• Use the Ethernet submenu to load and run a system software image and upgrade the BootWare.
• Use the BootWare Operation menu to upgrade the BootWare from the console port.
• Use the BootWare Operation menu to upgrade the BootWare from the Ethernet port.
• At the CLI, use the boot-loader file command to load and run a system software image and
upgrade the BootWare.
