Device: ConnectX-7 200GbE / NDR200
P/N : MCX755106AC-HEAT
When connected NIC card to Host , I am able to see ethernet entries as below,
enp1s0f0np0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
ether 58:a2:e1:db:fb:28 txqueuelen 1000 (Ethernet)

but when I am using ethtool with any of two ethernet port, I see it says, “Link detected: no (No cable)”

I am using below cable for connection,
QSFP DD Cable
I am looping back connectX-7’s both ports with this cable.
Please help me with the correct cable to be used with connectX-7.
Also what output should I expect when I connect correct cable to connectX-7 NIC card ?
Thanks for helping in advance.
