The NVIDIA ConnectX-6 Lx EN adapter card (MCX631432AS-ADAB) is a dual-port SFP28 Ethernet network adapter in the Small Form Factor (SFF) OCP 3.0 form factor. It supports Ethernet data rates of 1/10/25 Gb/s and connects to the host over PCI Express Gen 4.0 with 8 lanes at 16.0GT/s, with compatibility for PCIe 2.0 and 1.1. This model includes host management and Secure Boot, without crypto, and uses a thumbscrew (pull tab) bracket for retention.
The SFP28 connectors accept copper and optical connections, with up to 1.5W available per port. The card measures 115.00mm x 76.00mm and operates on 3.3VAUX and 12V. Typical power with passive cables in active mode is 11.8W, with a maximum of 13.4W active and 9.2W standby on passive cables, or 16.7W active and 10.9W standby with 1.5W active cables.
It is suited to OCP 3.0-equipped servers in data centre and enterprise networking environments.
