Set up the Physical Stack

After you have installed the individual switches (see "Installing Your Switch"), follow
these steps to create the physical stack.
1. Connect the switches that will form the stack.
See

Connect the Switches to Form the Stack Ring

2. Connect the switches to your management network.
See Connect Your Stack to the Management Network
After setting up and connecting the switches, perform software configuration for the
stack. See "Configuring a New Stack" in the
Connect the Switches to Form the Stack Ring
After you have installed the individual switches, connect them together using the
stacking cables.
The examples in this section show cable connections and the recommended order for
connecting ports to facilitate the easy setup configuration.
In general, it is best to connect Stack Port 2 on one switch to Stack Port 1 on the switch
with the next higher slot number. Although you can connect the switches in any order,
connecting them as shown in these examples will produce better predictability and
easier software configuration.
All connections between stack ports must be directly between switches. A stacking
connection cannot pass through a third device, for example a Virtual Port Extender or
an LRM/MACsec Adapter.
It is essential to create an unbroken data path through all the switches in the stack.
Examples of Valid Stacking Configurations
The examples in the following sections show various physical stacking arrangements:
all switches in a single rack, switches in two adjacent racks, and switches at the tops of
several racks in a row.
