Note: When switches are connected in a stack configuration and all high-speed stacking
cables are connected before powering up the switches, one switch in the stack will be
automatically designated as the Manager of the stack and its Console port will remain
active. All other switches will become Member switches and their Console ports will be
deactivated.
