Installing the Smoothwall Classroom Manager Chrome Extension on Your Devices Using Google Admin

Disclaimer: Correct as of September 2019. This article only contains guidance on how to deploy the Smoothwall Chrome extension to your Chromebooks. It is NOT a replacement for Google's online help on how to use their services, see Google's online help, Set Chrome policies for users or browsers.

To use Classroom Manager, you need to install the Smoothwall Chrome extension on all your students' devices. You should do this per user, NOT per device. Please use Google's online help to navigate their Admin Console and use this knowledge base article for the settings that you need to configure.

  • Teachers DO NOT need the extension installed on their devices for Classroom Manager to work.
  • However, in the Smoothwall Administration Portal you need to import your teachers from your Google Classroom account, which will send them an email with a link and login to the Teacher Portal.
  • If you have the Smoothwall Filter and Firewall, you need to allow Classroom Manager through the Smoothwall Filter. See our knowledge base article, Allowing Classroom Manager through the Smoothwall Filter.

Prerequisites

  • Retrieve your customer serial number, from the email that Smoothwall sent you after your purchase. It should start with "UNCL".
