Ethernet ports show as "cable unplugged"

I am setting up a new peer to peer Network
Windows Server 2022 + Windows 11

2 cards MCX354A-FCBT
Cable Dell 05NP8R SAS Kabel 40Gb QSFP+ / QSFP+ 1m

Driver Version : 5.50.14740.0
Firmware Version : 2.42.5000
Port Number : 1
Bus Type : PCI-E 8.0 Gbps x8
Link Speed : ----
Part Number : MCX354A-FCBT
Network Status : Disconnected
Adapter Friendly Name : Ethernet 4

Cabling the card do the same card in another Windows box and setting both to Ethernet mode brings up the connection immediately.
