What is the switching performance?

Switching capacity is 6.4 Tbps (3.2 Tbps ingress/egress), with 2000 Mpps forwarding rate, 800 ns average latency, and 32MB packet buffers per ASIC. This ensures line-rate performance for high-throughput datacenter spine applications.

What power and cooling options are available?

Dual modular 750W AC PSUs provide redundancy; back-to-front airflow via 6 fan modules with one-fan redundancy. Max consumption 461W (fans high, full load), typical 215W; operates 0-45°C at sea level with 52 dB(A) noise.

What are the physical dimensions and weight?

Dimensions: 4.34 cm H x 43.96 cm W x 56.97 cm D (1U rack-mount). Weight: 9.7 kg unpackaged with two AC PSUs, 15.83 kg packaged; base unit 7.37 kg. Includes four-post rack kit.

What processor and memory specs?

Equipped with 8-core 2.2 GHz CPU, 16GB DDR4 ECC memory, 128GB SSD, and 4GB eMMC flash. This configuration supports advanced networking features, telemetry, and secure boot in demanding environments.

What is the MTBF and reliability?

MTBF is 476,814 hours at 25°C, with redundant PSUs and fans. Supports front/back airflow options and operates reliably up to 3000m altitude, ideal for enterprise datacenter deployments.
