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 X590 is not supported with ExtremeXOS version 30.1.
  4. 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 Master/Backup Switch Redundancy.

Stack configuration, easy setup, and redundancy are fully described in the ExtremeXOS 16.2 User Guide .

Notes:
  1. X440-L2 models cannot be stacked.
  2. X460-G2 SummitStack-V is available only on 10G models.
  3. X450-G2 SummitStack-V is available only on 10G models. SummitStack-V84 is available only in stacks of Summit X450-G2 switches running the same version of ExtremeXOS.
  4. 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 Summit series, refer to the list in Master/Backup Switch Redundancy 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 switches are both present in the stack, the master and backup nodes should both be X480 switches.
    • If Summit X480 switches and X670 switches are both present in the stack, the master and backup nodes should both be X670 switches.
  • Although you can combine Summit X460, X480, and X670 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 16.2 User Guide .
