HPE Aruba R0X45C 6400 12-port 40/100GbE QSFP28 Module | Enterprise

Add high-density uplink capacity to Aruba 6400 switching with a 12-port QSFP28 expansion module. Supporting 40 GbE and 100 GbE connectivity, the R0X45C is designed for network teams that need more bandwidth at the aggregation or core edge without changing the switching platform. The value here is density. Twelve QSFP28 ports give architects room to build cleaner uplink topologies, reduce oversubscription, and align bandwidth with modern server, storage, and campus backbone demands. For organizations standardizing on Aruba 6400 systems, this module helps extend the platform’s role in high-throughput environments while keeping the hardware stack consistent. It is a practical fit for deployments where port count, speed, and modular growth all matter. Rather than forcing a larger refresh, the module lets you add capacity where it is needed most. That makes it well suited for enterprise networks that plan for growth, maintain spare capacity, and prefer modular expansion over disruptive replacement cycles.
