Managing OmniSwitch 6450 Stacks Expansion Modules and Stacking Mode
OmniSwitch 6450 Hardware Users Guide September 2015 page 7-3
Expansion Modules and Stacking Mode
The switch’s stacking mode (stackable versus standalone) is configured through auto-detection for 24-port
and 48-port models. 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:
Determining Mode for 24-port and 48-port Models
Note. Because the 24-port and 48-port switches use auto-detection to determine which mode is needed,
the stack set slot mode command is not supported.
OmniSwitch 6450-10 Mode
Unlike the 24-port and 48-port models the OS6450-10 requires no expansion module and does support
auto-detection of the mode. The mode of the OS6450-10 can be manually configured using the stack set
slot mode as shown below:
-> stack set slot 1 mode stackable
The switch must be rebooted for the new mode to take affect.
