Managing OmniSwitch 6855 Series Stacks Slot Numbering Manual Slot Number Assignment To manually assign slot numbers to one or more modules in a stack, use the stack set slot command. This command writes slot information to the boot.slot.cfg file located in a switch's /flash directory. It is this saved slot information that the switch will assume following a reboot. Manually assigning slot numbers can be useful in reordering existing slot numbers in order to create a sequential numbering scheme from the top of the stack to the bottom (or vice-versa). Refer to the following example: Slot 6 - Idle Slot 7 - Idle Slot 8 - Idle Slot 1 - Primary Slot 2 - Secondary Slot 3 - Idle Slot 4 - Idle Slot 5 - Idle Note: The diagram above is for example purposes only, currently only four OS6855-U24X switches can be stacked at a time. This example, taken from page 7-21, shows a stack in which the primary and secondary switches are physically positioned in the middle of the stack. Although the stack will operate normally with this primary and secondary module positioning, it may be preferable for management purposes to have the primary and secondary switches at either the top or the bottom of the stack. For this example, the primary and secondary roles will be assigned to the top of the stack. This is accomplished by entering the following commands: -> stack set slot 6 saved-slot 1 -> stack set slot 7 saved-slot 2 -> stack set slot 8 saved-slot 3 -> stack set slot 1 saved-slot 4 -> stack set slot 2 saved-slot 5 -> stack set slot 3 saved-slot 6 -> stack set slot 4 saved-slot 7 -> stack set slot 5 saved-slot 8 -> reload all OmniSwitch 6855 Series Hardware Users Guide September 2011 page 7-23
