If you click Reboot, you will receive the warning message shown in Figure 9.3a and your browser color will change to red to indicate that you have selected an option that will negatively impact users of the FreeNAS® system.
Figure 9.3a: Reboot Warning Message
Click the Cancel button if you wish to cancel the reboot request. Otherwise, click the Reboot button to reboot the system. Rebooting the system will disconnect all clients, including the web administration GUI. The URL in your web browser will change to add /system/reboot/ to the end of the IP address. Wait a few minutes for the system to boot, then use your browser's back button to return to the FreeNAS® system's IP address. If all went well, you should receive the GUI login screen. If the login screen does not appear, you will need physical access to the FreeNAS® system's monitor and keyboard so that you can determine what problem is preventing the system from resuming normal operation.
