Building Stacks
stack. Consider these differences when selecting a master node, selecting a backup node, and
configuring failover operation.
Note
We recommend that the master and backup roles be assigned to switches from the same
series. For example, if the master node is an X460-G2 switch, the backup node should also be
an X460-G2 switch. Similarly, if the master node is an X670-G2 series switch, the backup node
should also be an X670-G2 switch.
Note
ExtremeSwitching and X870 series switches can be stacked with themselves and each other
using V400, but they cannot be stacked with other switch models.
Note
The ExtremeSwitching X465 series switches can only be stacked with themselves, and with
ExtremeSwitching and X690 using V160.
Note
The ExtremeSwitching 5520 series switches can only stack with themselves.
When easy setup compares two switches that have the same capability, the lower slot number takes
precedence.
We recommend that you follow the same ranking hierarchy when you plan the physical placement of
the switches in the stack.
