Changing the Secondary Module to Primary Managing OmniSwitch 6850 Series Stacks

page 4-36 OmniSwitch 6850 Series Hardware Users Guide April 2010

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 6850 Series 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 management

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. Meanwhile the stack has no interim

secondary management module as the switch reboots.
