Hi Guys, 

I would like to share with you a guide about how to add two more switch units into a running stack system. 

Let's consider the following stacking system composed by S5700 LI switches connected using service interfaces.

Stack port configuration:

We will add the third unit  SWT3 (S5700LI) having below stack-port configuration and using Xgi2/0/4 we will connect it to xGi1/0/3.


1. Add Xgi1/0/3 to stack-port 1/1

2. Save and power off SWT3

3. Plug in the stack cable. (between XGigabitEthernet2/0/4 and XGigabitEthernet1/0/3)

4. Power on SWT3

SWT1 and SWT2 are still running. 

The new stack system, with 3 switches.

The stack port configuration:

Now we will add the forth unit SWT4. We will configure stack-port as below, using XGigabitEthernet3/0/4 to connect with XGigabitEthernet2/0/3.


1. save and power off SWT4

2. plug the stack cable between Xgi3/0/4 and Xgi2/0/3

3. power on SWT4.

The stack system is still running while adding the new device.

wait for a couple of minutes.... 


Stack port configuration:

Stack topology:

I hope you will find this case interesting. See you!
