Alarm Card

The Alarm Card object is a child of the MetaSwitch object. There are two instances of the Alarm Card object for each instance of the MetaSwitch object ('Alarm card on Shelf A' and 'Alarm card on Shelf B'). Each instance of the Alarm Card object corresponds to a physical alarm card in the MetaSwitch chassis, and monitors the state of the shelf in which the card is located.

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

Note that the Shelf state must be MetaSwitch running and the Alarm card state must be Ready (indicating that the MetaSwitch software is running and has completed initialization) before any of the other fields in this object are valid.

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 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.
  • Power off when OS unreachable
    The shelf has been asked to switch power off, but the alarm card does not know the state of the OS because the periodic heartbeat from the OS has not been received for some time.
Alarm card state Read only The state of the alarm card on this shelf. The remaining fields are valid only if this field is set to Ready. Values:
