Entering Commands at the Boot Prompt

If the Boot> prompt appears on the serial console instead of the Local> prompt, one of two things may be wrong. Either the ETS does not have enough information to boot, or the network or flash boot has failed. If pressing the Return key does not display a prompt, press any other key. The Boot> prompt should appear.

If the ETS does not have enough information to boot, or the network or flash boot has failed, it will print a message to the console and wait ten seconds for serial port activity. If it detects no serial port activity, it will continue booting provided the flash is good. However, if the user presses a key during that time period, the ETS will display the Boot> prompt.

Note: If you see the message “Will attempt another download in x minutes,” press any key for the Boot> prompt.
