Software Upgrade
When upgrading software, the AIC must be reset to run the new software. The AIC provides a protected
(login required) command for software download. When the user invokes this command with the TFTP
server address as a parameter, the AIC connects to the IP address and, via TFTP, retrieves the software
image file. After verifying that the software has been transferred successfully, the AIC replaces its
running software with the newly downloaded software.

In the case of incompatible versions of IOS and AIC software, the IOS recognizes the difference and
displays this information to the user. The user makes the decision whether to upgrade or downgrade
either the IOS or AIC software or to take no corrective action.

Configuration Backup
AIC CLI provides commands for storing and restoring configurations. Users can transfer the current
configuration of the AIC to or from the TFTP server whose address is given as a parameter to the get
config command. When a configuration file is transferred from the server to the AIC, the AIC takes on
the new configuration.

config command. When a configuration file is transferred from the server to the AIC, the AIC takes on
the new configuration.
The configuration is stored as a list of commands (script) that can be applied to the CLI of an AIC for
configuration.
configuration.
Two other useful commands are get image and put config. Use get image to get a new image, and
put config to back up the configuration to the TFTP server.
put config to back up the configuration to the TFTP server.
Backup is not automatic, but the AIC will remind the user, upon logout, to back up the configuration.
Override
In the case that bad software is resident on the AIC or that the configured administrator password is lost,
the AIC provides a method for recovering the card. Upon booting, the AIC begins a countdown, visible
at the AIC local CLI (Craft Port). If an ASCII character is received on that local CLI channel (DSCC4
channel 2) during this countdown, the AIC enters a mode in which a limited CLI is available. At this
limited CLI, available over the Craft Port only, no login is necessary. The user may execute commands
for software upgrade and configuration transfer. The new configuration will take effect upon a reset of
the AIC card. See

for more information.
After interrupting the countdown, the user will see an “[AIC Boot]:” prompt. From this prompt, the user
can enter “?” to see the available commands, “g” to get a new application image, or “d” to delete the
current configuration and return to the defaults. (All commands require a carriage return.) In the case of
the get command, the user will be prompted for the name of the file, the IP address of the TFTP server,
and a confirmation.

Show Commands
The Cisco IOS show command can be used to display AIC configuration settings and the information
sent to the IOS by the AIC. The ping command is useful for verifying asynchronous line connectivity.
