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

Overview

The Aruba R0X43C is an expansion module designed for Aruba 6400 Series switches, providing twenty-four 10 Gb SFP+ ports and four 50 Gb SFP56 ports to increase network bandwidth. This module supports high-density connectivity for environments where user counts, virtual machines, or data streams demand more capacity. Its Gen7 ASIC architecture ensures wire-speed forwarding, allowing all ports to operate simultaneously without bottlenecks, which is essential for maintaining low latency in enterprise and data center networks.

Ideal for enterprise campuses, it efficiently handles traffic from access points, cameras, and IoT devices, while in data centers it supports virtualization clusters, backup operations, and high-speed storage replication. The open SFP cages offer flexibility to use fiber or direct-attach copper cables based on distance and budget needs.

Key features

Connectivity and compatibility

The module’s open SFP cages allow network teams to select fiber or direct-attach copper cables on a per-port basis, providing flexibility to match link distance and budget constraints. This adaptability makes it suitable for a variety of network setups, from campus environments to data centers, ensuring smooth integration with existing infrastructure.

• Supports both fiber optic and direct-attach copper connections
• Fits seamlessly into Aruba 6400 Series chassis for centralized management

Installation and setup

Installation is straightforward, requiring only sliding the module into an available slot on the Aruba 6400 chassis and securing it with captive screws. This design eliminates the need for additional mounting hardware and keeps the rack setup clean and efficient. Once installed, the module works with Aruba’s configuration tools to quickly apply network policies and monitor performance.

Ideal uses and environments

This expansion module is well suited to enterprise campuses that need to support large numbers of wireless access points, security cameras, or IoT devices without creating network bottlenecks. It also fits data center environments where virtualization clusters, backup traffic, and storage replication demand high-speed, reliable connections. Network administrators looking to scale bandwidth within a single chassis while maintaining centralized control will find this module a strong choice.
