When you replace a node with a different switch type, you cannot
      continue to use the same stack configuration. The slot configuration for the replaced node
      must change to reflect the new switch type.
To
        replace a node with a different switch type, follow these steps:
    - 
        Use the show
            switch, show licenses, and show stacking configuration commands to display
          configuration information for the node to be replaced.
        
Note the following about the node you are
            replacing:
            - ExtremeXOS software version
 
            - Partition on which the switch is booted
 
            - Effective license level for the stack
 
            - Slot number
 
            - Master-capable feature configuration
 
            - Node priority
 
            - Alternate gateway IP address
 
          
 
       - 
        Enter the unconfigure slot slot
          command to remove the configuration for the node to be replaced.
        
All configuration parameters (except for the
          related node's NVRAM-based configurations such as stacking parameters, image to be used,
          and failsafe account) for the slot are erased.
       - 
        Remove the stacking cables from the node that is being
          replaced.
      
 - 
        Add the new node to the stack following the procedure in
            Manually Adding Nodes to a Stack.
