When upgrading uc560, should some phones be disconnected?

[lbroering]

We are looking at upgrading a UC560 that has 40 plus 7965 phones connected from Software Pack 8.1 to Software Pack 8.2. I think the phones will try to upgrade their firmware when the system reboots. Does anyone have any experience that they would share? Will I need to disconnect some of the phones so they do not all try to pull the firmware at one time or does the system take care of this OK? Thanks in advance.

I just did an upgrade on a UC560 with a mix of around 56 phones (7900, SPA500) and I didn't have any issues with phones pulling the firmware all at once.
