2.6.183 SW-VER
Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)
Logical Object: EQPT
The Software Version condition is reported when a new software version is activated on the
ONS 15600 SDH. When a new version of software is uploaded, it results in the active TSC card running
the new version and the standby TSC card running the old version. This situation raises the SW-VER
condition. It remains until the user accepts the new version in the CTC. The acceptance causes the
standby TSC card to reboot and upload the new version.
If the user does not accept the version, the active TSC card switches to the standby TSC card with the
original version. After the switch, the new standby TSC card reverts to the previous version.
