NVIDIA Mellanox MSN2410-BB2FO Spectrum-Based 25GbE/100GbE 1U Open Ethernet Switch: This is a 1U top-of-rack Open Ethernet switch built on the NVIDIA Mellanox Spectrum ASIC. The chassis provides 48 SFP28 ports (1/10/25GbE) and 8 QSFP28 ports (40/100GbE, with breakout to 4x25GbE on supported ports). This SKU is the P2C (front-to-back from PSU side) airflow variant and ships with ONIE bootloader (no preinstalled NOS). This is a switch system, not a line card or NIC. This is a refurbished unit.
Engineering Context
The Spectrum ASIC delivers 3.2 Tb/s switching capacity with 2.38 Bpps forwarding rate and ~300ns port-to-port latency. The platform supports VXLAN routing and bridging in hardware, EVPN, ECMP, dynamic load-balancing, and What Just Happened (WJH) telemetry for granular packet-drop visibility. The 8 QSFP28 uplinks can be configured as 100GbE, 40GbE, or 4x25GbE breakout (FEC and breakout cable required). Hot-swappable dual AC PSUs and N+1 hot-swap fans support continuous operation.
Deployment & Use Cases
25GbE Top-of-Rack switching for compute racks paired with ConnectX-4/5/6 Lx NICs. Leaf in a 25/100GbE spine-leaf fabric with QSFP28 uplinks. Front-end Ethernet fabric for NVMe-oF and software-defined storage clusters. Cumulus Linux fabrics built with NetQ and Ansible automation. Container and Kubernetes networking with EVPN-VXLAN overlays. Racks where ports face the hot aisle and psus face the cold aisle.
Technical Specifications

Part Number: MSN2410-BB2FO
Switch Family: SN2410 (Spectrum)
Form Factor: 1U rack-mount
Ports: 48x SFP28 (1/10/25GbE) + 8x QSFP28 (40/100GbE)
Switching Capacity: 3.2 Tb/s
Forwarding Rate: 2.38 Bpps
Port-to-Port Latency: ~300ns
Airflow: P2C (Power-to-Connector) — air enters at the PSU side and exhausts at the port side
Power: Dual hot-swap AC PSUs (1+1 redundancy)
Cooling: N+1 hot-swap fans

Compatibility & Hard Constraints
Compatible NICs: NVIDIA Mellanox ConnectX-4 Lx, ConnectX-5, and ConnectX-6 Lx EN adapters at 10/25/100GbE. Compatible cabling: MCP1600 / MCP2M00 family DAC, MFA1A00 family AOC, MMA1B00 SR4 / MMA1L10 LR4 / MC2210 family transceivers (verify the exact transceiver against the QSA / SFP / QSFP support matrix for this model). Network OS support includes NVIDIA Cumulus Linux, NVIDIA Onyx (formerly MLNX-OS), SONiC, and other ONIE-compatible distributions. Ships with ONIE (Open Network Install Environment) bootloader only — no preinstalled NOS. The operator installs the network OS at deployment (Cumulus Linux, NVIDIA Onyx, SONiC, or other ONIE-compatible distribution). The P2C (front-to-back from PSU side) airflow is designed for racks where ports face the hot aisle and PSUs face the cold aisle; do not mix airflow directions in the same hot/cold aisle row. This is an Ethernet-only switch; it does not run InfiniBand. PSU and fan modules are FRUs and orderable separately.
