Changing the Secondary Module to Primary
If there are only two switches in the stack, the former primary switch resumes the secondary role when it
comes back up following the takeover.

In this stack of two OmniSwitch 6800 Series switches, the slot 1
1
switch is the primary management module. The slot 2 switch is
the secondary.
A takeover is initiated by the user; the primary management
2
module is automatically reloaded. Any data flow on the primary
switch's Ethernet ports is interrupted.
The secondary switch takes over the primary role. Ethernet traffic
3
on slot 2 remains unaffected. Meanwhile the stack has no interim
secondary management module as the switch reboots.
When the former primary switch comes back up, it assumes the
4
secondary management role within the stack.
