I am at a location that has a new routeros setup, custom hardware. For unknown reasons the remote configuration failed to properly enter the key and didn't notice. The routeros software appears to employ the most brutal of responses to licensing, which is to simply power off. No pausing or prompting or offers to attempt at entering a key. The shutdown happens nearly instantaneously with the initial boot of the OS. Is there a hot key or something that i can press at boot up to give me a chance at entering a product key or do I have to pull the device and use something else instead?
