WeConfig - Firmware Updates
Check out this video to see how WeConfig allows you to batch upgrade firmware of multiple switches. The user can select whether this is performed in parallel or sequentially and is given an option to backup configurations before proceeding.
Note, a firmware upgrade only takes ~5 minutes per switch. That's an incredible time savings over the ~45 minutes+ that we're accustomed to with a very popular industrial switch line.
I also love that there is a single firmware file across all models and that the switch accommodates primary and backup firmware images.
