UPS monitoring and automated safe shutdown using WinNUT

This faq deals with monitoring and shutdown of a PC or Server running a Windows operating system. For general UPS configuration refer to faq301.

• When editing the upsmon.conf file on the Windows system you will need to know the UPS Name, Username and Password that were setup in the Opengear’s UPS Connections page. In this example the UPS Name is “powercom”, the Username is “poweruser” and the Password is “password” 
  
   
  
  
• Download the current WinNUT client from http://code.google.com/p/winnut/downloads/list and install it on the Windows PC/Server
  
  
• You will have to edit the upsmon.conf to add the monitored UPS
  
  
• Click Edit
  
   
  
  
• Scroll down to the Examples: section and add a line as shown above, modify according to your values
  • The first part you need is “MONITOR”
  • The second part is your UPS name@Hostname/IP address of your Opengear console server that is connected to the UPS
  • Third is the number “1”, you will almost always use the number 1, refer to the notes for the section above in the upsmon.conf to determine if you need another value
  • Fourth is the Username
  • Fifth is the Password
  • Sixth is “slave”, you will always use slave not master
  
   
  
  
• You will need to setup WinNUT to either run at startup, or run as a service

Note in newer Windows operating systems, i.e Windows 7, you will need to right click on the WinNUT Configuration Tool icon and click on “Run as administrator” to be able to choose Install As Service option

• Finish all configuration of WinNUT Configuration Tool by clicking on the Apply and Start WinNUT button

Now when the UPS has gone to Critical power level, you will get a popup announcing that the system is being shut down.
