How can i remove switch modus on rb 493AH
What do you mean by “switch modus”? By default RB493AH ports are not switched.
Maybe he is asking for the “switch chip”.
No you can’t remove it, but you can remove the switched ports from configuration through the winbox interface or CLI
Thanks for your answers.

No, the 493 has 10/100mbit ports, the 493G instead has gigabit ports.
You can always reset the config with
/system reset-configuration
And if when the system boots show a mesage to remove config, just remove it, and the router will be clean as a baby 
i have done, system reset-configuration
the switch mode stay enabled
Tnx fot reply
Switching mode is configured by setting master-port. If master is not set there is no switching.
