Before you order

  • Confirm the exact SKU, part number, specification option and quantity.
  • Confirm the host platform, port, electrical interface and firmware requirements.
  • Confirm availability, lead time, destination and applicable service terms before payment.
Description
MCX755106AS-HEAT is a half-height, half-length ConnectX-7 adapter with two QSFP112 network ports for 200 GbE or NDR200 InfiniBand. Ethernet is the default mode. The primary host connection is PCIe 5.0 x16, with an additional x16 Gen 4 connection available through a separately selected Socket Direct auxiliary assembly. This AS variant enables secure boot and disables hardware crypto. Select the exact primary card, server topology and extension kit together.

Product questions & answers

Is this the single-OSFP MCX75310AAS-HEAT?

No. MCX755106AS-HEAT has two QSFP112 ports and Socket Direct readiness. MCX75310AAS-HEAT is the single-OSFP configuration.

Which protocol is the default?

The exact specification lists Ethernet as the default and supports 200 GbE and NDR200 InfiniBand. Confirm the configured port mode before selecting the switch and interconnect.

Is the auxiliary card included?

No. NVIDIA explicitly excludes the passive auxiliary connection card and two harnesses from the Socket-Direct-ready primary-card kit. Select those components separately.

Does the optional path have the same interface as the primary slot?

The primary slot is PCIe 5 x16. The optional connection is described as an additional Gen 4 x16 path. The printed optional signal rate is inconsistent and remains a field-level qualification item.

Does secure boot mean this variant enables crypto?

No. The AS suffix is explicitly secure-boot-enabled and crypto-disabled; the AC variant has a different crypto configuration.

How should its power figure be used?

The published typical power is 24.9 W with passive cables in PCIe Gen 5 x16. It is not a maximum-system-power figure and does not establish the budget for an arbitrary active optic or auxiliary assembly.
