  1. Retrieve PM statistics for the DOL OCH:
    show statistics current och:identifier
  2. Refer to DOL OCH power alarm thresholds to determine whether the optical power received is higher than the specified range for operation.
  3. If the optical power received is too high, add an attenuation pad in the optical path to bring the power down to a level within the specified range.
  4. Check for alarms on the DOL OCH.

    • If the alarm clears, you have completed this procedure.

    • If the alarm does not clear, contact your next level of support.
