NVIDIA Mellanox® MSN2410-CB2FO Spectrum 25/100GbE 1U Open Ethernet Switch: This is a 1U fixed-configuration top-of-rack Ethernet switch built on the NVIDIA Mellanox Spectrum-1 ASIC, providing 48 SFP28 ports (10/25GbE) and 8 QSFP28 ports (40/100GbE). The MSN2410-CB2FO variant ships with ONIE bootloader (Open Network Install Environment) — no NOS pre-installed and P2C airflow. This is NOT a modular chassis switch and NOT an InfiniBand switch — it is a pure-Ethernet, fixed-port 1U appliance. This is a refurbished unit, fully tested by T.E.S IT-SOLUTIONS.
Engineering Context
The MSN2410 series is built on the Spectrum-1 switch ASIC, delivering 3.2 Tb/s of switching capacity and 2.38 Bpps forwarding throughput in a single 1U short-depth chassis. Port-to-port latency is approximately 300 ns under cut-through forwarding. The 8 QSFP28 uplinks each support 4×25GbE breakout, allowing up to 32 additional 25GbE channels for an aggregate of 80×25GbE in a single rack unit. Two hot-swappable AC power supplies and N+1 fan redundancy are included. The switch is driven by an x86 dual-core CPU running ONIE for management plane operations.
Deployment & Use Cases
Top-of-rack (ToR) leaf for 25GbE compute access with 100GbE uplinks to a spine. Storage fabric for NVMe-over-Fabrics (NVMe-oF/RoCEv2) clusters running Ceph, Lustre, or VAST. Aggregation tier in CLOS-based leaf-spine deployments. AI/ML training pods where 25GbE host adapters connect to GPU servers and the QSFP28 uplinks consolidate into a 100GbE backbone. VXLAN/EVPN overlays for multi-tenant private cloud (workload support depends on the NOS in use).

Compatibility & Hard Constraints
Compatible with NVIDIA Mellanox ConnectX-4/5/6 adapters and standard third-party 25GbE/100GbE SFP28/QSFP28 transceivers and DACs. Airflow direction is fixed at P2C — confirm your hot/cold aisle convention before installation; mixing airflow directions in the same rack causes thermal recirculation. Rail kit is NOT included; standard 19" two-post or four-post rails must be ordered separately. This is an Ethernet-only switch — it does NOT operate in InfiniBand mode. No NOS is pre-installed; the buyer is responsible for installing Cumulus Linux, SONiC, or another ONIE-compatible NOS.
