    Clearing an OduMism Alarm

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

    1. Ensure the ODU endpoints at both ends of the fiber are the same ODU type (that is, ensure both are ODU2 or both are ODU2e or both are ODU4). For information, see the BTI7800 Series Software Configuration Guide.
    2. Check for alarms on the local interface.
      • If the alarm clears, you have completed this procedure.
      • If the alarm does not clear, contact your next level of support.
