G-1000 User’s Guide

Note: Do not turn off the G-1000 while configuration file upload is in progress.

After you see a “restore configuration successful” screen, you must then wait one minute before logging into the G-1000 again.

Figure 44 Configuration Upload Successful

The G-1000 automatically restarts in this time causing a temporary network disconnect. In some operating systems, you may see the following icon on your desktop.

Figure 45 Network Temporarily Disconnected

If you uploaded the default configuration file you may need to change the IP address of your computer to be in the same subnet as that of the default G-1000 IP address (192.168.1.2). See your Quick Installation Guide for details on how to set up your computer’s IP address.

If the upload was not successful, the following screen will appear. Click Return to go back to the Configuration screen.
