Image Upgrade (NAM-1, NAM-2)

The NAM-1, NAM-2 cards utilize two images: a maintenance image and an application image. The

maintenance image allows the NAM to be loaded with a basic operating system to perform maintenance

tasks such as upgrading the application image. The application image contains both the NAM operating

system and the NAM traffic analysis software. Either of these images can be updated by simply rebooting

the NAM with the image you are not upgrading.

In other words, to update the application image:

1. Reset/reboot the NAM using the maintenance image.

2. When the proper image is loaded, connect to the NAM CLI and issue the update command with the

ftp URL where the new image is stored as the command parameter.

3. Follow all prompts.

4. Exit the CLI.

5. Finally, reset the NAM to use the application image (default for a reset).

Note(s):

• To determine which image the NAM is using, you can use the show module command or session into

the NAM. When using the application image, the show module output will indicate the software

version being used by the NAM. If using the maintenance image, the software version number will not

be the NAM release version and should be followed by an “m.” If the NAM is booted using the

maintenance image, the banner displayed when a session to the NAM is created will indicate that the

maintenance image is being used.
