===== ROMMON / bootloader =====

  Unplug the switch power cord, and press the switch Mode button while reconnecting the power cord. 
  You can release the Mode button a second or two after the LED above port 1X goes off. 
  You should then see the bootloader Switch: prompt.
  The bootloader performs low-level CPU initialization, performs POST, and loads a default operating system image into memory.
