NVIDIA Mellanox MSX1024B-1BFS 1U Open Ethernet Switch, 48x SFP+ 10GbE + 12x QSFP+ 40GbE, Single PSU, Short Depth: This is a 1U short-depth Open Ethernet switch built on the SwitchX-2 ASIC, presenting 48 SFP+ ports at 10GbE and 12 QSFP+ uplink ports at 40GbE. It runs MLNX-OS on an embedded PPC460 management CPU, is configured with one AC power supply, and uses PSU-to-Connector (P2C) airflow. This is a short-depth chassis variant intended for shallow racks, not the standard-depth MSX1024 family. This is a refurbished unit tested by T.E.S IT-SOLUTIONS.
Engineering Context
The MSX1024B-1BFS provides 1.92 Tb/s of non-blocking switching capacity with 48x10GbE plus 12x40GbE, with QSFP+ uplinks supporting 4x10GbE breakout. The short-depth chassis fits shallow telco and edge racks where standard-depth switches will not seat properly. The PPC460 management CPU runs MLNX-OS for L2/L3 management. Single AC PSU; no power redundancy. PSU-to-Connector airflow is appropriate for hot-aisle/cold-aisle layouts where switch ports face the cold aisle. The SwitchX-2 ASIC delivers sub-microsecond cut-through latency.
Deployment & Use Cases
10GbE ToR switch for short-depth telco edge cabinets, MDF/IDF closets, and shallow co-location racks. Leaf node in small leaf-spine fabrics with 40GbE uplinks. Branch-office data hall aggregation. Lab and test-bed 10GbE fabric. Storage fabric for small NAS clusters serving NFS or SMB.

Compatibility & Hard Constraints
Compatible with Mellanox SFP+ DAC and AOC cables, standard SFP+ SR/LR transceivers, MC2207/MC2210 QSFP+ DAC/AOC, and ConnectX-3/3 Pro/4 Lx EN/5 EN adapters. QSFP+ uplinks support 4x10GbE breakout. Single PSU configuration provides no power redundancy. Short-depth chassis is not interchangeable with standard-depth MSX1024 deployments — verify rail kit and cabinet depth. PSU-to-Connector airflow direction is fixed. This is an Ethernet-only switch and does not support InfiniBand.
