Hello. I want to upgrade the IOS on my 4507R (currently running 12.1(19)EW1), and the documentation says that since I have redundant Sup's, I don't need to reload the switch. The problem is that it says that the modules will reload, which, assuming it means all of the modules in the switch, will essentially bring the network down anyway.
Am I reading the docs right? This is our core switch, and I would really like it if everything connected to it didn't have to drop while the modules (WS-X4548-GB-RJ45, WS-X4306-GB) rebooted.
Any advice?
