  • Confirm availability, lead time, destination and applicable service terms before payment.
Description
MCX75310AAC-NEAT is a HHHL ConnectX-7 PCIe adapter with 1 OSFP port and a PCIe 5.0 x16 host interface. The card supports 400GbE and NDR InfiniBand, with InfiniBand as the default link type. Secure boot is enabled and hardware crypto is enabled. Select the matching connector, cooling arrangement and validated software release for the target server.

Product questions & answers

How should a link that will not come up be checked?

Check seating, cable connection, the intended port configuration and supported firmware/driver combination. Compare cable or module compatibility and the peer switch settings before treating a missing link as hardware failure.

Which connector and host slot does this order code require?

MCX75310AAC-NEAT uses 1 OSFP port and PCIe 5.0 x16. The card is HHHL and ships with a tall bracket. Match the cage, optics or cable, lane width and chassis clearance.

Does it support Ethernet as well as InfiniBand?

The exact ordering table lists 400GbE and NDR InfiniBand.

Are crypto and secure boot the same option?

No. Secure boot is enabled on this order code; crypto is enabled. These are separately identified capabilities, so retain the exact suffix when ordering.

Can the quoted typical power be used as the server thermal limit?

No. NVIDIA lists 25.9 W with passive cables in PCIe Gen5 x16 for this variant. Maximum power and required airflow need the full product specifications and the exact server/optics configuration.

What special selection check applies to this variant?

Match the exact crypto suffix and mechanical drawing. A shared ConnectX-7 name does not make a different connector, bracket or form factor a substitute.
