What is the switching performance?

Switching fabric capacity is 1.28Tbps full-duplex (640Gbps half-duplex) with line-rate L2/L3 forwarding at 960Mpps and sub-700ns latency. The non-blocking architecture ensures full performance under load for high-performance computing environments.

What management features are available?

Supports open source ONIE for zero-touch installation of alternate network operating systems, enabling flexibility and reducing vendor lock-in. This is ideal for standardized datacenter deployments requiring custom NOS.

What are the power specifications?

Redundant hot-swappable AC power supplies (100-240V, 50/60Hz) with max 350W consumption, typical 220W, max current 4A at 100/120V or 2A at 200/240V, and 1194 BTU/h thermal output. Ensures high availability with efficient operation.

What are the physical and environmental specs?

1RU rack-mountable at 1.73 x 17.32 x 18.11 in (4.4 x 44 x 46 cm), 14.39 lbs (6.54 kg). Operates 32°F to 104°F (0-40°C), 10-85% RH; airflow options for I/O to PSU or reverse. Acoustic noise: 59.6 dBA at 23°C.

Is it suitable for hot/cold aisle datacenters?

Yes, offers I/O panel to PSU airflow or PSU to I/O panel airflow, plus redundant hot-swappable fans and PSUs. This flexibility supports diverse cooling setups while maintaining reliability in enterprise datacenters.
