Downloading a New Software Version

Downloading a New Software VersionFile Synchronization after Downloading

After downloading a new software version to either the primary or secondary flash of the active management module, the software version is immediately copied to the corresponding flash (primary or secondary) of the standby module unless the standby module failed selftest or redundancy was disabled with the no redundancy management-module command.

The configuration files, including which configuration file to use for that flash image, are synchronized. For example, if the active management module is using config1, the standby module will also be synchronized to use config1.

See “Setting the Default Flash for Boot” on page 15-31for information about testing new software versions.

After installing the new software to the active management module, wait a few minutes, and then verify that the standby module has been synchronized with the new software as well (use the show flash command). If the default flash for boot has been set correctly, you can start the standby management module on the new software by executing the boot standby command. This does not interrupt current switch operations yet. After the standby management module has rebooted and is ready for takeover in standby mode
