Frequently Asked Questions
What is the difference between MCX755106AS-HEAT and MCX755106AC-HEAT?
The "AS" variant (MCX755106AS-HEAT) has crypto functions disabled but includes secure boot, while the "AC" variant has both crypto enabled and secure boot. Choose AS for environments where encryption offload is not required, or for regulatory compliance reasons.
Is the PCIe Auxiliary Card Kit required?
Only if you plan to use the Socket Direct feature in a dual-socket server. The card can operate as a standard PCIe x16 adapter without the kit, utilizing a single x16 slot.
What operating systems are supported?
In-box drivers are available for Linux (RHEL, Ubuntu), Windows Server, VMware ESXi, and Kubernetes. Refer to the NVIDIA ConnectX-7 user manual for specific versions.
Installation Precautions
- Ensure the server is powered off when installing the adapter
- Use proper ESD protection (ground strap) to avoid electrostatic damage
- Ensure adequate airflow around the card; do not block ventilation holes
- Support cable weight to prevent strain on the ports
- When using Socket Direct, follow the color-coded harness connections to avoid misrouting
