Product Description
The HP R0X42A is a high-performance LAN Expansion Module engineered for the HP 6400 series modular switch platform. This module is designed to deliver dense, high-speed connectivity, making it ideal for environments that require significant bandwidth and a large number of 10 Gigabit Ethernet connections. It features twenty-four 10GBase-T RJ-45 ports, providing robust and widely compatible connectivity for servers, storage devices, and high-performance workstations. Complementing the extensive 10GBase-T ports, the R0X41A includes four SFP56 ports. These versatile ports allow for flexible network expansion, enabling high-speed uplinks to core switches, connections to other network devices, or the use of various transceiver types to meet specific distance and media requirements. The SFP56 interface ensures that the module can adapt to diverse network topologies and future-proofing needs. This expansion module is a critical component for enterprise-level networks that demand high throughput and port density. By integrating the R0X42A into an HP 6400 series switch, organizations can build out robust network infrastructures capable of supporting data-intensive applications, virtualization, and high-speed data center operations. Its design emphasizes ease of deployment and integration within the modular switch chassis, providing a scalable solution for evolving network demands.
