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.
Takeover Behavior In a Stack of Two
In this stack of two OmniSwitch 6350 switches, the slot
1 switch is the primary management module. The slot 2
switch is the secondary.
A takeover is initiated by the user; the primary man-
agement module is automatically reloaded. Any data
flow on the primary switch’s Ethernet is interrupted.
The secondary switch takes over the primary role.
Ethernet traffic on slot 2 remains unaffected. Mean-
while the stack has no interim secondary management
module as the switch reboots.
