Legrand Raritan iX Rack-PDU 1U with 12xC13 / 4xHDOT Cx, 1-phase 100-240V 20A, Input Metered, SecureLock (PX4-1256CR-C8E8A0)

Why an intelligent Rack-PDU with Input Metering is indispensable in the data center

In modern data centers and server rooms a simple power distribution no longer suffices. Anyone who wants to operate their IT infrastructure efficiently and securely needs an intelligent rack PDU with precise energy measurement, remote monitoring and reliable load management. The Legrand Raritan iX Rack-PDU 1U (PX4-1256CR-C8E8A0) addresses precisely this: with billing-grade metering (class 0.5), branch circuit monitoring and full remote management via Gigabit Ethernet it provides all the tools for transparent, resilient operation. Thanks to SecureLock locking and a hot-swappable controller it can also be serviced while running — without interrupting the power supply. The precise measurement of voltage, current, real power, apparent power, energy and power factor forms the basis for informed decisions in capacity management and energy cost analysis. In addition, the PDU monitors harmonics, voltage sags, neutral current and crest factor — parameters that are decisive for assessing power quality in the data center.

What advantages does horizontal 1U mounting offer compared to vertical PDUs?

The horizontal 1U rack PDU is particularly suitable for environments where rack space should be used optimally and a clear cable routing at a defined rack height is desired. Unlike vertical 0U PDUs, a 1U PDU can be flexibly positioned in any rack bay — ideal for standardized 19-inch racks in data centers, colocation environments and network cabinets. The Legrand Raritan PX4-1256CR-C8E8A0 combines the compact 1U form factor with 12 mixed outlets (8x C13, 4x HDOT Cx) and thus achieves maximum connection density in minimal space. The SecureLock locking secures each plug mechanically against accidental disconnection — a feature that provides a significant safety gain, especially in environments with frequent maintenance or tight spaces. By combining C13 and HDOT Cx outlets, both standard IT devices and higher-power components can be powered from a single PDU without additional adapters or power strips.

How does the Raritan iX PDU support energy management in the data center?

Efficient energy management starts with a reliable data basis. The Raritan PX4-1256CR-C8E8A0 continuously captures all relevant electrical parameters — from real and apparent power to power factor, voltage quality and harmonics. These data are available in real time for DCIM systems, monitoring platforms and capacity planning via Redfish API, SNMP v3, MODBUS-TCP and JSON-RPC. In addition, up to 8 PDUs can be combined via PDU Linking into a single unit — for a centralized overview of multiple racks or cabinets in the data center. Cascading of up to 32 PDUs over a single Ethernet port reduces the need for IP addresses and greatly simplifies network infrastructure. Environment sensors for temperature, humidity, airflow and other parameters extend monitoring beyond power alone and enable holistic infrastructure management. Automated provisioning via TFTP, DHCP or USB flash drives speeds up commissioning of new PDUs and minimizes manual configuration effort in the data center. The combination of precise energy measurement, power quality monitoring and extensive remote management capabilities makes the Legrand Raritan PX4-1256CR-C8E8A0 a future-proof investment for data center operators who want to professionally manage their power infrastructure while laying the foundation for sustainable growth and increasing requirements on availability and energy efficiency. The iOS and Android app additionally enables mobile access to all measurements and alarms — for maximum flexibility in day-to-day data center operations.
