Is this a Layer 3 switch?

Yes, it's a Lite Layer 3 fully managed stackable switch supporting static and RIP routing, ACLs, sFlow, and IPv6 with no software licensing. Robust Layer 2 features enhance segmentation and security in enterprise access networks.

What is the switching capacity and latency?

Switching capacity is 176 Gbps with up to 112 Mpps throughput. Latency measures <3.8 µs at 1000 Mbps and <1.6 µs at 10 Gbps, powered by dual-core ARM Cortex A9 at 1016 MHz, 1 GB DDR3 RAM, and 12.38 MB packet buffer for low-latency performance.

What form factor and management options are available?

It's a 1U rack-mountable fixed switch compatible with Aruba AirWave, IMC, and cloud-based Aruba Central. Zero Touch Provisioning simplifies deployment, making it suitable for branch offices and campuses with minimal on-site IT.

What processor and memory specs does it use?

Dual-core ARM Cortex A9 processor at 1016 MHz, 1 GB DDR3 SDRAM, 4 GB eMMC flash, and 12.38 MB packet buffer (4.5MB ingress/7.875MB egress). This ensures efficient handling of queue configurations and adaptive power for demanding applications.

Is it stackable and suitable for enterprise use?

Yes, as a fully managed stackable switch from the Aruba 2540 Series, it's designed for enterprise, SMB, and branch deployments with built-in 10GbE uplinks and advanced QoS for mobile-first digital workplaces.
