Hi

Thanks in Advance for supporting

in our network we were using three 3750-48-s switches with stacking one of the switch due to some hardware failure power problem,

now i want to add a new switch 3750-48-s in the existing Stack two switches ,

the old two switches ios version is = 12.2(25r)SEC

the new Catalyst 3750 io verion is =   12.2(35)SE5

can any one help me how to add this switch in the existing two stack switches , with documentation

this is my live network

Regards

Syed,

Hi Syed,

First of all the IOS for all switches should be same. In your case either the old switch needs to be upgrade to 12.2(35)SE5 or degrade the new switch as to the old switch version.

If IOS are not same, then you would see "Version Mismatch"

Below is the link explained how to add a new switch to existing STACK.
