Troubleshooting Tips

If no alarm messages are sent for an unusually long period of time, ping the AIC address to check for
connectivity.

Monitoring and Maintaining the NM-AIC-64 Contact Closure Network Module

The AIC provides a TFTP client for software upgrade and configuration image transfer. The methods
for both actions, as well as how to override the existing software or configuration, are described below.

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