NVIDIA Mellanox MIS5035Q-1BFC 36-Port QDR InfiniBand Managed Switch, 1U, Single PSU: This is a 1U managed InfiniBand switch built on the InfiniScale IV ASIC, presenting 36 non-blocking QSFP ports operating at QDR (40Gb/s) InfiniBand line rate. It is managed by an embedded PPC460EX subnet manager, configured with one AC power supply and PSU-side to connector-side airflow. This is a QDR-generation switch, not FDR/FDR10 or EDR. This is a refurbished unit tested by T.E.S IT-SOLUTIONS.
Engineering Context
The MIS5035Q-1BFC delivers an aggregate non-blocking switching capacity of 2.88 Tb/s across 36 QDR ports, with port-to-port latency in the 100ns range typical for InfiniScale IV silicon. The embedded PPC460EX management CPU runs an OpenSM-compatible subnet manager, removing the need for an external host-based SM in small to mid-size InfiniBand fabrics. The switch supports adaptive routing and congestion control as defined in the InfiniBand QDR specification. Standard 19-inch chassis depth and PSU-to-Connector airflow.
Deployment & Use Cases
QDR InfiniBand fabrics for legacy HPC clusters running MPI workloads. Storage interconnect for Lustre and GPFS file systems on QDR-equipped HCAs. Aggregation switch for ConnectX-2 QDR and ConnectX-3 QDR HCAs. Cost-effective fabric refresh for research labs maintaining QDR endpoints. Lab and test-bed environments validating InfiniBand applications.

Compatibility & Hard Constraints
Compatible with NVIDIA Mellanox QSFP QDR DAC and AOC cables and ConnectX-2 / ConnectX-3 QDR HCAs. The QSFP ports operate at QDR (40Gb/s) and SDR/DDR; they do not negotiate to FDR (56Gb/s) or EDR (100Gb/s). This switch is InfiniBand-only and does not support Ethernet mode. Single PSU provides no power redundancy. Airflow direction is fixed and not field-reversible. PPC460EX management CPU is integrated; no external management module is required.
