OmniSwitch 6850 Series Hardware Users Guide

Reloading is essentially a soft boot of a switch. Users can reload stacked modules operating in any role—
i.e., primary, secondary, idle, and pass-through. Refer to the sections below for more information.

If the switch with the primary management role is reloaded, the switch with the secondary role automati-
cally takes over primary management functions. In other words, the switch with the secondary role 
assumes the primary role as soon as the reload is initiated. 

Meanwhile, the idle switch with the next lowest slot number automatically assumes the secondary role. 
When the reloaded switch (the former primary module) comes back up, it assumes an idle role within the 
stack.

To reload the primary management module, use the 

 command. The optional syntax primary can 

be used in the command line, but is not required. For example:

-> reload primary

Note. A primary management module reload can also be scheduled for a later time or date. For informa-
tion on scheduling a primary module reload, as well as additional command details, refer to the 
OmniSwitch CLI Reference Guide.

In this stack of four OmniSwitch 6850 Series switches, the slot 1 
switch is the primary management module. The slot 2 switch is 
the secondary. Slots 3 and 4 are operating in idle roles.

The user reloads the stack’s primary management module by issu-
ing the reload primary command. Any data flow on the primary 
switch’s Ethernet is interrupted.

The secondary switch automatically takes over the primary role. 
The idle switch with the next-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 2, 3, and 4 remains unaffected.

When the rebooted switch comes back up, it assumes an idle role 
within the stack.
