Specifications | NVIDIA ConnectX-8 SuperNIC for OCP Spec 3.0 User Manual

The ConnectX-8 SuperNIC is designed and validated for operation in data-center servers and other large environments that guarantee proper power supply and airflow conditions.

The SuperNIC is not intended for installation on a desktop or a workstation. Moreover, installing the adapter card in any system without proper power and airflow levels can impact the SuperNIC's functionality and potentially damage it. Failure to meet the environmental requirements listed in this user manual may void the warranty.

Please install the ConnectX-8 SuperNIC in a PCIe slot capable of supplying the required power and airflow.
