NVIDIA Mellanox MSN2410-CB2F 1U Open Ethernet Switch: This is a 1U short-depth Spectrum-based Ethernet switch with 48 × SFP28 ports for 25GbE access and 8 × QSFP28 ports for 100GbE uplinks (NVIDIA P/N 920-9N112-00F7-0X2). The CB2F suffix denotes the dual AC PSU configuration with P2C (Power-to-Connector, forward) airflow. This is a fully managed open-networking switch. This is a refurbished unit.
Engineering Context
The MSN2410-CB2F is built on the Mellanox Spectrum ASIC. Combined non-blocking bandwidth across 48 × 25GbE access ports and 8 × 100GbE uplinks reaches 2.0Tb/s. Each QSFP28 uplink can be configured as 4 × 25GbE breakout for additional access capacity. The short-depth chassis fits telco-style cabinets where standard depth racks are not available. ONIE-bootable for Mellanox Onyx, Cumulus Linux, or SONiC. P2C airflow uses standard data center cold-aisle/hot-aisle orientation.
Deployment & Use Cases
Top-of-Rack 25GbE access for ConnectX-4 Lx / ConnectX-5 server adapters with 100GbE leaf-spine uplinks. Edge data centers and telco micro-DCs where short-depth racks are required. AI/ML cluster connectivity for inference nodes using 25G NICs. NVMe-oF storage tier with 100G uplink to spine.
