Would anyone by chance have a firmware upgrade template for a CBS 350? I took a look in the shared templates and didn't come across it.
Unfortunately you don't see those CBS switches in most Orion customer environments, so it's quite possible you will have to create your own template. On the plus side looking at the docs it is a really simple upgrade process so you can probably just take one of the existing templates and remove steps until it just does the few steps the CBS switch needs.
