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 
• 18x Combination outlets C13/C19 with 48A 3-phase Wye input (ETL certification) 
• 12x Combination outlets C13/C19 with 60A 3-phase Delta input
• 12x Combination outlets C13/C19 with 32A 3-phase Wye input 1U
• 18x Combination outlets C13/C19 with 48A 3-phase Wye input (CE certification)

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.

Figure 2. Lenovo 1U Switched & Monitored 3-Phase PDU - 12-outlets model (attached line cord removed to show outlets)

The following tables provide the ordering part numbers and feature codes for the PDUs.

The PDUs have the following features

• 1U form factor allows for high-current deployments in a compact PDU. Can be installed vertically in the side pocket of a rack cabinet or horizontally at the rear of a rack space (1U rack unit)
• Combination C13/C19 outlets (receptacles) accommodate ever-changing rack power requirements with the flexibility to connect C14 or C20 plugs in the same outlet.
• Fully monitored and managed PDU including Residual Current Metering Type B
• Interchangeable Monitoring Device (IMD) is hot-swappable and includes ports for serial communication, environmental monitoring, and dual Gigabit Ethernet ports to simplify management of multiple PDUs with fault-tolerant daisy chaining or IP aggregation capabilities. One of these ports can be used to connect the IMD to an existing network or both ports can be used at the same time to connect one IMD to another in a daisy-chain configuration.
• Easily identify circuits with color-coded P-Lock tabs, streamlining circuit and phase balancing with alternating outlets.
• The use of P-Lock tabs on the outlets reduce the chance of accidental removal of a power cord from the PDU (P-Lock compatible cord sets required for locking feature)

• Comprehensive power management and flexible configuration
• Supported protocols: DHCP, HTTP, HTTPS, IPv4, IPv6, LDAP, NTP, RADIUS, RSTP, SSH, SMTP, SNMP (v1/v2c/v3), Syslog, TACACS+
• Detailed data-logging for statistical analysis and diagnostics
• Easy-to-use interface to display input and output status
• Event notification through SNMP trap or email alerts
• Reliable power distribution with local and remote power monitoring options offer quick access to critical power usage information to evaluate energy usage trends and maximize uptime.
• Remote monitoring of connected devices and sensors
• Easily accessible breakers
• Remotely reboot outlets to power cycle unresponsive IT equipment or increase runtime of critical equipment upon power failure with outlet-level control
• Monitor power consumption at the outlet-level for a detailed view of power distributed to specific equipment
• Local and remote input monitoring with accuracy of +/- 1% (ANSI C12.1 and IEC 62053-21 Standards)
• Detailed data logging for statistical analysis and diagnostics
• Management using SNMP v1, SNMP v2c, and SNMP v3

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.

Kratos PDUs with 9 Circuit Breakers

This section applies to the 18-outlet PDUs with 9 circuit breakers. The circuit breaker ratings are listed in the following table.

The table shows the different ratings based on the vertical orientation of the PDU. If the PDU is installed horizontally in a 1U slot of a rack, all circuit breakers are rated for 18A, regardless of whether the PDU AC cord is on the left or right.

The following figure shows the location of the circuit breakers and their ratings.

The PDUs include a local management panel, known as the Interchangeable Monitoring Device (IMD), which provides the interface and connectors to manage the PDU. The following figure shows the components and ports of the IMD.

Figure 6. Local management panel (IMD)

The components of the IMD management panel are as follows:

• Dual Ethernet Ports: The dual Ethernet ports act as a two-port Ethernet switch, allowing for multiple devices to be daisy-chained.
• Hard-Reboot Button: Pressing the hard-reboot button reboots the IMD. This acts as a power-cycle for the IMD; it does not change or remove any user information.
• Network Reset Button: Holding the network-reset button for 5 seconds during normal operation will restore the default IP address and reset the user accounts.
• Local Display: The local display shows the phase, line and circuit current values (in amperes).
• Display Buttons:
  • Back button: Press to decrement to previous channel. Also used to initiate a backup function.
  • Forward button: Press to increment to next channel. Also used to initiate a restore function
  • Center button: Toggle between scrolling and static display modes. Also used to initiate a reset function.
• Remote Sensor Port: RJ-12 port for connecting an environmental sensor.
• Serial Port: RS-232 via RJ-45 port.
• USB Port: USB port used to upload firmware, backup/restore device configuration or expand logging capacity via USB storage device. Provides up to 100mA power capacity for USB-connected devices.

The Environmental Sensor, part number 4M27A13686, is an optional device used to report local temperature and humidity values at its installed location and make that information available to the PDU. The Environmental Sensor connects to the PDU via the Remote Sensor port of the IMD of the PDU as shown in the Management panel section. The following figure shows the Environmental Sensor.
