A stack of two OmniSwitch 6350 switches is
operating normally. The stack consists of a pri-
mary module and a secondary module. (The
software on both elements in the stack is syn-
chronized.)
The primary management module fails or is
taken offline (e.g., powered off or rebooted by
the user).
The switch operating as the secondary manage-
ment 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 sec-
ondary role in the stack.
