DRIVER/2/CARDOPTICALRXPOWERHIGH

1. Run the display interface command in the user view to check the current Rx power of the interface.

• If yes, go to Step 8.
• If not, go to Step 2.

2. Check whether an alarm indicating that the transmit optical power is too high is generated at the opposite end.

• If yes, go to Step 3.
• If no, go to Step 4.

3. If the peer alarm is cleared first, go to Step 9.

4. Check whether the peer optical module matches the local optical module.

• If they do not match, go to Step 5.
• If yes, go to Step 6.

5. Replace the optical module that matches the peer end. Then, go to 9.

6. Add an optical attenuator at the local end. It is recommended that the optical attenuator be increased by –5 dB.

• If the fault is rectified, go to Step 9.
• If the fault persists, go to Step 7.

7. Replace the optical module.

• If the fault is rectified, go to Step 9.
• If the fault persists, go to Step 8.

8. Collect alarm, log, and configuration information and contact technical support.

9. End.
