I will second this. 10GiGe cards for PCs are not expensive these days,
neither are the SFP+ optical transceivers. Short
optical patch-cords for these are also very very reasonably priced.

Hi, I cannot get the NI-2943R (=Ettus x310) connected to the PC
via the PCIe transport connection. The Ettus firmware is upgraded
to the currently latest one, UHD version is
UHD_4.7.0.0-0ubuntu1~jammy1. The default HG image was uploaded to
Ettus. The upload was done via SFP+ Port 0 Interface, 1GbE copper
SFP connected. Since I had Terasic PCIe x4 Cable Adapter (PCA)
conversion card available, I would like to use that instead of
1GbE SFP port.
PC is Precision 3680 Tower WS. The OS is Ubuntu 22.04.5 LTS with
kernel Linux 6.8.0-49-generic. The NI Linux device drivers were
installed according to the guide:
https://files.ettus.com/manual/page_ni_rio_kernel.html
Command lspci -k -d 1093:c4c4 returns nothing. I checked the
Terasic PCIe x4 PCA LEDs during operation: If I first power on the
NI-2943R before powering up the PC as recommended, the LEDs on PCA
stay off. In the other order, powering up NI-2943R after the PC,
the D2 edge, D3 power and DN2-DN4 (signal detect output for CH_B,
receiver detect outputfor CH_A0 and CH_B0).
I have tried various grub options, disabling power saving modes
there and so on but now just more or less helpless. Does anyone
has had similar issues with the similar HW.
I attached output list of dmidecode, lspci and lshw commands.
