Lenovo 1U Switched & Monitored 3-Phase PDUs

The 1U Switched and Monitored 3-Phase Power Distribution Units (PDUs) make it quick and simple to deploy, protect, and manage your high-availability rack environment. These space efficient and power dense PDUs were co-designed by Vertiv and Lenovo and come in the following 1U designs available to meet the requirements of your most power-demanding systems:

• 18x Combination outlets C13/C19 with 80A 3-phase Delta input - for USA, Canada, Japan
• 18x Combination outlets C13/C19 with 48A 3-phase Wye input (ETL certification) - for USA, Canada
• 12x Combination outlets C13/C19 with 60A 3-phase Delta input - for USA, Canada
• 12x Combination outlets C13/C19 with 32A 3-phase Wye input 1U - for all markets except Japan
• 18x Combination outlets C13/C19 with 48A 3-phase Wye input (CE certification) - for all markets except USA, Canada, Japan

The outlets (receptacles) on the PDUs give administrators the ability to remotely turn on, turn off, or reboot power at each outlet to power cycle unresponsive IT equipment. Outlet level monitoring gives a comprehensive view of outlet power usage via remote network access. They provide on and off functionality to allow for power sequencing and to help prevent unintended overloading. The following figure shows the PDU with 18 rear-facing outlets.

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 Switched and Monitored PDU offerings can minimize this impact, providing the ability to quickly recover with resettable circuit breakers for each designated bank of outlets (receptacles), referred to as circuits or load groups. Breakers are color coded to the outlets in a particular circuit 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.

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 rack-level 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.

The following figure shows the PDU with 12 rear-facing outlets.

The PDUs described in this product guide contain magnetic and hydraulic circuit breakers. The rating of the breakers can vary from their nominal rating based on the orientation of the PDU and consequently, the orientation of the circuit breakers within the PDU.

In particular, when a PDU is installed vertically in the side pocket of a rack, its rating can increase or decrease 10% from the nominal rating, depending on the orientation of the PDU in the side pocket. The following diagrams illustrate the rating for each breaker and the corresponding outlets protected by the breaker.

Note that if the PDU is installed horizontally in 1U slot of the rack, all of the breakers in the PDU are rated at their nominal rating of 18A.
