DESCRIPTION
NVIDIA MSN2410-CB2FC – SN2410 48 x SFP28 + 8 x QSFP28 Open Ethernet Switch (formerly Mellanox)
The MSN2410-CB2FC is an NVIDIA SN2410 series fixed-configuration Open Ethernet switch built on the NVIDIA Spectrum (Spectrum-1) ASIC, providing 48 x SFP28 + 8 x QSFP28 in a 1U form factor. It delivers 4 Tbps of switching throughput and processes up to 2.97 Bpps, backed by a 16 MB fully shared packet buffer. NVIDIA’s official ordering description: “NVIDIA Spectrum 25GbE/100GbE switch with Cumulus Linux, 48 SFP28 + 8 QSFP28 ports, 2 AC PSUs, x86 2-core, short depth”.
Key Features
Ports: 48 x SFP28 + 8 x QSFP28
Port speeds: 10/25GbE on SFP28 ports (per OPN speed class); up to 100GbE on QSFP28 ports
Throughput: 4 Tbps
Packet rate: 2.97 Bpps
Packet buffer: 16 MB, fully shared across all ports
Latency: 300ns cut-through
Software: Cumulus Linux factory designation – note: software licensing, subscription and support entitlements are not conveyed with refurbished hardware
Airflow: P2C (power-to-connector) – air intake at the power/fan (rear) side, exhaust at the connector (port) side (blue FRU handles/dots)
Power supplies: 2 hot-swappable PSUs (1+1 redundant), AC (DC on select OPN)
Dimensions (HxWxD): 1.72 x 17.24 x 15.5 in (43.9 x 438 x 394 mm), short depth
Part numbers: Legacy OPN MSN2410-CB2FC = NVIDIA 920-9N112-00F7-0C2 (same hardware)
Port Flexibility and Breakout
QSFP28 uplinks split to 4 x 25GbE / 4 x 10GbE or 2 x 50GbE with breakout cables. Actual modes depend on the installed network OS version and transceivers.
Spectrum Architecture
SN2410 systems are built on the NVIDIA Spectrum (Spectrum-1) switching ASIC with a fully shared, monolithic packet buffer – every port can draw on the entire buffer, which absorbs microbursts and many-to-one incast far better than segmented-buffer designs in the same class. The platform supports RoCE (RDMA over Converged Ethernet) for storage and AI east-west traffic, rich telemetry with NVIDIA What Just Happened (WJH) hardware-level visibility, and the Open Ethernet model: the same hardware runs multiple network operating systems, so the fabric is never locked to one vendor stack.
Deployment Scenarios
Server top-of-rack (ToR) access: dense SFP28 server connectivity with QSFP28 uplinks to the spine
Storage-heavy racks: RoCE-optimized forwarding for NVMe-oF and scale-out storage traffic
Brownfield 10G to 25G migrations: SFP28 ports serve existing 10GbE servers and 25GbE upgrades on the same switch
Choosing Among the Variants
SN2410 OPNs decode as follows: the letter before the airflow character sets the speed class (B = the lower speed build, C = 100GbE, V = 200GbE, W = 400GbE); F = P2C airflow (power-side intake, port-side exhaust) and R = C2P airflow (port-side intake, power-side exhaust); a trailing C = Cumulus Linux, a trailing O = ONIE only, and no trailing letter = NVIDIA Onyx. Important: NVIDIA’s F/R airflow letters are defined by intake side at the power side or connector side – do not assume they match other vendors’ F/R conventions. Match the airflow variant to your hot-aisle/cold-aisle layout and the software designation to your operations model; the underlying switch hardware within a speed class is otherwise identical.
Mellanox and NVIDIA Part Numbers
The SN2410 was designed by Mellanox Technologies, which NVIDIA acquired in 2020; the same platform has been sold under both the Mellanox and NVIDIA names. It carries two interchangeable part numbers: the original Mellanox-style OPN MSN2410-CB2FC and the newer NVIDIA number 920-9N112-00F7-0C2 – both identify exactly the same hardware. Listings and documentation referring to a “Mellanox SN2410” and an “NVIDIA SN2410” describe the same switch.
Frequently Asked Questions
Is the MSN2410-CB2FC a Mellanox switch or an NVIDIA switch?
Both names refer to the same product. The SN2410 platform was developed by Mellanox, which NVIDIA acquired in 2020. The OPN MSN2410-CB2FC and the NVIDIA part number 920-9N112-00F7-0C2 identify identical hardware.
What software does the MSN2410-CB2FC run?
This OPN designates a factory build with Cumulus Linux, NVIDIA’s Linux-native network OS for automation-driven fabrics. As with all refurbished hardware, software licensing, subscription and support entitlements are not conveyed with refurbished hardware – units are tested on original-spec firmware, factory reset, and configuration wiped. Confirm any OS licensing or support requirements with NVIDIA for your production environment.
What is the airflow direction of the MSN2410-CB2FC?
The MSN2410-CB2FC is the P2C (power-to-connector) variant: air intake at the power/fan (rear) side, exhaust at the connector (port) side. NVIDIA marks this direction with blue handles or dots on the fan and PSU modules. All FRUs in one chassis must share the same airflow direction.
What breakout options does the MSN2410-CB2FC support?
QSFP28 uplinks split to 4 x 25GbE / 4 x 10GbE or 2 x 50GbE with breakout cables.
Is the refurbished MSN2410-CB2FC tested before shipping?
Yes. BrightStar Systems inspects and tests every unit on original-spec firmware, performs a factory reset and configuration wipe, and backs it with warranty (1 year end-user / 90 days reseller).
