How to handle the issue if the upgrade progress of an OLT is consistently 99%?

Hello,

During the upgrade, run the display progress load command to query the package file loading progress. The progress stays at 99% for a period of time. Please wait patiently.

Thanks

Dear Jul_ang!

Please use the method provided by wissal to observe.

If there's no change in two hours，

Check whether the hardware matches the software.

Check whether the software package of the new version is complete.

If the problem still cannot be solved, please contact the TAC engineer to apply for the establishment of a ticket, and the engineer will handle it for you in real-time
