 The main power control panel shown below is displayed either through the command line or the Applications menus. In addition to power status there are several other status indicators. These indicators are described as follows:

 Selecting the node to control is done with the selection window shown below. Any combination of nodes can be powered on or off using this selection box. If a node is checked it will be powered on. If a node is not checked it will be powered off. The node name and the current status are indicated on the panel. Similar to the command line tools, if a node is already on (or off) setting it to on (or off), will have no effect.

-This window will indicate what will happen for each node. The power control choices can be changed by using the "Back" button. Once the choice is correct, entering "Yes" will start the power control operations. An indicator of which nodes are powering down will be displayed until they are finished. Like the command line tools, the shutdown will time out and cut power if the operating system's shutdown cannot be confirmed. The "Close" button does not stop the shutdown process.

If a node is **already running** it remains **on**, the node will not be restarted. If a node is **turned off**, it will power-down the node. If it is already **off** nothing will happen.
 At the end of the the power-up or power-down cycle, the main Power Control panel will display the current state of the system.

 ====Using the Relayset Program====
-The low level ''relayset'' utility is available to administrators, however it should only be used as a last resort. The node-power{on/off} utilities provide a much more controled and gracefull method of turning systems on and off.
