    Clearing an EnvVoltHighTh Alarm

    Note: Follow all applicable safety requirements as described in the BTI7800 Series Hardware Overview and Installation Guide.

    Note: Refer to the BTI7800 Series Software Configuration Guide before rebooting a traffic module or to the BTI7800 Series Hardware Overview and Installation Guide before reseating (removing and reinstalling) or replacing equipment or traffic modules.

    1. Retrieve environment information to view voltage readings for the equipment or traffic module:
      show environment voltage
    2. Do the following:
      • If the alarm is raised against the equipment, go to step 5.
      • If the alarm is raised against a traffic module, go to the next step.
    3. Perform a warm reload of the traffic module.
      system reload warm module
      • If the alarm has cleared, you have completed this procedure.
      • If the alarm does not clear, go to the next step.
    4. Perform a cold reload of the traffic module.
      system reload cold module
      • If the alarm has cleared, you have completed this procedure.
      • If the alarm does not clear, go to the next step.
    5. Reseat the equipment or module.
      • If the alarm has cleared, you have completed this procedure.
      • If the alarm does not clear, go to the next step.
    6. Replace the equipment or module.
    7. Check for alarms on the equipment or module.
      • If the alarm has cleared, you have completed this procedure.
