SUM_INPWR_HI

SUM_INPWR_HI

Description

The SUM_INPWR_HI alarm indicates that the input optical power is excessively high. The alarm occurs when the input optical power of the multiplexed signals exceeds the threshold.

Attribute

Alarm Severity Alarm Type

Major

Communication alarm

Parameters

None

Impact on the System

The optical modules of the boards at the local station and downstream station may be damaged. The services have bit errors, or are even interrupted.

Possible Causes

  • The output optical power of the board at the upstream station is normal and the power of the received optical signals accessed by the board at the local station is excessively high. The proper attenuation is not added.

  • The output optical power of the board at the upstream station or peer station is excessively high.

  • The board at the local station is faulty.

Procedure

  1. Check whether the input optical power of the input interface of the board at the local station is within the normal range by using an optical power meter. If the power is not within the normal range, add proper attenuation by placing a fixed attenuator or a VOA.
  2. If the alarm persists, check whether the output optical power of the board at the upstream stations is within the normal range by using the NMS. If the input optical power of the board at the local station is excessively high, handle the alarm according to the handling procedure of the IN_PWR_HIGH alarm. If the output optical power of the boards at the upstream stations is excessively high, respectively check whether the corresponding input and output optical power of each upstream station are within the normal range.
    • If the input and output optical power of the board at the upstream station are not within the normal range, adjust the input optical power to a value within the normal range.
    • If the input optical power of the board at the upstream station is within the normal range but the output optical power is not, the board at the upstream station may be faulty. Replace the faulty board.
  3. If the alarm persists, replace the faulty board.
