Create an Alarm Clock that Activates Once
The following procedure describes how to create a one-time alarm (applies to Release 8.0 and later releases). The wake–up mechanism performs the equivalent of a remote control power up command.
1. Create a local instance (see an example of the required format) of IPS_AlarmClockOccurrence with the following parameters:
Field | Format | Description |
StartTime | datetime | The value of the StartTime Datetime format requires a “T” between the date and the time and must end with “Z”. Seconds must be set to zero. For example: "yyyy-mm-ddThh:mm:00Z". The time must be later than the current time or the Set operation will be rejected. |
Interval | datetime | Set to zero. |
ElementName | string | A user-provided identifier. This must be unique among the defined alarms. The maximum length of the string is 32 characters. It cannot be left empty. |
DeleteOnCompletion | boolean | If true, Intel AMT will delete the instance of IPS_AlarmClockOccurrence once the alarm has occurred. |
2. Retrieve the instance of AMT_AlarmClockService, where the “Name” key equals “Intel(r) AMT Alarm Clock Service”.
3. Invoke the AMT_AlarmClockService.AddAlarm: method with the instance of IPS_AlarmClockOccurrence created in step 1 embedded as an input parameter. The method will succeed as long as there are currently fewer than five instances of IPS_AlarmClockOccurrence.
