Problem Description

1, a bureau NG-SDH products, OSN3500 and OSN7500 equipment upgrade, version from the original 5.21.13.45 upgraded to 5.21.16.13P04. upgrade tool to use toolkitV1R4, loading method to use the analog package loading.

2. When checking the progress of detailed add-ons, I found an EFS0 single board, the original single board software version is 4.13, and the version being loaded is 2.19.

Alarm message

Processing

1, because the original software version of the single board is 4.13, due to the logic configured as SSN2EFS0, through the simulation package loaded into 2.19, SSN4EFS0 single board although has the function of multi-board ID, but its own single board software can not be used to use the N2EFS0 single board software 2.19;

2、Wait for the end of the analog package loading software, do not activate the single board;

3、Use the board-level loading method, load the single board version to 4.13;

4、Activate the single board after loading;

5、Confirm that the network element works normally and the upgrade is successful.

Root Cause

SSN4EFS0 has the function of multi-board ID, which can be used as SSN1EFS0 or SSN2EFS0 board through configuration, but Toolkit tool reads the list of board information and automatically loads the software package with version matching, and loads the software package with the logically configured board type when loading this board with multi-board ID function.

Solution

Wait for the simulation package to finish loading the software without activating the veneer, then use the board-level loading method to load the veneer version to 4.13 individually, and activate the veneer after loading.

Recommendations and Summary

1, SSN4EFS0 single-board software can not be replaced by SSN2EFS0 single-board software; 2, for SSN4EFS0 single-board, which itself has a multi-board ID function, when configured to use as a N1EFS0 and N2EFS0 single-board, it can not be reported to the LCAS-related alarms, the use of the function of some of the differences, see the opening of the single-board guide.
