X410 QSFP/SFP+ Interface

All,

 

I read the documentation, and updated my X410 to UHD 4.6 and am running the X4_200 FPGA image. According to that image, I should have 4xSFP 10G lanes for 10G ethernet. I see the Linux network interfaces and they're configured with the default .network files.

 

I'm trying to figure out how to connect this to my Linux PC. I've tried a QSFP-to-SFP adapter with a single 10GTek 10G Transceiver. That didn't work. I tried a few brands of transceivers with different Phy chips.

 

I realized this might NOT be a supported use case but then I see the following in the documentation:


> The NI Ettus USRP X410 is compatible with most brands of SFP+ fiber adapters. In some cases, other equipment in the systems such as 1/10/100 Gigabit Ethernet switches are only compatible with specific brands of SFP+ adapters and cables. As a general rule, we recommend checking compatibility with the switches and network cards in your system before purchasing an adapter.

 

Can the X410 support SFP+ 10G-BaseT transceivers? If so, which ones? Or, do I need to use direct-attach copper?

 

Thanks!
