There is a rather severe problem with connecting a UPS directly to a Mac OS Server. (not MacOSX Server, but any Mac acting as a server) You might wonder why you wouldn’t want to just connect the UPS to the computer? It will shut it down properly then and all will be well. Except that if you have the energy saver preferences set up to properly shut down your computer then it will not restart when the power comes back. There is a setting for most Macs to “restart after a power failure” but this only works if you let the power actually be pulled and NOT do a proper shutdown. The bug in MacOS is that this doesn’t work if you have a UPS connected to the machine! This has been broken for several major OS versions now. If you are running a Mac server and wish to use a UPS then you don’t actually want the UPS connected to the Mac or it will not restart without you there to push the button. | There is a rather severe problem with connecting a UPS directly to a Mac OS Server.

**Error**: sometimes the software will append an error message to the status line. I have seen “LOWBATT” when my ups battery wasn’t going to be able to service the high load. This unit will display either “none” or the message sent. It will be off as long as there is no error and will turn on to alert you that the UPS has sent some error message. Use the On script to notify yourself of an error message from the UPS. Note that this is not the same as a failed battery self test, that message handled separately see the “Self Test Failure” unit below. | **Error**: sometimes the software will append an error message to the status line.

**Self Test Failure**: If no self test has been run since the program connected then this unit will be in an off state and show “none”. Once a test has been run while it’s watching the unit label will change to “OK” unless there is a problem. If a self test failure of the battery or the load or whatever happens the label will change to the error message and the unit will turn on.

+ | **On Battery**: When the power has been out long enough for the UPS to be sure it isn’t a self test this unit will turn on. This is usually 5 or 6 seconds after a power failure. This will not turn on for power failure events shorter than that duration. This could be useful as you might turn off loads that are plugged into the UPS that are not necessary in a long term power failure condition to reduce the load and increase the runtime. | ||

+ | |||
+ | If you have installed the user scripts above then you can trap all broadcast events from the UPS inside the Interface Script. In the Edit Interface window click the “Edit” button for the interface script. Then use the “Insert...” toolbar button to insert the “UPS Event Handler” The AppleScript code that is inserted will give you a full list of the known events though depending on your model there may be others that could be sent as well. | ||
+ | |||
+ | Some of the events are also reflected as Unit changes such as the power fail and error messages. Others can only be caught by installing this handler. | ||
+ | |||
+ | < | ||

+ | U P S E V E N T H A N D L E R | ||
+ | |||
+ | Called when the UPS sends a broadcast event. This is where you | ||
+ | can trap events other than those that have units associated | ||
+ | with them. In order to receive these you must have installed the | ||
+ | xtevent script on the raspberry pi. | ||
+ | |||
+ | EventName will be one of the following: | ||
+ | |||
+ | annoyme | ||
+ | If we were letting the UPS shutdown our machine this is the alert that it is about | ||
+ | to happen. The events scripts stop the shutdown from happening however. | ||
+ | changeme | ||
+ | The battery needs changing. If we were allowing system shutdown that would happen next. | ||
+ | This event also turns on the ERROR unit. | ||
+ | commfailure | ||
+ | The UPS is no longer responding, possibly unplugged the USB cable? | ||
+ | This event also turns on the ERROR unit. | ||
+ | commok | ||
+ | Only sent after a commfailure event, the UPS is now responding. | ||
+ | doshutdown | ||
+ | When the config time limits or battery levels have dropped to the point that if it | ||
+ | were automatically going to shutdown it would now be doing so. | ||
+ | emergency | ||
+ | While in the software, nobody knows what would generate an emergency shutdown. | ||

+ | The batteries are exhausted. The next event will be doshutdown. | ||
+ | loadlimit | ||
+ | The battery charge is below the low limit set in the config file. | ||
+ | The next event will be doshutdown | ||
+ | powerout | ||
+ | This is sent immediately when the power fails. It can also be generated during | ||
+ | a self test of the UPS. | ||
+ | onbattery | ||
+ | Send 5 or 6 seconds after the powerout event if the power has not returned. | ||
+ | This could be used to filter self test events. The timing of this can be set | ||
+ | in the config file. | ||
+ | offbattery | ||
+ | Send when power returns but only if the power has been off long enough to generate | ||
+ | the onbattery event. | ||
+ | mainsback | ||
+ | The power has returned | ||
+ | runlimit | ||
+ | The Time Left property of the battery has fallen below the configured value. | ||
+ | timeout | ||
+ | The maximum time on battery value in the configuration has expired. | ||
