产品描述
MCX631102AN-ADAT is a ConnectX-6 Lx Ethernet adapter with two SFP28 ports, support for 1/10/25 GbE and a PCIe 4 x8 host interface. This low-profile HHHL configuration uses the tall-bracket reference assembly. Hardware crypto is disabled; secure boot is disabled. The AN and AS variants share network and host-interface specifications but differ in secure-boot configuration, so the full suffix matters in a replacement or qualification plan.

产品问答

What is the material difference between AN and AS?

AN has secure boot disabled; AS has secure boot enabled. Both listed variants have crypto disabled, dual SFP28 ports and PCIe 4 x8. Treat secure boot as a separate selection field from crypto.

Does this 25 GbE card provide a 50 GbE single port?

The exact MCX631102 variants are specified for two SFP28 ports at 1/10/25 GbE. A separate MCX631105 QSFP28 product supports the single-port 50 GbE configuration; family capability does not change this SKU.

What power budget does the passive-cable specification use?

At PCIe Gen 4 the shared exact-model specification lists 11.53 W typical and 12.94 W maximum using passive cables. Active modules add power and may change airflow requirements.

Is a passive heatsink sufficient without server airflow?

No such guarantee is given. The published 55°C airflow requirement is 300 LFM from heatsink to port with passive cables; active modules require more airflow in the listed conditions.

Does an older PCIe slot change the card identity?

The card supports PCIe Gen 3/4 x8 and lower-generation compatibility as documented. Check the actual negotiated width and speed; a physical slot does not guarantee the preferred host bandwidth.

Can firmware be chosen solely from the marketing model?

Record the exact label, hardware revision and PSID before firmware work, especially for OEM-labelled cards. A family driver or a shared chip marking does not establish that an arbitrary firmware image is appropriate.
