System Alarm Card

The System Alarm Card object is a child of the System Hardware object in an Integrated Softswitch or Media Gateway. It corresponds to a physical alarm card in the MetaSwitch chassis, and monitors the state of the Controller with which the card is associated.

There are no configurable fields, but the object displays summary status information about

In the event of any failure, first check the Alarm state field in this object, to determine whether this shelf requires maintenance action. If maintenance action is necessary, the other fields in this object give more detailed information on the cause of the problem.

Description
Power and operating system status Read only This field is used only for the AL3000 alarm card. It displays a combination of the desired power state and the state of the operating system (OS). The remaining fields are valid only if this field is set to Running. Values:
  • Off
    Shelf power is off.
  • OS not running
    Shelf power is on, but the OS is not yet running.
  • OS booting
    Shelf power is on, and the alarm card has detected that the OS is booting.
  • Running
    Shelf power is on, and the OS is running. The OS is sending periodic heartbeats to the alarm card to verify its status.
  • Shutting down
    Shelf power is on, the OS is still running, but the alarm card has been informed that the OS and application are shutting down.
  • OS unreachable
    Shelf power is on, the OS and application have been known to be running sometime in the past, but the current status is unknown because the alarm card has not received a periodic heartbeat from the OS for some time. When this state occurs the system will automatically reboot.
  • Power off when OS booting
    The shelf has been asked to switch power off and believes that the OS has booted but not to the point where the application is running.
  • Power off when running
    The shelf has been asked to switch power off when the OS is running.
  • Power off and shutting down
    The shelf has been asked to switch power off and the software has begun to shut down.
