Aruba 6400 24-Port SFP+ and 4-Port SFP56 v2 Module

The Aruba R0X43C is an expansion module built for Aruba 6400 Series switches that adds twenty-four SFP+ ports for 10 Gb links and four SFP56 ports for 50 Gb uplinks. It gives network teams the extra bandwidth they need when user counts, virtual machines, or data streams outgrow existing capacity.

In an enterprise campus, the module can move traffic from large groups of access points, cameras, or IoT devices without creating a bottleneck. Inside a data center, it supports demanding workloads such as virtualization clusters, backup traffic, and high-speed storage replication. Because the ports are open SFP cages, you can choose fiber or direct-attach copper on a link-by-link basis, matching distance and budget requirements.

The module runs on Aruba’s Gen7 ASIC architecture, which forwards packets at wire speed so every port can operate at full rate at the same time. This non-blocking design helps keep latency low and predictable, even during peak usage.

When paired with Aruba’s management and analytics tools, administrators can apply VLANs, quality-of-service rules, and security policies in a few clicks. Real-time monitoring and automated troubleshooting features shorten resolution times and reduce the need for manual command-line work.

Installation is straightforward: slide the module into an open slot on the 6400 Series chassis and secure it with the captive screws. The rack-friendly form factor measures 17.3 inches wide, 12.4 inches deep, and 1.7 inches high, and it weighs 6.5 lbs. By scaling inside the existing chassis, you avoid the expense and complexity of adding separate switches while keeping a single point of management.
