Simplify Global Deployments Using a Universal-Input Rack PDU

Choosing a power distribution unit (PDU) for a server rack might seem straightforward. But what if you want a single PDU that can serve multiple regions and support many rack configurations?

For example, on the input side, designers working on global deployments need to accommodate a wide range of power architectures. This can be a problem for pre-integrated rack builders who want a universal chassis that can be deployed worldwide without worrying about different voltages or plug types.

There is a similar problem on the output side. Racks increasingly mix high-power gear with standard IT equipment. Accommodating these unpredictable combinations can be a challenge for system integrators, multinationals, and other organizations that want to standardize on a single PDU to simplify supply chain and inventory management.

Finally, PDUs play a critical role in system management. Adding metering and monitoring features to a PDU provides valuable benefits, but doing so can also create security vulnerabilities.

Introducing the UPDU G4, a rack PDU with a universal input

Tripp Lite by Eaton created the UPDU G4, a family of universal PDUs (UPDUs) designed to address these challenges head-on. It provides a single solution for diverse data center needs by combining global electrical compatibility with versatile C39 outlets and secure management capabilities.

The standout feature of the UPDU G4 is input flexibility. It accommodates single- and three-phase architectures in 208 volt and 415/240 volt environments for racks requiring up to 23 kilowatts (kW).

The input flexibility is enabled by detachable input cables, which are sold separately. Eaton offers 17 input cables with 15 different plug types, allowing the UPDU G4 to be deployed anywhere in the world by simply selecting the appropriate cable.

Flexibility is also a hallmark on the output side. The UPDU G4 supports up to 42 outlets, with a mix of:

• C13 outlets, which accept the C14 plugs used by most IT gear
• C39 outlets, which accept both higher-power C20 plugs and traditional C14 plugs

Finally, the UPDU G4 family includes models that support per-outlet metering, monitoring, and switching. These features are backed by strong cybersecurity measures, including chain-of-trust encryption and secure firmware boot, ensuring the PDU is not a weak point on the network.

Sophisticated remote management for rack PDUs

The EVMAGU23X (Figure 1) illustrates the capabilities of the UPDU G4 lineup. Measuring 72.00 × 2.00 × 2.56 inches (in.) (182.88 × 5.08 × 6.50 centimeters (cm)), this rack PDU provides 42 outlets in a slim design that fits neatly within a standard 42U rack.

The 42 outlets are split between 24 traditional C13 style and 18 high-retention C39 outlets. The outlets are grouped into six load banks, each with its own circuit breaker, to improve load balancing and organize connections in a crowded rack.

A key feature of the EVMAGU23X is its support for remote management. The PDU includes a hot-swappable gigabit network module (GNM) that enables each of the 42 outlets to be individually metered and switched. If a server hangs, for example, the EVMAGU23X can cycle power to that device without affecting the rest of the rack. To ensure this remote access does not introduce vulnerabilities, the module incorporates robust cybersecurity features, including zero-trust architecture and zero-touch provisioning.

Thanks to these capabilities, the EVMAGU23X can be managed through a web browser or integrated into data center infrastructure management (DCIM) systems. Users can also employ Eaton’s Brightlayer Data Centers suite management software or third-party tools. Together, these options reduce the need for on-site visits, a critical benefit for distributed data centers and edge networks.

A metered PDU for smaller racks

Eaton also offers 24-outlet variants for shorter racks. The EVMIGU23A-E (Figure 2), for example, measures 55.90 × 2.05 × 2.56 in. (141.98 × 5.08 × 6.50 cm) and fits into cabinets as small as 36U. To meet the needs of smaller enclosures, the EVMIGU23A-E provides 24 outlets, split evenly between C13 and C39 types.

Tripp Lite by Eaton produces both managed and metered UPDUs. The EVMIGU23A-E is an example of the latter: rather than supporting per-outlet management, it is limited to PDU-level monitoring with no ability to switch individual sockets. Among other applications, this streamlined approach is well-suited to colocation environments, where power consumption must be tracked for billing purposes, but remote switching is unnecessary.

As with other UPDU G4 models, these features are supported by the GNM and its robust security features. For system designers, this means they can deploy a mix of PDUs that meet different needs while maintaining a unified software interface.

Conclusion

Choosing a rack PDU that can serve any location and support a broad mix of rack configurations can simplify the design process and ease supply chain headaches. In addition, opting for a smart PDU that includes secure metering and monitoring streamlines ongoing system management. The Tripp Lite by Eaton UPDU G4 delivers both benefits, offering designers a global solution for complex data center power needs.
