Renumbering the Stack
If the units are no longer numbered sequentially after several topology changes or
failures, you can reset the unit numbers using the “Renumbering” command. Just
remember to save the new configuration settings to a startup co nfiguration file prior
to powering off the stack Master.
Command Usage
• The startup configuration file maps configur ation setti ngs to each swi tch in the
stack based on the unit identification number. Y ou should theref ore rememb er to
save the current configuration after renumbering the stack.
• For a line topology, the stack is numbered fro m top t o bottom , wit h the f irs t unit i n
the stack designated at unit 1. For a ring topology, the Master unit taken as the t o p
of the stack and is numbered as unit 1, and all other units ar e number ed
sequentially down through the ring.
