Introduction
The Lenovo zero-U (0U) Basic and 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 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) PDUs. (v1 and v2 models are identical).
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 Basic and 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, the Basic PDUs offer a cost-effective option to users who do not require intelligence. The Switched and Monitored PDUs also offer individual outlet remote monitoring and switching (on/off), which allow 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 two types of 0U PDUs 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.
- 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.
Basic PDUs
The Basic PDUs offer a cost-effective option to users who do not require intelligence. Premium hydraulic-magnetic circuit breakers operate reliably in high temperature environments.
The following tables provide the ordering part numbers for the Basic PDUs.
The following table shows the orderable part number, feature code and CTO (Machine Type/Model) for the v2 Basic PDU models.

- Reset button: Use this button to reset the PDU for communication purposes only. Resetting the PDU does not affect the outlets/loads.
- Interface Ports:
- USB-C port: Use the USB connection to upgrade firmware and configuration file download/upload.
- Ethernet ports: Use for redundancy and cascading (daisy chain)
- 1x Gigabit Ethernet (10/100/1000 Mbps)
- 1x (10/100 Mbps)
- Serial ports:
- Digital Sensor port 1: dual function - sensor or serial connectivity. Use this port to open a serial connection to the PDU from your laptop.
- Digital Sensor port 2: sensor connectivity
- Supports up to 10 physical sensors (optional sensors such as: door open/close, fluid spot leak detector, humidity, temperature available thru Enlogic vendor)
- Daisy chain port:
- 1x Gigabit Ethernet (10/100/1000 Mbps) port on PDU1 to 1x (10/100 Mbps) port on PDU2.
- Use ports to daisy chain two PDUs together. This setup enables multiple PDUs to connect over one Ethernet port. In daisy chain mode, up to 64 PDUs can be connected via one (1) IP address. This allows user to gather information and data of all daisy chained PDUs from the master PDU.
Figure 8. Daisy-chain PDU setup
RNA (Redundant Network Access) Functionality
- Enlogic RNA allows to secure the access of PDU data and statistics on two separate private networks.
- RNA is used with a redundant power delivery design including two rack PDUs for each IT rack. PDUs are used in RNA applications that must be of the same SKU.
The following is a sample of RNA connectivity
Browser interface
The PDU provides a graphical user interface that you can view from a web browser. Using a web browser, you can access and monitor the PDU power outlets and output devices remotely from a computer.
The following tasks can be performed though browser interface:
- Controls individual outlets (On/Off)
- Displays PDU current, watts, output power in VA, power factor, and frequency
- Displays outlet level voltage, power factor and cumulative KW hour output
- Sets outlet alarm thresholds
- Views temperature and humidity status where the PDU is located and set thresholds to trigger alarm notifications
- Views dry, humidity and temperature status
- Accesses a graphical historical view of PDU data for statistical trend analysis
- Views PDU Alarms
- Views Event/System Logs
Environment Probe
The optional PDU Environmental Temperature & Humidity sensor (part number 4XF7A93184) can be used to report local temperature and humidity values and make that information available to management tools. The EMP connects to the PDU via its NMC. The PDU Environmental Temperature & Humidity sensor is shown in the following figure.
Figure 10. Environmental Temperature & Humidity sensor
The Environmental Temperature & Humidity sensor has the following features:
- Shipped with 2 Meter cable and integrated magnet for easy mounting
- Hot pluggable for easy integration
- Temperature Measuring Range 0 to 65 °C
- Temperature Measuring Accuracy +/- 2 %
- Humidity Measuring Range 10-90% RH, Non-Condensing
- Humidity Measuring Accuracy +/- 5 %
- Can be extended with a standard Ethernet cable
Additional information. Using an Ethernet cable to extend the EMP has the following requirements / limitations :
- Requires: a cross-over Ethernet cable
- Supported cables: CAT 5E or CAT 6E 4Core cable
- Maximum length of the Ethernet cable that can be used: 30 m (98 ft)
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 monitoring and/or outlet switching? If so, then consider the switched and monitored PDUs described here. If not, consider the Basic PDUs described above as well.
- Do you require environmental monitoring capabilities? If so, then consider the switched and monitored PDUs described here. If not, consider the Basic PDUs described above as well.
- 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 nVent (CIS) site.
