Reset button
The reset button has three functions:
• Release the button when green LED starts flashing, to reset RouterOS configuration to defaults.
• Release the button when the LED turns solid green to clear all configuration and defaults.
• Release the button after LED is no longer lit (~20 seconds) to cause a device to look for Netinstall servers
(required for reinstalling RouterOS over the network).
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. Useful for RouterBOOT debugging and recovery.
Operating System Support
The device supports RouterOS software with the version number at or above what is indicated in the RouterOS
