Option 1 - Download Application Image and Write to HDD
Use Option 1 to download a version of the current application image from an FTP server location and write the image to the hard disk.
Note If the NAM application has already been installed and the network settings were configured, they will be automatically be detected by the helper. Otherwise, you must use Option n to configure the network before using this option.
This option downloads a version of the current application from an FTP server location or from a location you can access using HTTP. You can also download the latest NAM software version from Cisco.com.
This URL requires you to have a Cisco service agreement and access to the internet to download the zipped software.
Option 2 - Download Application Image and Reformat HDD
Use Option 2 to download the current application image and write the image to the hard disk.
Caution
Using this option reformats the hard disk before writing the application image and will destroy all data such as reports, packet captures, and configuration. Network connectivity configuration, however, will be retained.
