Alarm Flag

To-Alarm-Box Flag

The to-alarm-box flag controls whether the alarms are reported to the alarm box or not.

• Report

  In Report status, the LMT drives the alarm box to enable the audio and visual alarm function.

• Not report

  In Not report status, the alarm box will not be activated when an alarm is generated or when the alarm status changes.

NOTE:

The to-alarm-box flag is used for fault alarms only. Event alarms are not reported to the alarm box.

Whether alarms are reported to the alarm box depends on the settings of to-alarm-box flag and the shield severity of the alarm box. Alarms are reported to the alarm box only when the to-alarm-box flag is set to Report and the alarm severity is greater than or equal to the shield severity of the alarm box.

Shield Flag

The shield flag is set to shield the alarm information not required. The shield flag can be set to Shielded or Unshielded.

• Shielded

  A board does not report the alarms whose shield flags are set to Shield to the network manager or the alarm box. The server does not save the logs of such alarms.

• Unshielded

  A board reports the alarms whose shield flags are set to Shield to the network manager or the alarm box. The server saves the logs of such alarms.

Modification Flag

The modification flag records the modification status of alarm configuration information. The status of modification flag is Modified or Unmodified.

• Modified

  After the alarm configuration is modified through a modification command, the modification flag is set to Modified.

• Unmodified

  When an alarm is in default setting or recovered to the default setting, the modification flag is set to Unmodified.

Alarm Cleared Flag

The alarm cleared flag indicates whether a fault alarm is cleared or not. The status of the alarm cleared flag is Not Cleared or Cleared.

• Not Cleared

  The fault alarm is not cleared.

• Cleared

  A recovery alarm is received and the fault alarm is cleared.
