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.
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.
- 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
