Managing OmniSwitch 6400 Series Stacks Roles Within the Stack

A stack of two OmniSwitch 6400 Series switches is
operating normally. The stack consists of a primary
module and a secondary module. (The software on both
elements in the stack is synchronized.)
The primary management module fails or is taken
offline (e.g., powered off or rebooted by the user).
The switch operating as the secondary management module
immediately takes over the primary role. It is at this point
essentially operating as a stand-alone switch.
If the switch that previously failed or was taken offline
comes back online, it will assume the secondary role in the
stack.
