Frequently Asked Questions
What chassis models are compatible with the HPE R0X43A expansion module? +
The R0X43A is specifically engineered for the Aruba CX 6400 Switch Series. It integrates seamlessly into the available slots of both the 5-slot and 10-slot chassis, providing high-density 10GbE connectivity that leverages the powerful AOS-CX operating system for modular enterprise networking environments.
Can the 4-port SFP56 interface on the R0X43A support speeds lower than 50Gbps? +
Yes, the SFP56 ports are designed for flexibility. While they offer native 50GbE performance, they are backward compatible with lower-speed SFP28 or SFP+ transceivers. This allows you to deploy the module in mixed-speed environments, providing a future-proof path for uplink or high-bandwidth server connectivity within your core or distribution layers.
Does the R0X43A support MACsec for hardware-based encryption? +
The Aruba CX 6400 series modules are designed for secure enterprise deployments. The R0X43A hardware architecture supports line-rate MACsec encryption, ensuring that data traversing your switch fabric remains secure at the physical layer without compromising the high-throughput performance required for demanding 10GbE and 50GbE networking tasks.
What is the primary use case for this 24-port SFP+ and 4-port SFP56 module? +
This module is ideal for high-density server aggregation and core-to-distribution switching where low latency is critical. By populating your Aruba CX 6400 chassis with this line card, you can consolidate large numbers of 10GbE server connections while reserving the high-bandwidth SFP56 ports for high-speed uplinks to the network core.
How does the R0X43A contribute to switch fabric reliability in the Aruba CX 6400? +
The module is designed for carrier-grade reliability within the modular CX 6400 framework. It supports hot-swapping and integrates with the chassis's redundant power and fan systems, ensuring that your critical network infrastructure maintains high availability even during routine maintenance or individual component failures.
Is the R0X43A managed via standard Aruba AOS-CX interfaces? +
Management of this module is fully integrated into the Aruba CX 6400 management plane. You can monitor port status, configure VLANs, and manage traffic flow using the standard AOS-CX CLI, Web UI, or Aruba NetEdit. It operates as a native extension of the switch fabric, simplifying your administrative workflow.
Are there specific transceiver requirements for the 10GbE SFP+ ports on this module? +
To ensure optimal performance and system stability, we recommend using genuine Aruba-branded SFP+ transceivers and direct-attach cables. While the ports are designed to be standards-compliant, using validated HPE/Aruba optics ensures that the link-state information and digital optical monitoring data are accurately reported to the switch management software.
How does the performance of the R0X43A compare to fixed-configuration 10GbE switches? +
Unlike fixed switches, the R0X43A provides a modular approach to scaling. It leverages the backplane capacity of the Aruba CX 6400 chassis, offering a non-blocking architecture that scales significantly better than standalone units. This modularity allows you to increase port density incrementally as your enterprise bandwidth requirements grow.
How can I request a bulk quote for multiple R0X43A modules for a large data center deployment? +
For large-scale infrastructure projects requiring multiple R0X43A units, contact our dedicated sales team directly. We specialize in enterprise-tier procurement and can provide customized bulk pricing quotes tailored to your specific project volume and deployment timeline, ensuring your data center build remains within budget.
