ConnectX-6 Dx IC technical selection Q&A
Owner-confirmed and documentation-backed questions with explicit variant applicability and source boundaries.
These questions were prepared for technical evaluation from cited documentation. They are not a measured list of frequently asked customer questions. The applicability line belongs to each answer; do not transfer a statement between order-code, firmware, cooling, length, form-factor or crypto variants.
The products listed below are the applicable catalog references. Answers use owner-confirmed manufacturer-origin product data, scoped public documentation, or explicitly stated engineering guidance. Genuine conflicting values are qualified individually.
Is this a ready-to-install PCIe adapter?
Applicable catalog candidates: MT28924A0-NCCF-VE.
No. MT28924A0-NCCF-VE is an integrated circuit for a qualified board design. An adapter card adds connectors, PCB routing, memory where applicable, power delivery, cooling and firmware configuration.
Public references: MCX631102AN-ADAT card questions - Network Management Products - NVIDIA Developer Forums.
Which network and host-interface parameters are specified?
Applicable catalog candidates: MT28924A0-NCCF-VE.
The owner specification lists 1 network ports, 200GbE and PCIe 3.0/4.0 x16. Use the supported board port mode to determine the final connector arrangement.

Which security variant is this?
Applicable catalog candidates: MT28924A0-NCCF-VE, MT28928A0-NCCF-CE, MT28928A0-NCCF-CEM.
Hardware crypto is disabled in this exact owner-confirmed description. Secure-boot status is not supplied for this bare-IC order code and should not be copied from a finished card.

Is Multi-Host capability established for this suffix?
Applicable catalog candidates: MT28924A0-NCCF-VE, MT28928A0-CCCF-CE, MT28928A0-NCCF-CE.
Multi-Host capability is not stated in the exact owner description for this variant. Do not infer its presence or absence from a related suffix or a finished adapter card.
Public references: MCX631102AN-ADAT card questions - Network Management Products - NVIDIA Developer Forums, H3C network adapters: NIC-ETH641F-LP-2P, Table 24, NVIDIA ConnectX-7 NDR InfiniBand datasheet, NVIDIA ConnectX-7 product brief hosted by PNY (printed DEC21).
Can finished-card power, size or connector specifications be used for this IC?
Applicable catalog candidates: MT28924A0-NCCF-VE, MT28928A0-CCCF-CE, MT28928A0-CCCF-CEM, MT28928A0-NCCF-CE, MT28928A0-NCCF-CEM.
No. Those values depend on the board implementation. Keep chip package dimensions, chip power and thermal limits separate from completed-card dimensions, cage types, brackets and board power.

What engineering details are needed before board design?
Applicable catalog candidates: MT28924A0-NCCF-VE, MT28928A0-CCCF-CE, MT28928A0-CCCF-CEM, MT28928A0-NCCF-CE, MT28928A0-NCCF-CEM.
Obtain the exact package drawing and pinout, power-rail requirements, thermal limits, supported port modes, clocking and firmware/strap requirements. Public adapter-card documentation provides family context, not a complete silicon design specification.
