A stack of two OmniSwitch 6250 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.
