I have 5 Cisco switches 4 of them are 3750 Series and 5th switch is 3750 G series, 1st 4 switches are part of stack and 5th is not.
Design for 4 stack switches is :
Switch 1 Connect to Switch 4
Switch 1 also connects to switch 2 with a 2nd cable
Switch2 connects to switch 3
Switch3 connects to switch4
Can I remove the cable from second port from the switch4 which is connected to switch1 and plug switch 5 to switch4 and remove cable plug to 2nd port of the switch5.
If do the above is there any specific configuration which I need to do?
What is the down time I am looking at.?
it will not work or rather it is not built to work that way.
You can have different 3750 hardware, but it is designed to have one and only one IOS.
so if the switches ios is an old one start with upgrading all the switches to the same IOS then (that will cause a reload) Then you can add the single switch to the stack.
Adding the switch should not cause any downtime however that said I would do it out of office hours since I have seen it crash even though it should not when adding switches to a stack.
and of course make a backup of the config in the switches first otherwise you might get a not so nice surprise, hopefully the master will still be of the stack, but then you will need to reconfig the switch you are adding.
dont forget to set prioroty to the masterswitch that are master in the stack today.
