Stacking Methods and Summit Switches
Summit Family Switches Hardware Installation Guide

Combining Switches from Different Series
Note Summit switches can be stacked in the combinations listed in the following table:
*X440-L2 models cannot be stacked.
In a stack that has switch models from more than one Summit series, refer to the list in the previous
section and follow these guidelines:
●
The stack master and backup nodes should be from the same switch series. For example, if a
Summit X480 series switch is the stack master, the backup node should also be a Summit X480 series
switch.
●
Follow these guidelines for the specific listed switch combinations:
-
If Summit X480 series and X650 series switches are both present in the stack, the master and
backup nodes should both be Summit X480 series switches.
-
If Summit X480 switches and X670 series switches are both present in the stack, the master and
backup nodes should both be Summit X670 series switches.
●
Although you can combine Summit X460, X480, and X670 series switches in a stack, you should be
aware that the routing table limit for the Summit X460 series is lower than the limits for the other
two switch series. For more information, refer to the
ExtremeXOS Configuration Guide
.
In a stack with multiple master-capable switches, it is possible for more than one switch to try become
the stack master if the stack is physically severed. Such a dual-master condition would cause confusion
