What is the switching performance?

The switch provides 192 Gbps non-blocking capacity with latency under 5 microseconds for 64-byte frames, enabling line-rate L2/L3 switching. It supports jumbo frames up to 9,252 bytes and wire-speed 1/10GbE for data center applications without bottlenecks.

What is the form factor and redundancy?

1RU rack-mount design with redundant hot-swappable power supplies (AC/DC) and fans. Dual airflow options (front-to-back or back-to-front) suit hot/cold aisle setups, ensuring high availability in enterprise environments with 130W max power.

Yes, up to 8 units via 12Gbps stacking modules in the 4 SFP+ slots, managed as a single logical switch. This simplifies scaling and administration for large deployments while maintaining low latency and full fabric performance.

What Ethernet speeds are supported?

1 Gigabit Ethernet on 48 ports (44x copper RJ45, 4x SFP) with 10GbE via 4x SFP+ expansion slots. Delivers wire-speed non-blocking switching for mixed 1/10GbE environments in data centers.

Is it suitable for data centers?

Optimized as ToR switch with non-blocking architecture, low latency <5μs, and features like redundant components and low 130W power. Ideal for high-performance edge networking with virtualization support.
