NBG4615 User’s Guide

The following table describes the labels in this screen.

Note: Do not turn off the NBG4615 while firmware upload is in progress!

After you see the Firmware Upload In Process screen, wait two minutes before 
logging into the NBG4615 again.

The NBG4615 automatically restarts in this time causing a temporary network 
disconnect. In some operating systems, you may see the following icon on your 
desktop.

After two minutes, log in again and check your new firmware version in the 
Status screen.

If the upload was not successful, an error message appears. Click Return to go 
back to the Firmware Upgrade screen.

Backup configuration allows you to back up (save) the NBG4615’s current 
configuration to a file on your computer. Once your NBG4615 is configured and 
functioning properly, it is highly recommended that you back up your configuration 
file before making configuration changes. The backup configuration file will be 
useful in case you need to return to your previous settings.
