CX 6400 24‑Port SFP+ and 4‑Port SFP56 Expansion Module

The R0X43A is a high-density Expansion Module designed to enhance connectivity and uplink versatility within the CX 6400 chassisOffering 24 SFP+ ports (capable of 100 Mb/s, 1 Gb/s, or 10 Gb/s) and 4 SFP56 ports (supporting up to 50 Gb/s), this module delivers flexible, high-throughput networking for modern enterprise environments. Its plug-in form factor provides seamless integration and expansion without disrupting chassis operations, making it ideal for scaling Layer 2/3 deployments in data centers, campuses, and large enterprise infrastructures requiring both fibre-based port capacity and high-speed uplinks.

Features

This plug-in module installs into the expansion slots of the modular CX 6400 chassis, instantly adding 24 SFP+ fiber ports for access or aggregation layers and 4 high-speed SFP56 uplink ports compatible with 1/10/25/50 GbE data rates. The combined throughput capability reaches up to 50 GBps per module, ensuring high-density port scalability and bandwidth flexibility.

Advanced Options

Once installed, the module is automatically managed via the chassis operating system, allowing uniform provisioning, ACL enforcement, VLAN segmentation, and dynamic routing without manual configuration. Hot-swappable and plug‑and‑play capable, it supports live hardware upgrades and capacity scaling without traffic disruption.
