Restarting SonicWALL Appliances Some SonicWALL GMS changes require the SonicWALL appliance(s) to automatically be restarted after changes are applied. However, there might be instances when you want to restart the SonicWALL appliance(s) manually. To restart one or more SonicWALL appliances, complete the following steps: 1 Expand the System tree and click Tools. The Tools page displays. 2 To restart the selected SonicWALL appliance(s), click Restart SonicWALL. NOTE: We recommend restarting the SonicWALL appliance(s) when network activity is low.
