Aruba 2920 Switch Series provides security, scalability, and ease of use for enterprise edge, SMB and branch office networks. These energy-efficient basic Layer 3 switches are easy to deploy and manage with advanced security and network management tools like Aruba ClearPass Policy Manager, Aruba AirWave, and cloud-based Aruba Central. The 2920 supports modular stacking (4 chassis), redundant power, 10GbE, RIP and Access OSPF routing, Tunneled node, PoE+, ACLs, sFlow, robust QoS and IPv6. It is optimized for Software-defined Networking (SDN) with OpenFlow support. This J9726A has 24 x 10/100/1000 ports including four that are combo dual purpose shared with SFP ports for fiber connectivity. Units also each have two available port module slots, a stacking module slot, and an available redundant power supply slot.
