2.5.1.5  Config Mismatch 
A “Config Mismatch” in the Switch Status column indicates inconsistent entries in the “Preconfigured 
Model Identifier” and “Plugged-in Model Identifier” columns.  This usually occurs after a renumbering of 
units when the stack consists of multiple models, but can also occur after a new unit is added to the stack 
when the stack has been preconfigured and expects a different switch model.  The command below 
shows a Config Mismatch with a preconfigured model of N4032F and a plugged-in model of N4032 for 
Unit 3.
