Inc. All rights reserved. You can load functional images used by certain hardware controllers in the ATM switch router. This section describes the function and maintenance of functional images. Functional images provide the low-level operating functionality for various hardware controllers. Note You can currently reprogram the functional image on the channelized DS3 and channelized E1 Frame Relay port adapters.
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. Note The command for loading functional images on the ATM switch router differs from that described in the Cisco IOS documentation. The reprogram command checks the compatibility of the image for the selected card type before downloading the functional image.
