NetFPGA-SUME Virtex-7 FPGA Development Board:Test 10G loopback was Failed

[Carl-arch-tech]

Hello ,
I bought the 410-301(NetFPGA-SUME Virtex-7 FPGA Development Board),and mate with Optical module of ES-T5-R.When I use the official test program（https://github.com/NetFPGA/NetFPGA-SUME-public/wiki/Acceptance-Test-Project）.It was failed of test 10G loopback.May I ask which part may be the problem?And how to solve it.Can anyone solve my doubts, please！
Are there other test procedures that can be tested?If so, can you give me a copy.My e-mail:jingxuan.zhang@rightic.cn.Thanks!
Here is the datasheet of ES-T5-R.
Looking Forward for your reply.

Did you configure the ports with a 10g loopback connector as in this photo? All four ports are tested simultaneously so four optical modules each with a loopback fiber will be required.

As our pictures show：the board configured four 10G optical modules.
The driver of sume-riffa has been loaded, and we can see four network ports nf0~nf3 via lsconfig command.

The problem is we failed when we test the 10G loopback with the Github's Acceptance Test Project.

So do you have any suggestions on that?

Thanks!

You have the correct configuration for the reference switch but not the reference Nic (or acceptance tests) In each of those cases, the loopback is connecting tx to Rx on the same port Using a simply fiber loop as in our picture or a device such as https://www.fs.com/products/50010.html

Thanks for your suggestions. It really helps a lot.

Actually, the problem caused beacause we used 10G SFP+ copper transceivers instead of optical modules.
We found loopback test in the Acceptance Test Project is just for optical modules.

Do you have the 10G loopback test program for 10G SFP+ copper transceivers?

Thanks and kind regards,

We connected NetFPGA-SUME to computers by 10G SFP+ copper transceivers, but it couldn't communicate.

What the configuration we need if connect 10G SFP+ copper transceivers to NetFPGA-SUME?

Can you give me some suggestions?
