产品描述
MCX753436MS-HEAB is an OCP 3.0 SFF ConnectX-7 adapter with two QSFP112 ports, PCIe 5.0 x16 connectivity and thumbscrew/pull-tab retention. It supports 200 GbE and NDR200/HDR InfiniBand, with Ethernet as the documented default. Multi-Host and Socket Direct are listed capabilities subject to the server implementation. Hardware crypto is disabled and secure boot is enabled. Its HEAB mechanical and port configuration should be kept distinct from the HEBB port-split variant.

产品问答

Can this replace a stand-up HHHL card?

It uses an OCP3 SFF connector and thumbscrew/pull-tab retention. It requires the corresponding OCP server interface rather than an ordinary stand-up PCIe installation.

How does HEAB differ from HEBB?

The opened ordering table identifies HEBB as a port-split-capable variant; HEAB is a separate dual-QSFP112 OCP configuration. Do not transfer HEBB port-splitting claims to HEAB.

Which security variant is MS?

MCX753436MS-HEAB enables secure boot and disables hardware crypto. MCX753436MC-HEAB is the crypto-enabled counterpart.

Will Multi-Host work in any OCP slot?

No automatic compatibility is established. Baseboard lane routing, server firmware and supported adapter configuration determine whether the advertised Multi-Host/Socket Direct capabilities can be used.

Which typical-power condition is documented?

24.5 W with passive cables and PCIe Gen 5 x16. The document’s connector power ceiling is marked not thermally supported; it must not be used as an optics thermal qualification.

Which network mode should be checked at installation?

The ordering row specifies Ethernet by default, with 200 GbE and NDR200/HDR InfiniBand support. Record the actual firmware, PSID and configured protocol before link testing.
