Overview
With Aruba Central’s assistance, you can quickly set up remote branch sites with little or no IT support. A powerful Aruba ProVision ASIC provides performance, robust feature support, and value while allowing for future application programmability. The Aruba 2540 Switch Series offers a simple and cost-effective wired access solution that can be quickly configured using Zero Touch Provisioning. PoE+ models provide power to wireless APs, security cameras, and IoT devices via all access ports.
The 2540 has built-in 10 GbE uplinks, wire-speed backhaul bandwidth capacity, robust QoS, static and RIP routing, IPv6, and a limited lifetime warranty with no software licencing required.
