Installation Guide

In a stack that has switch models from more than one series, we recommend that the stack master and
backup nodes be from the same switch series. For example, if an X460-G2 switch is the stack master,
the backup node should also be an X460-G2 switch. Refer to the list in Master/Backup Switch
Redundancy on page 239.
Stack configuration, easy setup, and redundancy are fully described in the ExtremeXOS 16.2 User Guide.
ExtremeSwitching switches can be stacked in the combinations listed in Table 147 on page 278. For
each combination, one or more of the following stacking methods are displayed:
