For example, in a stack that combines X460-G2 or X670-G2 switches with other switch models, an
X460-G2 or X670-G2 switch might provide more memory and more features than other switches in the
stack. Consider these differences when selecting a primary node, selecting a backup node, and
configuring failover operation.
Note
Assign the primary and backup roles to switches from the same series. For example, if the
primary node is an X460-G2 switch, the backup node should also be an X460-G2 switch.
Similarly, if the primary node is an X670-G2 series switch, the backup node should also be an
X670-G2 switch.
Note
The ExtremeSwitching 5420 series switches can only be stacked with themselves, or with
ExtremeSwitching 5520 using Alternate stacking.
When easy setup compares two switches that have the same capability, the lower slot number takes
precedence.
Follow the same ranking hierarchy when you plan the physical placement of the switches in the stack.
