Copy images between local Flash memory devices. You can enter multiple boot commands in the startup configuration file or in the BOOT environment variable to provide main and alternative methods for loading a system image onto the ATM switch router. Enter ROM monitor mode or manually load a system image from ROM monitor if a valid system image is not found or if the configuration file is corrupted. You can load functional images used by certain hardware controllers in the ATM switch router. This section describes the function and maintenance of functional image.
Functional images provide the low-level operating functionality for various hardware controllers.
On the ATM switch router, you can reprogram the functional images on the route processors, rommon, switch processors, switch processor feature cards, carrier modules, full-width modules, and network clock modules. All new hardware is shipped with functional images preloaded. Loading a different functional image is required only when upgrading or downgrading functional image versions. For instructions on copying files to a Flash memory device, refer to the Configuration Fundamentals Configuration Guide . Step 2 Load the image from the Flash memory device to the hardware controller.
