Replacing a failed stack member

If a Stack Member fails, the effect on the stack depends on which member failed.

  • If the Commander fails, the Standby switch takes over as the Commander and one of the Member switches in the stack is elected as the new Standby. All network ports and stacking ports on the failed switch become non-operational.

  • If the Standby fails, one of the Member switches in the stack is elected as the new Standby. All network ports and stacking ports on the failed switch become non-operational.

  • If a Member fails, all network ports and stacking ports on that switch become non-operational.

If a Stack Member fails:

  1. Physically remove the Stack Member from the stack.

  2. Replace the failed Stack Member.
    NOTE:

    Hewlett Packard Enterprise recommends using the same type (product or "J" number) switch as a replacement since all configuration information is retained.

  • If you are using the same type switch as a replacement:

    1. Provision the new switch using the stacking member N command.

    2. Reconnect all Ethernet ports as they were on the failed switch.

  • If you are using a different type switch as a replacement:

    1. Remove the failed switch from the stack configuration using the stacking member N remove command.

    2. Provision the new switch using the stacking member N command.

    3. Reconnect Ethernet ports and create a new stack configuration on the new switch.

If the replacement switch uses a different version of software, it will be updated automatically to match the software version running on the stack.
