Steps to take when reinstalling the NGFW software

Overview

Changing or upgrading hardware and now you need to do a fresh install of the Edge Threat Management NG Firewall software?

These are the steps you should take. Please note that the reinstall must be completed in-person, with physical access to the hardware you're installing onto. (You cannot reinstall remotely.) We recommend having a keyboard, mouse, and monitor connected to the hardware while reinstalling to an appliance which has appropriate ports.

1. Create a Configuration Backup of your custom settings and rule sets

2. Download and install the software

3. Connect to your appliance via serial console or video
   If your appliance supports video output, you can connect a standard monitor with a keyboard and mouse to perform the software installation. If your appliance supports serial console such as an Arista Q4, Q8, and Q8W, you need to follow the instructions to connect a serial console to your appliance.
   
   
4. Installing the NG Firewall software
   After you prepare the USB installer image on a USB drive, insert the disk into your appliance and boot. The installer will automatically run. Once the installer completes, remove the disk and reboot. Note that if you are using a custom appliance, you may need to modify the boot order of your appliance to make sure the USB drive is the primary boot device.
   
   
5. ⚠️ Untangle or Arista hardware only: install the hardware package as described below.

Hardware appliances

When reinstalling on an Arista ETM hardware appliance, you will need to reinstall the hardware package after the software installation completes. This is necessary so ETM Dashboard recognizes the hardware, as well as to enable the front-panel LCD on models which include one.

Installing the package

Locate your model in the table below to find the appropriate command for your appliance model and run this command from the command line. If you receive an error message indicating that a package was not found, run apt-get update first.

When to contact Support

If your model is not listed here; if you're not able to access the command line; or you are not familiar with its use; please contact the ETM Support team for assistance.
