Note.
For management module redundancy to work effectively, the software on all switches operating in
the stack must be synchronized at all times. Refer to
“Synchronizing Switches in a Stack” on page 7-36

A stack of four OmniSwitch 6350 switches is
operating normally. The stack consists of a pri-
mary module, secondary module, and two ele-
ments operating in idle status. (The software
on all elements in the stack is synchronized.)
The primary management module in the stack
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. Meanwhile, the adjacent switch—previously
operating in idle status—now assumes the second-
ary management role.
If the switch that failed or was taken offline comes
back online, it will assume an idle role in the
stack. In other words, it will act essentially as an
NI module in the virtual chassis, passing traffic via
its Ethernet.
