Adding a member to a live 3750 switch stack

I have an existing 8 member 3750 stack all running the same IOS and all of the same type.

I wish to add a 9th member to the stack.

The 8 member stack has all 16 stack-wise ports connected.

Can I remove one of those stack-wise cables and connect that cable to this 9th 3750 that I have already provisioned.

Will removing just one stack-wise cable cause the existing 8 member stack to reload?

I know that I have to connect this 9th member to the stack before powering on this standalone but I am concerned that removing one of the stack-wise cables and connecting to this 9th member may cause the entire stack or part of the stack to reload.

Re: Adding a member to a live 3750 switch stack

The switch stack will stay in contact even when you remove one of the stack-wise cable. So you should be able to remove the cable connecting your 8th switch(stackport#1) to your 1st switch(stackport#2), and connect it to your 9th switch(stackport#2). Then connect your 9th switch(stackport#1) to your 1st switch(stackport#2)...then power up your switch and be just fine.
