Hello, is it possible to set up the NIC with 2,5 or 5 GBit mixed mode?

The NIC HP FlexFabric 10Gb 2-port 533FLR-T does only offer 1 or 10 GBit speed, no 2,5 or 5 GBit inbetween in Windows 10. TrueNAS only shows a 1 GBit connection as of yet since I do not have another 10 GBit card.

No, this NIC will not link-up at 2.5/5 Gb. The reason is: this NIC is a 10GBASE-T and this standard is older than the newer 2.5GBASE-T and 5GBASE-T standards covering 2.5 GbE and 5 GbE, as a result 10GBASE-T NICs are only backwards compatible to 1000BASE-T and only support 10GbE and 1GbE

You are correct for this device.

But not all 10GBASE-T NICs are unable to do 2.5/5G, some of the newer ones like Intels X550-T2 and X710-T2L do support it.
Interestingly enough while the X710-T2L supports it, the X710-T4 does not, I assume because of the PHY chip Intel is using.

Thank you for the info @AndreiL and @RTM .

So in the end - for home usage - what one is saving in purchasing 2nd hand 533FLR-T nic's one can spend otherwise in terms of switches or Laptop 10 GBit adapters.

Again - home usage - since mentioned HPE nic needs a DIY adapter to run in non-HPE system.

edit:

this downward incompatibility seems to be a non-issue / error in my R&D (newbie to 10Gbit via Ethernet):

I was testing a Asus XG-U2008 10G Switch (2x 10G Ports, 8x GB-LAN Ports, Unmanaged)

The 2x 10G Ports are also not compatible with 2,5G or 5G - therefore my 5G USB dongle was downgrading to 1G at the 10G connetor of the Asus switch.

Alternatives with MultiSpeed Support which should work out with the max speed of each device:

  1. ZyXEL XGS1250 Desktop Gigabit Smart Switch, 11x RJ-45, 1x SFP+ (XGS1250-12-ZZ0101F)
  2. Netgear ProSAFE XS500M Desktop 10G Switch, 4x RJ-45, 1x SFP+ (XS505M-100)
