most cost-effective power distribution. Available with various outlet configurations and line cord options to support different systems and load requirements.
- Monitored PDUs: Easily configured in minutes. Available with various outlet configurations and line cord options to support different systems and load requirements. Supporting various environmental sensors.
- Switched & monitored PDUs: These are advanced power management solutions, providing power monitoring at the outlet level, with increased accuracy at low amperages, for more precise views of power consumption down to the individual server level instead of at the consolidated load group. These PDUs also offer management via a web-based interface which includes individual outlet switching (on/off). Outlet switching allows for remote power sequencing and helps prevent unintended PDU overloading.

Selecting the right PDU
To avoid over sizing or under sizing power, it is important to understand the power requirements of the hardware that will be powered by the PDU(s). A useful tool to leverage to help calculate overall power usage is the Lenovo Capacity Planner (LCP) https://datacentersupport.lenovo.com/us/en/solutions/lnvo-lcp.
Likewise, to avoid over sizing it is also important to understand the PDU capabilities and capacities.
Consider the following for capabilities:
- Do you require environmental monitoring capabilities? If so, then consider the monitored PDUs described here.
- Does the PDU have the right type of power for your scenario? For example, 16A, 30A, 32A, 63A and single or three phase power?
- Does the PDU have enough of the correct type of outlets for your scenario?
Consider the following for capacities:
- Will each outlet be able to support the load being connected to it? For example, C13 outlets have a 10A limit.
- Will each load group be able to support the hardware being connected to it?
- Will each phase, where applicable, be able to support the hardware being connected to it?
- Is the overall power capacity of the PDU able to support the hardware being connected to it?
- Do you have enough PDUs to be N+N or N+1 redundancy if this is required?
For additional information on selecting the right PDU, load groups, phases, outlets, line cords, plugs and specifications, reference tables above and/or vendor's Raritan site.
