Please try performing a hard factory reset first by following the below steps.
Remove power from the switch.
Press and hold the Reset button while applying power to the switch.
After all the system LEDs flash amber, release the Reset button.
When all the system LEDs blink green, all the configuration data are erased and the switch is returned to its factory configuration. When all the system LEDs are solid green, the erase process is complete and the system reloads. Once reloaded and the SYST LED is steady green, the factory reset is complete.
