Installation Guide

Setting up the Physical Stack
After you have installed the individual switches (see #unique_337), follow these steps to create the
physical stack.
1. Connect the switches that will form the stack.
See Connecting the Switches to Form the Stack Ring on page 287.
2. Connect stacking cables to the switches.
See Connecting Stacking Cables on page 300.
3. Connect the switches to your management network.
See Connecting Your Stack to the Management Network on page 312.
After setting up and connecting the switches, perform software configuration for the stack. See
"Configuring a New Stack" in the ExtremeXOS 16.2 User Guide.
Connecting 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.
Note
The connection recommendations in this section do not apply to Summit X650 series
switches with installed VIM1-SummitStack512 modules. For information about connecting the
ports on the VIM1-SummitStack512 modules, see Using the VIM1-SummitStack512 Module on
page 294.
For instructions to connect specific types of stacking cables, see Connecting Stacking Cables on page
300.
Combining Dierent Types of Stacking Ports
Figure 214 shows a sample configuration using the following switches:
• Summit X650 series switches with installed VIM1-SummitStack256 modules
• Summit X450a series switch with integrated SummitStack ports
• Summit X480 series switch with installed VIM2-SummitStack module
