Problems with CRU configuration

Dear Experts,
I got issues during CRU configuration.
Log:

[flp@aliflp-fit COMMON]$ ./standalone-startup.py -i 2:0.0 -c local -o 1 -p -l 5 -m packet -x ttc

LTU seems to work well.

P.S. this problem occurred after a power cut in evening 18/10/2019. Could it be a problem due to sfp device?

Best Regards,

Ciao Artur,
as discussed we should meet this week and have a look at your setup.
Your system is quite old and we should update the firmware and the software.
I will contact you to schedulke a meeting.
Cheers

Dear Artur,
From the report I see that the ONU RX is not locked (that’s why PON Tx also fails), are you sure that the LTU/PON link is ok and has the right clock frequency? Can you share the output of ./report.py as well?
Did you try to restart the LTU (running “olt init”)?

Best regards,
Tuan

Ciao Artur,
indeed I logged in cand configure your CRU to use the LTU.
As Tuan pointed out it looks like the clock coming from the LTU is not right.

Here the output of the report.py

 ./report.py -i2:0.0

Dear All,

thanks a lot! Rebooting of LTU helped.
