This case occurs when the T2000 queries the board software on a new OptiX OSN 3500 NE. On the T2000, the AUX board software version in the main subrack is displayed as 3.13, whereas the AUX board software version in the extended subrack is displayed as 1.0.
The customer wonders why the AUX boards in the same batch are of different versions.
The OptiX OSN 3500 NE version is V100R006 C02B012.
This fault is due to a defect in OptiX OSN 3500 V100R006 C02B012. Upgrade the OptiX OSN 3500 to V100R006C02B014.
The AUX works on a hardware basis and does not run software. The AUX version information displayed on the T2000 is sourced from the file information stored on the SCC. On OptiX OSN 3500 V100R006 C02B012, the file updates the AUX version in the main subrack to 3.13, but does not update the AUX version in the extended subrack. Thus, the AUX version in the extended subrack is displayed different from the AUX version in the main subrack.
As a display error, this fault does not affect the services. Explain the error to the customer.
