Can't detect CX6DX NIC

Infrastructure & Networking Adapters and Cables Ethernet Adapter Cards

Hello,

I am having trouble configuring CX6DX (MPN: MCX623106AN-CDAT, Serial Number: MT2211T18421) NIC on my PC.

I typed lspci command and it shows below. As I know, NIC should be detected as Ethernet controller NOT Memory controller

tkhan@tkhan-XPS-8940:~$ lspci | grep Mell
01:00.0 Memory controller: Mellanox Technologies MT2892 Family [ConnectX-6 Dx Flash Recovery]

After doing mst start, mst status shows:

tkhan@tkhan-XPS-8940:~$ sudo mst status
MST modules:

MST PCI module is not loaded
MST PCI configuration module is not loaded

PCI Devices:

01:00.0

Also mlxfwmanager failed to open device even though I checked that there is /dev/mst/mt530_pciconf0.

I also tried several flint commands to burn the firmware on NIC device, and it always gives “MFE_ICMD_NOT_SUPPORTED” error.

sudo dmesg shows below and I wonder if that can be a clue about what’s causing the trouble.

tkhan@tkhan-XPS-8940:~$ sudo dmesg | grep mlx
[ 0.960286] mlx_compat: loading out-of-tree module taints kernel.
[ 0.960302] mlx_compat: module verification failed: signature and/or required key missing - tainting kernel

I tried rebooting and power cycling several times but it doesn’t solve the issue, and I have no idea what is causing this error. Could anybody help me?

Hello dwhwang313,

Thank you for posting your inquiry on the NVIDIA Developer Forum - Infrastructure and Networking - Section.

The issue is that the adapter you have is in flash recovery mode, which means the flash is corrupted or damaged.

Recommendation is to RMA this adapter if you still have valid warranty or entitlement.

Thank you and regards,
~NVIDIA Networking Technical Support
