Buttons

Reset button:

  • Hold this button during boot time until the USR LED light starts flashing, release the button to reset RouterOS configuration.
  • Hold the Reset button and power on your device (wait until the "USR" led is blinking then stable "On", and when the "USR" led is "Off" - release the Reset button) - the device is booting in bootp mode to reinstall RouterOS using Netinstall.
    The MGMT/BOOT Ethernet port (Ether1 or Ether2) is used for the Netinstall process. See RouterOS documentation about using the Netinstall recovery utility.

Regardless of the above option used, the system will load the backup RouterBOOT loader if the button is pressed before power is applied to the device.
