The NVIDIA Mellanox® MSN2010-CB2FC is a Spectrum-based 1U half-width Open Ethernet switch with 18× 25GbE SFP28 ports and 4× 100GbE QSFP28 ports, factory-loaded with Cumulus Linux. This is a fixed-configuration top-of-rack/leaf switch — not a modular spine chassis, an InfiniBand HDR/NDR fabric switch, or a 200/400GbE platform. Condition: Refurbished — full port-by-port link-up, PSU redundancy, and thermal cycling tested before dispatch.
Engineering Context. Built around the first-generation NVIDIA Spectrum ASIC, the MSN2010 supports cut-through forwarding with low, deterministic per-packet latency across all packet sizes. Native port speeds include 1/10/25GbE on the SFP28 array and 40/100GbE on the QSFP28 ports, with QSFP28 ports configurable for 4×25GbE breakout when paired with breakout DACs/AOCs. The half-width 1U chassis is designed for two-up rack mounting — a single 1U bay houses two MSN2010 units side-by-side. Two hot-swappable AC PSUs and field-replaceable fan trays provide redundancy.
Deployment & Use Cases. Top-of-rack leaf for hyperconverged infrastructure (Nutanix, vSAN), low-density storage racks, NVMe-oF aggregation, edge data center pods, and lab/PoC environments where compact form factor and Cumulus automation matter more than maximum port density.

- Condition: Refurbished — port, PSU, and thermal-cycle tested
Compatibility & Constraints. Compatible with NVIDIA/Mellanox QSFP28 and SFP28 DACs, AOCs, and transceivers; third-party optics may need vendor coding for full link-up. Half-width chassis requires the matching dual-mount rail kit for two-unit installation in a standard 1U bay (rail kit sold separately). Cumulus Linux subscription terms transfer with the chassis serial — confirm licensing before redeployment. P2C airflow only — verify rack airflow keying before install. Not compatible with 200/400GbE workloads (Spectrum-1 silicon caps at 100GbE) and not an InfiniBand switch.
Frequently Asked Questions (FAQ)
Q. What is the MSN2010-CB2FC?
The MSN2010-CB2FC is a compact Spectrum-based Open Ethernet switch with 18 ports at 25GbE and 4 uplinks at 100GbE, Cumulus Linux pre-loaded, 1U.
Q. Can Cumulus Linux be replaced with a different NOS?
Yes, since the platform is ONIE-based, but reinstalling requires a supported ONIE image.
Q. Will T.E.S IT-SOLUTIONS confirm the configuration of MSN2010-CB2FC before shipping?
Yes. T.E.S IT-SOLUTIONS (tes-itsolutions.com) bench-tests each unit where test topology is available, before dispatch from EU stock.
Why TES. T.E.S IT-SOLUTIONS stocks certified-refurbished NVIDIA Mellanox Spectrum and Quantum switches, ConnectX adapters, and matching DAC/AOC/transceiver inventory. Orders ship from EU stock with 1-3 business day handling, full port-and-PSU testing, and integration support.
