We will continue sales of most PX3 models, including providing support on PX3 models that are not discontinued or end-of-life. Customers will be given advanced notice before any changes to sales or support. To learn more about Raritan’s discontinued and end-of-life power distribution products and policies, please see the Power EOL Page.
Yes. Cascading is the physical connectivity of rack PDUs, connecting rack PDUs via the Ethernet port or USB A/B port (e.g., physically chaining PDU 1’s USB-A port (the Primary PDU) to PDU 2’s USB-B port (the Expansion PDU)) across multiple racks/cabinets. You need to define 1 PDU as the Primary PDU, then you can cascade 31 additional Expansion PDUs from the Primary, totaling 32 PDUs in the cascade/daisy chain.
There are 2 different types of cascading modes to choose from after physically connecting the PDUs, they are bridging mode and port forwarding mode. Bridging mode allows for each PDU in the chain to have a separate IP address. Port forwarding mode reduces the number of IP addresses, where every PDU in the chain has the same IP address. That means 1 IP address for up to 32 PDUs, where each PDU in the chain gets assigned its own port number. Cascading is the physical connectivity of devices that reduces the number of network ports used on network switches and reduces the number of IP addresses required.
Yes. Linking is the logical connectivity of devices, using the PDU Link port within the same rack/cabinet. Where you can link a single Primary PDU with multiple Link PDUs for more efficient power management. Linking connects multiple PDUs, where PDU 1 is defined as the Primary PDU and then you can link up to 7 additional PDUs, called Link PDUs, totalling 8 PDUs. Once PDUs are linked, you can log into Primary PDU and use one single interface to then select any PDU that is linked and see the data collected.
No. All devices in the chain should be the same models and must be running the same firmware version.
With the known admin password, open the Web UI then go to > Maintenance > Unit Reset > Reset to Factory Defaults or CLI command reset factory defaults
PX4 controllers have a PDU Link port that also provides power sharing. Link PDUs downstream from the Primary PDU that are cascaded with the Link port will provide controller power redundancy. If the source power to the Primary PDU is lost, the controller will remain powered on to send configured notifications via power sharing from connected link units.
The PX4 does not have a feature port, so the connection to a Power CIM peer can be achieved through a USB dongle (DSER-PWR-USB-G4 and DKX3-PWR-USB-G4) and the USB-A port. You can use the SNMP protocol to communicate with the Raritan KVM or serial devices. Note: Power CIM peer stands for either a Raritan KVM switch (KX2, KX3 via D2CIM-PWR) or a Raritan serial switch (SX, KSX2).
Yes. The PX4 controller will display a visual and sonic alarm when the breaker trips and the branch associated outlets will flash multi-color. These alarms are also logged in the PDU event log and sent via SNMP traps and SMTP notifications when configured in the PDU Event Rule setting.
The PX4 has been tested and approved for safe and reliable operation in environments from 0°C to 60°C / 32°F to 140°F.
Yes. The PX4 is built on the Xerus Technology Platform, Intelligent PDUs provide an SNMP MIB or open API that interoperates with third-party software such as DCIM or BMS.
The iX Controller is hot-swappable:
The PX4 supports daisy-chained DX2-series SmartSensors, each with the ability to send SNMP-based alerts and email notifications.
Yes. Custom options include:
It displays the PDU's configuration and allows easy access to all power and monitoring data locally at the rack; the display rotates to a vertical or horizontal orientation; and the display changes color to indicate an event or alarm notification such as circuit breaker trips, alarms/alerts, and other user-defined configurations.
Alternating Branch is standard on Raritan PX4 PDUs. Alternating Branch is a traditional power distribution method to distribute alternating phase power to a group of outlets, or a branch of outlets. One branch is used for each phased pair. This means that a minimum of three branches are required to fully distribute the available power. An equal quantity of outlets is used on each branch. By dedicating a branch for each phased pair, the end-user reduces the risk of overloading any single phase.
