-====== Remote power ======+====== Remote Power On of Devices ======
  
-===== Description =====+===== Service Description =====
  
-Power on (and off) computers remotely from a web page.+Powering on (and off) devices remotely via the web.
  
-With this service it is no longer necessary to leave your computer switched on in case you could need it at night, over the weekend or when traveling.+With this service, you do not need to leave your device on if you think you may need to use it at night, on weekends, or during an extended absence.
  
-<note important> In order to be able to power on your computer remotely it needs to have the **Wake on Lan** option activated. It is usually on by default, but it is wise to test it locally before trying to use this service for the first time from the outside.</note>+<note important>For the power-on system to work, the device must have **Wake on LAN** enabled. Many of the devices managed by the TIC Infrastructure Management Unit already have it enabled, but we recommend testing if it works the first time.</note>
  
-===== Access =====+===== Access to the Service =====
  
-The service can be accessed at https://apps.citius.usc.es/wakeonlan/.+The service is accessible via the URL https://apps.citius.usc.es/wakeonlan/. 
 +===== User Manual =====
  
-===== User manual =====+A list of the devices you are allowed to power off or on will appear, along with their current status. The devices that will appear are your own device (maximum one device per socket) and servers that have automatic shutdown, can be powered on using this system, and you have been granted access.
  
-When loading the web page a list of the computers you are allowed to power on or off will appear and as their actual power status will be shown. You should see at least your own computer (max. one computer per jack) as well as any server with automatic power off configured and to which you have access granted. +Depending on the status of each device, you can power on or off the device:
  
-{{ :centro:servizos:wakeonlan_1.png?nolink |}} +  * Off indicator (gray): The device is off; you can turn it on by pressing the button. There is no way to detect if the device powers on correctly until it boots, so the application will wait one minute before attempting to check the device's status again, and then it will recheck. If the device remains off (gray), it is likely that Wake on LAN is disabled in the BIOS or on the network card. 
-Dependent on the current status of each computer you will be able to power them on or off:+  * On indicator (static blue): The device is on; you can turn it off by pressing the button. Only devices with Ubuntu 18.04 from CITIUS can be turned off using this system. Other devices will receive an error when trying to turn them off. Servers with automatic shutdown cannot be turned off manually, and the button will appear grayed out. 
 +  * Working indicator (blue in motion): The device is being powered on or off at the moment, and you cannot do anything. The indicator will be in this state for one and a half minutes after powering on or off the device.
  
-  *  Off indicator(grey): Computer is switched off, you can send the power on signal to it pressing the button. There is no way of knowing whether it powers on correctly until it has finished off booting, so the service checks the computer status in one minute intervals. If after a while the status indicator is still off(grey) then the computer probably has the wake on lan option deactivated in the BIOS or in the network interface. +<note important>Shutdown is only supported on systems with the **Ubuntu from CiTIUS**.</note>
-  * On indicator (fixed blue): Computer is powered on, you can switch it off pressing the button. Only works in computers that have the CITIUS Ubuntu installed, others will show an error message. Servers with automatic power off configured can't be manually switched off and the button will be grayed out.  +
-  * Working indicator (flashing blue): The computer is being switched on or off presently and nothing can be done. The indicator will remain like this for a minute and a half after switching on or off the computer. +
  
-<note important> Some computers can't be switched on or off and so they will appear with a grayed out indicator once powered on if they can not be powered off and vice versa. Even though the power off button can appear active for desktop computers it will only work right when the operating system installed is the CITIUS Ubuntu.</note>+Press the ''Logout'' button to log out of the application.
  
-Press the ''Logout'' button to close the current session.+===== Changes =====
  
-===== FAQ =====+==== Version 1.3 ==== 
 +  * Support for shutdown on Ubuntu 18.04.
  
-==== After pressing the power on button the blue indicator flashes and then it shows the power off indicator again ==== +==== Version 1.2 ====
-This can happen for several reasons: +
-  * The computer is stuck in some point at the boot sequence (BIOS, GRUB menu, etc.) and needs manual intervention.  +
-  * The computer is disconnected from the network. +
-  * The computer has incorrectly configured Wake on lan.  This can happen the first time you use this service. Get in touch with IT Infrastructure Unit using [[citius.tic@usc.es]]. +
-  +
-==== After pushing the Power on button the blue indicator flashes, the power off indicator appears for a few seconds and then finally the Powered on indicator appears ==== +
-The system has no mean to verify that the computer is really booting, that's why after sending the power on signal it waits for a minute and a half before showing its real status. If it takes more than that amount of time to boot up it is possible that before showing the correct powered on status the indicator briefly shows that the computer is powered off.   +
  
-==== After pressing the Power off button, the blue indicator flashes for a while and then shows back the Power off button. ==== +  * Recognizes the login from the main page of the center http://citius.usc.es/, so if you are logged in there, it is not necessary to log in again. 
-This can happen when the computer hangs during the power off and requires manual intervention.+  * 1.2.3: Directly uses the center's login form if you are not logged in.
  
 +==== Version 1.1 ====
  
-==== The Power on/off button is grayed out and can't be pressed ==== +  * If the device cannot be turned off or on, it does not appear in the list. 
-Some computers can't be powered on or off and can have the button disabled depending on the allowed actions.+  * If the device cannot be turned off, the shutdown button does not appear. 
 +  * If the device cannot be turned on, the power-on button does not appear. 
 + 
 +===== Frequently Asked Questions ===== 
 + 
 +==== After pressing the power-on button, the moving blue indicator appears and then returns to the off indicator ==== 
 +This may be due to several causes: 
 +  * The device is stuck in some boot sequence (BIOS, Grub menu, etc.) and requires manual intervention. 
 +  * The device is not connected to the network. 
 +  * The device is not correctly configured for Wake on LAN. This can happen the first time you try the tool. Notify the TIC Infrastructure Management Unit at [[citius.tic@usc.es]] to take a look at your device's configuration. 
 + 
 +==== After pressing the power-on button, the moving blue indicator appears, then returns to the off indicator for a few seconds, and then the on indicator appears ==== 
 +The system has no way to check if the device is really turning on, so after sending the power-on signal, it waits a minute and a half before displaying the actual status again. If after that minute and a half the device still hasn't turned on but does later, it is possible that the indicator will return to the off state for a few seconds and, once powered on, will finally show the correct status. 
 + 
 +==== After pressing the shutdown button, the moving blue indicator appears and then returns to the on indicator ==== 
 +This may be due to the system being stuck in some shutdown sequence and requiring manual intervention. 
 + 
 +==== The power on/off button appears grayed out and I cannot click on it ==== 
 +Some devices cannot be powered off or on, and if they are on or off, the button will be disabled, depending on the actions that are permitted. 
 + 
 +==== My device does not appear in the list of devices I can power on/off ==== 
 +Notify the TIC Infrastructure Management Unit at [[citius.tic@usc.es]]. Devices are assigned manually, and there may be an error.
  
-==== My computer is not listed among the computers that can be powered on/off ==== 
-Warn the IT Infrastructure Unit [[citius.tic@usc.es]]. Computers are assigned manually and there could be errors.
