Dell Mellanox ConnectX-3 CX322A 10Gb Adapter

This dual-port 10Gb SFP+ low-profile adapter installs in Dell PowerEdge servers to add high-speed Ethernet connectivity. It suits administrators upgrading rack-mounted systems that need additional network bandwidth for virtualization or storage traffic.

Dual 10Gb SFP+ ports with low-profile fit

Two SFP+ cages deliver 10Gb per port for fibre or direct-attach copper links. The low-profile bracket fits 1U and 2U chassis where full-height cards cannot be installed. Throughput scales with the number of populated ports and the switch fabric behind them.

Validated for specific Dell PowerEdge models

Compatibility is confirmed for PowerEdge C4140, C6420, FC640, R440, R540, R640, R740, R740XD, R740XD2, R7425, R840, R940XA and XR2. Servers outside this list have not been qualified and may require a different adapter.

Questions about this item

Will the CX322A 10Gb SFP+ card fit in the PCIe slots of my Dell R640 without blocking adjacent cards?

The low-profile CX322A is designed for Dell PowerEdge servers including the R640, and its bracket matches the standard low-profile slot spacing used in those chassis.

How can I confirm both 10Gb ports on the CX322A are linked and passing traffic after installation?

Check the port LEDs on the bracket — solid green indicates a 10Gb link, blinking shows activity — and verify both interfaces report 10 Gbps in the OS network settings or Mellanox firmware tools.

Does the CX322A package include SFP+ transceivers and cables, or must I source them separately?

The listing describes the adapter only; SFP+ modules and direct-attach or fibre cables are not included and must be purchased separately to match your switch and distance requirements.
