Single-Port Adapter for Enterprise Networking

The Dell MCX383A-FCNA is a single-port network adapter card built for high-performance enterprise environments. It uses a Mellanox ConnectX-3 Pro EN controller to deliver ultra-low latency and powerful throughput. The PCIe Gen3 x16 interface ensures full bandwidth potential for data centres, HPC clusters, and demanding virtualization workloads. Its compact low-profile PCB design fits space-constrained builds.

Installation Notes and Common Issues

The card installs into a PCI-Express x16 slot and requires no bracket, which is not included in the package. The low-profile PCB measures 6.6" in length, 2.7" in width, and 0.8" in height, weighing .3 lbs. Installers must supply a compatible bracket for their chassis to secure the card properly. Verify that the system provides a physical x16 slot and that the operating system includes driver support for the ConnectX-3 Pro controller.

Pre-Order Compatibility Checks

Confirm the target system has an available PCIe Gen3 x16 slot and sufficient physical clearance for the card dimensions. Ensure the chassis can accommodate a low-profile card and that you have an appropriate bracket for mounting. Check that your network infrastructure supports the adapter's single-port configuration and intended throughput requirements. Buyers needing multi-port connectivity or an included mounting bracket should consider other options.

Questions about this item

How do I confirm the MCX383A-FCNA is operating at full PCIe Gen3 x16 bandwidth after installation?

Verify link speed and width in the OS device manager or Mellanox firmware tools; they should report PCIe Gen3 x16 with no errors.

What ships with the MCX383A-FCNA and which mounting hardware must be sourced separately?

The adapter card ships alone; a low-profile or full-height bracket is not included and must be purchased separately for your chassis.

Which Dell part number identifies the MCX383A-FCNA variant with the ConnectX-3 Pro EN controller?

Part number XK4C4 (also listed as 0XK4C4 or IL-0XK4C4) identifies this single-port ConnectX-3 Pro EN adapter.
