Cisco Cisco NetFlow Generation Appliance (NGA) 3340 Installation Guide

 lists the specifications for the power supply.

Cisco occasionally provides upgrades to NGA software you can download and install on your Cisco 
NetFlow Generation Appliance. You might also use the downloadable software to restore your appliance 
software in the case of a catastrophic failure. 

After you upgrade or restore your appliance software, if you have backed up your NGA configuration, 
you can restore that configuration and resume network monitoring without undue delay. 

This section contains the following sections: 

After you complete any changes to your NGA configuration, use the command line interface to 
upload your NGA configuration to an archive server. 

Use the command line interface to restore your previous NGA configuration. 

Download a version of the current NGA software and use a single CLI command to perform the 
software upgrade.

Use the helper utility to perform a recovery installation.

Before you begin the upgrade process, we recommend that you perform a complete backup of your 
current NGA configuration.
