The HPE Aruba Networking CX 6405 v2 (R0X26C) is part of the modular CX 6400 series, a high-capacity switch built for aggregation and campus core roles, running the modern AOS-CX operating system with full Layer 2 and Layer 3. Its modular line-card design means the port count, speeds and PoE depend on the cards fitted, so it is configured to the deployment rather than sold as a fixed box.

VSX high availability with redundant control planes, BGP/EVPN/VXLAN routing, and support for 100GbE uplinks enable resilient core switching for large multi-building enterprise networks.
Up to 480 Smart Rate PoE ports with 60W per port and 28,880W total PoE capacity power high-density access point deployments, IoT devices, and IP phones across enterprise campuses.
EVPN, VXLAN, and MPLS support with large TCAM sizes enable cloud-scale multi-tenant networking, service chaining, and dynamic network segmentation for carrier and cloud operators.
28 Tbps non-blocking bandwidth and wire-speed forwarding across all ports simultaneously support bandwidth-intensive HPC applications, scientific computing, and parallel processing environments.
Modular design with VSX live upgrades and redundant components enables zero-downtime maintenance and carrier-class availability for mission-critical branch office network aggregation.
Aggregation and campus core duty. It is a modular Layer 3 switch running AOS-CX, so it aggregates access switches and routes between VLANs rather than sitting at the desk edge.
It depends on the line cards fitted. The 6405 v2 is a 5-slot modular chassis, so port count and speed come from the modules you choose, across 1G, 10G, 25G and 100G options. Send us your target configuration and we will quote the exact build.
Yes, when fitted with PoE line cards. The 6400 series supports full-density PoE up to 60W per port with HPE Smart Rate multi-gigabit modules, so the PoE budget follows the modules and power supplies you choose.
Both, through AOS-CX. It performs full Layer 3 routing with MACsec encryption and dynamic segmentation, managed by CLI, web GUI, REST API or Aruba Central.
Both. We stock it new and recertified, and either condition carries our 30-day warranty.
