Setup and Access to the BootROM

  1. Remove all power cords from the power supply switch. There should be no power to the switch.
  2. Insert the FAT formatted USB memory drive into the bottom USB port (labeled USB-1) of the MM installed in the slot you wish to recover.
  3. If present, remove the MM from the other management slot. Place the MM in a safe location and do not reinstall it until you finish recovering the switch.
  4. Attach a rollover serial cable to the console port of the MM still installed.
  5. Attach the other end of the serial cable to a properly configured terminal or terminal emulator.
    The terminal settings are:
    • 9600 baud
    • 8 data bits
    • 1 stop bit
    • no parityXON/OFF flow control enabled
  6. Provide power to the switch by re-inserting the power cords into the power supplies.
  7. Immediately press the spacebar until the BootROM -> prompt appears.
