I have an existing 3750 on our network which is full and a new 3750 has been bought with the intention of stacking it onto the full one. We have never done this before and are a bit unsure of the steps. I have read the stacking section of the 3750 config guide and a lot of the posts on here but I'm still confused.
Existing Switch = Stack 1, New Switch = Stack 2
Stack1 1 has an IP address, tacacs setup, password, 2 vlans in use and is running IOS ver 12.2(25)SEB4
Stack 2 is brand new out of the box with no config changes and is running IOS ver 12.2(35)SE5
From what I read both IOS versions have to be identical. Does this mean Switch 1's IOS has to be upgraded?
DO I need to setup a local password, rename Switch 2 etc, or will the switch only be accessible via the stack IP address. My fear is that someone could just plug a console cable on and have no password etc.
If someone could just give me the steps I need to complete to get this going I would be most grateful.
