NVIDIA SN5000 Series – Spectrum-4 400/800GbE Switches for AI Fabrics
The SN5000 series is the Spectrum-4 generation and the Ethernet backbone of NVIDIA’s Spectrum-X AI networking platform: 51.2 Tbps of switching capacity, a 160 MB fully shared packet buffer, 33.3 Bpps packet rates, and 800GbE OSFP connectivity. These systems use NVIDIA-format 920- part numbers only (no Mellanox OPN equivalents). We also stock replacement PSUs, fan modules, and rail kits for this series.
Models
SN5600 – 64 x OSFP 800GbE + 1 x SFP28, 51.2 Tbps, 2U
SN5400 – 64 x QSFP56-DD 400GbE + 2 x SFP28, 25.6 Tbps, 2U
SN5600D – 800GbE with 48VDC busbar power
SN5610 – 800GbE with 4 AC PSUs and AMD EPYC management CPU
Airflow and Power Variants
SN5000 variants differ by airflow direction (C2P = port-side intake, red FRU handles; P2C = power-side intake, blue FRU handles), power architecture (AC PSUs vs 48VDC busbar on the D models), and management CPU. All ship with Cumulus Linux authentication designations; software licensing and subscription entitlements are not conveyed with refurbished hardware.
Refurbished SN5000 Series from BrightStar
Every unit is professionally inspected, tested on original-spec firmware, factory reset, and configuration wiped, with warranty included (1 year end-user / 90 days reseller). Software licensing and subscription entitlements are not conveyed with refurbished hardware. Switching of this class is typically project-priced – request a quote and our team will respond quickly with availability, airflow-variant guidance, and configuration help.
