DESCRIPTION
NVIDIA MSN2201-CB2FC – SN2201 48 x RJ45 1GbE + 4 x QSFP28 100GbE Open Ethernet Switch (formerly Mellanox)
The MSN2201-CB2FC is an NVIDIA SN2201 series fixed-configuration Open Ethernet switch built on the NVIDIA Spectrum (Spectrum-1) ASIC, providing 48 x RJ45 1GbE + 4 x QSFP28 100GbE in a 1U form factor. It delivers 448 Gbps of switching throughput and processes up to 667 Mpps. NVIDIA’s official ordering description: “NVIDIA Spectrum based 1GBase-T/100GbE 1U Open Ethernet switch with Cumulus Linux, 48 RJ45 and 4 QSFP28 ports, dual AC PSUs, x86 CPU, short depth”.
Key Features
Ports: 48 x RJ45 1GbE + 4 x QSFP28 100GbE
Port speeds: 10/100/1000Mbase-T on RJ45 ports; 1/10/25/40/50/56/100GbE per QSFP28 port
Throughput: 448 Gbps
Packet rate: 667 Mpps
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 AC PSUs (1+1 redundant)
Dimensions (HxWxD): 1.72 x 16.84 x 17 in (43.9 x 428 x 432 mm), short depth
Part numbers: Legacy OPN MSN2201-CB2FC = NVIDIA 920-9N110-00F1-0C0 (same hardware)
Port Flexibility and Breakout
QSFP28 uplinks support 100GbE down to 1GbE speeds including breakout modes (50/40/25/10GbE). Actual modes depend on the installed network OS version and transceivers.
Spectrum Architecture
SN2201 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
1GbE campus and office access: 48 x RJ45 ports with high-bandwidth 100GbE uplinks
Out-of-band management networks: dense 1GbE copper for data center OOB with modern uplink speeds
PoE-free industrial/branch access: enterprise-class Spectrum forwarding at the 1GbE edge
Choosing Among the Variants
SN2201 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 SN2201 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 MSN2201-CB2FC and the newer NVIDIA number 920-9N110-00F1-0C0 – both identify exactly the same hardware. Listings and documentation referring to a “Mellanox SN2201” and an “NVIDIA SN2201” describe the same switch.
Frequently Asked Questions
Is the MSN2201-CB2FC a Mellanox switch or an NVIDIA switch?
Both names refer to the same product. The SN2201 platform was developed by Mellanox, which NVIDIA acquired in 2020. The OPN MSN2201-CB2FC and the NVIDIA part number 920-9N110-00F1-0C0 identify identical hardware.
What software does the MSN2201-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 MSN2201-CB2FC?
The MSN2201-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 MSN2201-CB2FC support?
QSFP28 uplinks support 100GbE down to 1GbE speeds including breakout modes (50/40/25/10GbE).
Is the refurbished MSN2201-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).
