the all-new raritan px4 rack pdu

Our awarded and patented Cx outlet combines a C13 and C19 outlet into one flexible outlet.

With no additional parts needed, a C14 and C20 cable can be plugged into a single Cx outlet―delivering the ultimate flexibility in server installation, data center wide.

The Cx outlet’s innovative design allows a single Raritan PDU to be used for multiple applications, reducing the complexity and cost of the PDU selection process.

When server or storage refreshes occur, you will already have the right outlets in the right locations, ensuring your installations are flexible and ahead of shifting outlet requirements.

RamLock is a high-strength mechanical outlet locking and cord retention mechanism that secures C14 and C20 plugs to your PDU without requiring special cables, sleeves, or adapters.

Once a plug is inserted into an outlet with RamLock, the mechanism mechanically grips the body of the plug to keep it firmly locked in place.

RamLock’s spring-loaded lever eases unplugging with a one-handed “squeeze and pull” tactile release.

The advantages are clear. RamLock’s ease of use and locking confidence ensure high cord retention to maintain uptime.

Our newly designed 45-degree angled infeed promotes input power cord accessibility, reduces cord strain, and decreases the required PDU SKU count within your data center.

Now you don’t need to worry about selecting multiple PDU configurations, such as cords exiting from the front or the bottom of the device. The 45-degree angled infeed has you covered.

No matter where you feed the cabinet’s power, a single Raritan rack PDU designed with the 45-degree angled infeed simplifies your deployments.

Most data center power applications require three-phase power to deliver enough power density to support today’s heavy workloads.

To better facilitate the use of three-phase power, the alternating branch outlet technology built into Raritan rack PDUs, groups outlets into branches on a repeating and easily distinguishable pattern over the entire length of the PDU.

Alternating branch power notably simplifies load balancing and the power distributed from the PDU. When installing equipment, select the next branch on the PDU to simplify device installation, keeping patch cables shorter and away from the airflow path, and lessen out-of-balance loads that can cause heating in the neutral current line.

Certain custom Raritan PX4 three-phase models feature alternating power phases on a per-outlet basis rather than per-branch.

Raritan’s rack PDUs monitor multiple power metrics in real-time to efficiently use power resources and avoid downtime brought on by power quality fluctuations or overloaded circuits.

Raritan advanced metering features provide detailed and granular power utilization data through continuous AC sampling of several power parameters, including neutral voltage and current dips, swells, and harmonic distortion.

Minimum, maximum, and average measurements are captured with 0.5% metering accuracy. Metering measurements are retrievable using Xerus firmware, SNMP, or JSON APIs or in conjunction with DCIM or BMS software.

Current and voltage total harmonic distortion is now measured at the infeed power to the PDU and at the PDU’s outlets.

For example, Harmonics are typically created by a server’s switched mode power supply and are often present at the PDU’s outlets load. They can disrupt power quality, leading to increased electrical usage and power fluctuations, and can indicate a problem in the server’s power supply.

Improve uptime by conducting continuous power quality measurements―like harmonics monitoring and alerting. With this feature, you can monitor for harmonic events, voltage dips and swells, crest factor, and more on the power being fed to the PDU or distributed to the PDU’s outlets or load.

Raritan rack PDU harmonic measurements elevate your cabinet-level power quality monitoring and help to prevent problems before they occur.

When monitoring power information on Raritan rack PDUs, the peak and minimum/maximum power measurements are stored for power metrics, including Current, Voltage, Line Frequency, Active Power, Total Harmonic Distortion, and more.

These measurements help identify power quality problems to determine normal loads and failover ratings so that informed decisions can be made. You will know which cabinets have adequate power available for new devices so that you do not exceed the overall power load, avoiding power-related problems before they occur.

Peak, minimum and maximum measurements are updated every second, can be stored, and can be reset at any time.

When a circuit breaker trips on your rack PDU, you need to know why and fast.

With enhanced circuit breaker trip forensics, the PDU now identifies the specific outlet that caused a trip, and therefore the device, saving time when investigating and resolving issues.

When a PDU’s breaker trips, now capture the current and voltage waveform at the suspected outlet to help determine the root cause of the problem.

Waveform captures can be automated based on specific events or initiated on-demand through the Raritan web Interface or JSON APIs.

Xerus’ secure, reliable technology platform increases the lifecycle of your PDUs by facilitating power management and monitoring, environmental monitoring, capacity planning, asset governance, physical access control, and more.

The Xerus Technology Platform combines hardware and software technologies embedded in Raritan power solutions. It delivers high compute power, power quality measurement metrics including harmonic distortion and waveform capture, advanced alerting and alarms, security, a true hot-swappable network card, and support for environmental sensor options, all to gain complete visibility into your power chain.

The platform ensures compatibility with your data center infrastructure through flexible software architecture. You can easily integrate PDU features and data into your data center tools and applications through SNMP and a RESTful API―including a new RESTful Redfish API―then leverage Lua Scripting to customize data output.

Xerus’s interoperability also extends through JSON-RPC SDKs for Perl, Python, JavaScript, Curl, and more.
