Lenovo 0U Switched and Monitored PDUs User Guide

Product Guide

The Lenovo zero-U (0U) Switched and 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 42 outlets. 0U PDUs are designed to be installed vertically in the rear channel or side pockets 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 0U Switched and Monitored PDUs.

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 Switched and 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, these PDUs also offer individual outlet remote monitoring and switching (on/off), which allows for remote power sequencing 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.

There are three types of PDUs available from Lenovo: basic, monitored, and switched & monitored. The PDUs covered in this document are of the switched & monitored type.

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: provides the same benefits as a Basic PDU, but adds additional advanced PDU power monitoring down to the load group. This enables businesses to have a cross-platform racklevel power and thermal view for trending analysis to improve power management
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). To understand this, use the Power Configurator tool to determine the hardware’s overall power usage. Download the Power Configurator from http://support.lenovo.com/au/en/documents/LNVO-PWRCONF.

Likewise, to avoid over sizing or under sizing PDUs it is also important to understand the PDU capabilities and capacities.

Consider the following for capabilities:

Do you require monitoring and/or outlet switching? If so, then consider the switched and monitored PDUs described here. If not, consider the Basic PDUs described at at http://lenovopress.com/lp0576.
Do you require environmental monitoring capabilities? If so, then consider the switched and monitored PDUs described here. If not, consider the Basic PDUs described at at http://lenovopress.com/lp0576.
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, see the Lenovo PDU Technical Reference (International or North American version), available from: http://support.lenovo.com/documents/lnvo-powinf
