    It can take up to 20 minutes for the appliance to reboot and rejoin the grid. To confirm that the reboot is complete and that the node has rejoined the grid, go back to the Grid Manager. The NODES page should display a normal status (no icon) for the appliance node, indicating that no alerts are active and the node is connected to the grid.
