test fiber-link no.777 FAIL

Hi, all.

I'm looking for guidance on how to resolve the FIBER-LK Test No.777 Result: FAIL.

This is how I have the fiber links:

When I test fiber-link no.1, this is what I get:

I cannot get rid of that FAIL on test no.777.

If I do a test board on slot 01c02, everything looks good:

If I do a test board on slot 01e02, I still get the test no.777 FAIL.

So, my question is what could be the problem that is generating the test no.777 to fail?

I already change the TN570 on slot 01c02 like 2 or 3 times and I'm still getting that FAIL message.

Can anybody help me with this? Thank you in advance.
 
Per the maintenance manual you now need to look at display errors for SNI-BD, SNI-PEER, or FIBER-LK.
Also, there were many issues with the TN570 so you should probably be on a TN570Dv6 and your SNI should be a TN573Bv7.
You didn't indicate your release of software. I'm also assuming based on the SNI/EI boards in your screenshot this is a MCC cabinet configured as 5-port networks so do you have the correct expansion carrier in 01C. I believe the carrier should be an AF. And of course with the modified harness, is the J connector attached on the carrier.
 
Hello, jimbojimbo.

Thanks for answering.

I include a file with several images of the configurations I have for the PPN and EPN. Could you please take a look?

I used the display error for the TN573 in slot 01e02 and this is what I get:

I did some reading about the SNI-PEER error types: 3585, 257, 512 and 769, but to clear those values I'd have to use the "test board 01e02".

But I still get the failure audit #777.
