What is the switching performance?

Switching capacity is 256 Gbps with throughput of 190 Mpps or 211 Mpps, and latency of 4.02 µs for store-and-forward 64-byte packets or <5 µs. It handles wire-speed L2/L3 traffic efficiently for high-density deployments.

What are the memory specifications?

Features 2048 MB SDRAM for processing, 512 MB flash for storage, and 8 MB packet buffer. This configuration supports large MAC (32000 entries) and routing (16000 IPv4) tables without performance loss.

Is it rack-mountable and what are dimensions?

Yes, 1U rack-mountable form factor with dimensions 42.7 x 4.36 cm (width x height) and weight of 18.74 lb (8.5 kg). Ideal for space-constrained data centers.

What power options are available?

Dual power-supply slots with 1 minimum required (ordered separately); supports redundant hot-swappable supplies for high availability in enterprise environments.

What is the product type and use case?

Layer 3 stackable Ethernet switch for enterprise core, distribution, or data center edge. Offers full L2/L3 IPv4/IPv6 with OAA module compatibility for flexible services.
