I have a new UC520 that I am loading for a customer site. Goal is to have 7.0.4 loaded on it. I am running CCA 2.2(2).
The system consists of a UC520-24U, ESW-540-24 and SPA525G phones.
Out of the box, I could not upgrade to 7.0.4 but I was able to upgrade to 7.0.2. I figured I had to do the upgrade in two steps.
When I go to upgrade to 7.0.4 - I go to Software Upgrade, Upgrade Settings and then choose browse. I browse to the uc520-7.0.4 zip file. When I select this I get the following error message:
Software pack is not valid for this device. Please provide correct software pack
I have tried multiple copies of the 7.0.4 image to make sure it wasn't corrupt and I tested the same file on another demo system we have running and it worked fine.
Please suggest a course of action.
I have considered moving to 8.0.2 but I really don't want to put 8.0.2 in production for a client until we have had a chance to run it on our internal systems and our demo unit. The last time I tried installed 8 on my demo unit it blew up so I went back for now.
