Where do I find the product number mapping between HPE OEM to Mellanox.

I’ve got several HPE DL385 Gen10 with HPE 10/25 GB 2-port 640FLR-SFP28 and need the Firmware 14.26.4012 which is already released by Mellanox but not yet by HPE.

I’d like to download the firmware from here: https://www.mellanox.com/support/firmware/connectx4lxen but don’t know which OPN.

NIC Info:

Device Type: ConnectX4LX

Part Number: 817749-B21_Ax

Description: HPE Ethernet 10/25Gb 2-port 640FLR-SFP28 Adapter

PSID: HP_2690110034

HPE wants me to ask Mellanox - please don’t tell me to ask HPE.

Thank you very much in advance,


Hi Markus,

The firmware image should be provided by HPE, since these cards are OEM HPE branded cards.

According to HPE website, the latest firmware version available for your card is 14.26.1040.


I suggest to communicate with HPE and ask them for the latest version (equivalent Mellanox OPN is MCX4121A-ACAT).
