Managing OmniSwitch 6350 Stacks Changing the Secondary Module to Primary
OmniSwitch 6350 Hardware Users Guide April 2017 page 7-35
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.
