Configure custom settings

Use a USB drive to apply custom network settings to a Guardian Air device. Define static IP address, gateway, DNS, and proxy server parameters in a configuration file. Load the file during device startup to configure networking manually.

Before you begin

Make sure that:
  • Your Guardian Air device is running firmware version 1.0.14 or later
  • You have a universal serial bus (USB) drive formatted as FAT32

About this task

Within certain limitations, it is possible to customize the configuration of a Guardian Air device. To do this, you must copy a configuration file to a FAT32-formatted USB pendrive. Then, before you power-on the device, you must connect the USB pendrive to one of the USB ports on the device.

For more details, see Custom settings configuration.

Procedure

  1. Connect a USB pendrive to a desktop or laptop computer.
    Note:
    The operating system (OS) installed is not important.
  2. Format the USB pendrive.
  3. Assign the label NOZOMI to the USB pendrive.
  4. On the USB pendrive, create a file with the name: configuration.ini
  5. Open the configuration.ini file.
  6. In the configuration.ini file, enter this text: 
    [network]
  7. Enter a line for each parameter that you want to customize. For example, 
    [network]
address=172.16.4.195/26
gateway=172.16.4.193
dns=172.16.4.193
http_proxy=http://10.41.48.40:3128
https_proxy=http://10.41.48.40:3128
ntp_servers=time.google.com,time.aws.com,time.cloudflare.com
  8. Save the configuration.ini file.
  9. Safely eject the USB pendrive.
  10. If the Guardian Air device is powered on, disconnect the electrical power cable.
  11. Connect the USB pendrive to one of the USB ports on the Guardian Air device.
  12. To turn on electrical power to the Guardian Air device, connect the electrical power cable.
  13. Wait until the status light-emitting diode (LED) indicator starts to flash green.
    This means that the Guardian Air custom network configuration has been correctly applied, and the system is able to connect to the Nozomi Networks cloud service.
  14. If the LED does not flash green, see the Troubleshooting section.
  15. Safely eject the USB pendrive.

Guardian Air is now configured with your custom settings.
