Chapter26 Managing Configuration Files, System Images, and Functional Images
Maintaining Functional Images (Catalyst8540 MSR)
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.

Additional File Transfer Features

The following file configuration file transfer options are also available:
Configure the ATM switch router as a TFTP server to provide other devices on the network with
system images and configuration files.
Configure the ATM switch router to use the remote copy protocol (rcp) and remote shell (rsh)
protocol—With rsh you can execute commands remotely; with rcp, you can copy files to an d from
a file system residing on a remote host or network server.
Maintaining Functional Images (Catalyst 8540 MSR)
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.

Understanding Functional Images (Catalyst 8540 MSR)

Functional images provide the low-level operating functionality for various hardware controllers. On
hardware controllers with insystem programmable devices, such as field programmable gate arrays
(FPGAs) and Erasable Programmable Logic Devices (EPLDs), the hardwa re functional images can be
reprogrammed independently of loading the system image and without removing the devices from the
controller.
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 networ k
clock modules.
All new hardware is shipped with functional images preloaded. Loading a different functional image is
required only when upgrading or downgrading functional imag e versions.

Loading Functional Images (Catalyst 8540 MSR)

You load a functional image in two steps:
Step1 Copy the image to a Flash memory device (bootflash, slot0, or slot1). For in structions on copying files
to a Flash memory device, refer to the Configuration Fundamentals Configuration Guide.
Step2 Load the image from the Flash memory device to the hardware controller.
Note The command for loading functional images on th e ATM switch router differs from that described in the
Cisco IOS documentation.
