this section describes the procedure to boot a catalyst 9xxx series switch from the bootloader / rommon prompt with a usb flash drive or tftp server. in this method, the switch can only be booted into bundle mode. the switch does not copy the files you boot to the flash file system, nor is the option available. the switch administrator must copy the relevant files to flash after the switch is booted. if you need install mode, either convert the switch after successful boot in bundle mode, or use the steps described in option 3. 3d9ccd7d82
