Your WebBrick Gateway should automatically start on power-up of the operating platform, if this is not the case then your installer should have shown you how to start the WebBrick Gateway. Depending on the version of hardware this may take up to 5 minutes.
The appliance version will shut down when the front panel power switch is pushed briefly.
Even though the WebBrick Gateway has started, it can take up a further two minutes for the WebBrick Gateway to discover the WebBricks on your network and for all user displays to be complete.
