adding switch into an existing stack

[Duc Vu]

                   Hi all,

    I have an existing stack which comprises of 6 switches, please help with the following questions :

1/ adding another switch into this stack will cause all switches in stack to reboot ? anything that I should be aware of such as different versions ?

2/ maximum switches in one stack should be ?

  Thanks for all help.

Hi.
No. Only new added switch will reboot to complete stack join.
You can pre-provision the new switch on the stack by issuing command
switch nn provision (model).
Also you can renumber the new switch with the position number that it will assume in the stack.

Hi Duc,

If you are stacking 3750 switches you can have a max of 9 switches in one stack. The only thing you have to make sure before adding the new switch is that its IOS version should be exactly same as the IOS version of rest of the stack.

You dont have to worry about any reload of existing stack. Connect the stack cables to the new switch, power it up and it will be added to the existing stack.
