Managing OmniSwitch 6450 Stacks

Expansion Modules and Stacking Mode Detection

By default, 24- and 48-port OmniSwitch 6450 switches are set to stackable mode.
Note. 10-port OmniSwitch 6450 switches do not support stacking and operate in standalone mode only.
The switch's stacking mode (stackable versus standalone) is configured through auto-detection. During
the boot process, the switch determines the type of expansion module installed and sets the stacking
mode accordingly.

Swapping Expansion Modules

A reboot is required when adding or swapping "unlike" module types (e.g., a 10G stacking module is
being swapped with a 1G uplink module) or when a 1G uplink module is being added to an empty module
slot. Refer to the table below for more information:

Note. Because the switch uses auto-detection to determine whether stacking mode is needed, the
stack set slot mode
