Note
1 For X440-G2 and X460-G2, SummitStack-V is available only on 10G models.
2 For X450-G2, SummitStack-V is available only on 10G models. SummitStack-V84 is
available only in stacks that consist entirely of X450-G2 switches.
3 The X670-G2-72x can stack only with SummitStack V using front panel 10G ports.
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
Stack configuration, easy setup, and redundancy are fully described in the
Building Stacks
