Managing OmniSwitch 6250 Stacks Reloading Switches
OmniSwitch 6250 Hardware Users Guide June 2012 page 6-29
Reloading the Secondary Management Module
If the switch with secondary management role is reloaded, the idle switch with the lowest slot number will 
automatically assume the secondary role. The reloaded switch (the former secondary) will assume an idle 
role when it comes back up. 
Meanwhile, the switch with the primary management role, as well as any other idle modules in the stack, 
continue operations without interruption.
To reload the secondary management module, use the reload command. Be sure to include the syntax 
secondary in the command line. For example:
-> reload secondary
Note. A secondary management module reload can also be scheduled for a later time or date. For informa-
tion on scheduling a secondary module reload, as well as additional command details, refer to the 
OmniSwitch CLI Reference Guide.
Reloading the Secondary Management Module In a Stack of Three or More
In this stack of four OmniSwitch 6250 switches, the slot 1 switch 
is the primary management module. The slot 2 switch is the sec-
ondary. Slots 3 and 4 are operating in idle roles.
The user reloads the stack’s secondary management module by 
issuing the 
reload secondary 
command. Any data flow on the 
secondary switch’s Ethernet is interrupted.
The idle switch with the lowest slot number—in this case, 
slot 3—automatically becomes the secondary management 
module. The slot 4 switch remains unaffected. In addition, 
Ethernet traffic on slots 1, 3, and 4 remains unaffected.
