Procedure 5-37: Clear "inc. OCN RFI-L/STMN MS-RFI" condition/alarm
Before you begin
Prior to performing this procedure:
-
Refer to Before you begin and Required equipment in this chapter.
-
Refer to Laser safety and Electrostatic discharge in Chapter 1, Safety.
Steps
Complete the following steps to clear an inc. RFI condition/alarm.
1 |
From the WaveStar® CIT System View, click the Alarm List button and locate the inc. RFI condition/alarm in the resulting alarm list. | ||||||
2 |
Important! The inc. RFI condition/alarm indicates that the far-end network element has detected a bad OC-N/STM-N signal from this network element. The inc. RFI condition/alarm is normally cleared by addressing other alarms/conditions. Are there other conditions/alarms in the alarm list?
| ||||||
3 |
From the System View, click the Alarm List button and click Refresh. | ||||||
4 |
Is the inc. RFI condition/alarm still present?
| ||||||
5 |
Refer to the Probable Cause column in the alarm list, determine the OC-N/STM-N line affected by the inc. RFI alarm, and note the corresponding AID. | ||||||
6 |
Visually check the local transmit fiber connections between the circuit pack faceplate and the LGX panel or equivalent connection point for faulty connections or damage.
| ||||||
7 |
From the System View, click the Alarm List button and click Refresh. | ||||||
8 |
Is the inc. RFI condition/alarm still present?
| ||||||
9 |
Disconnecting cables and/or replacing pluggable transmission modules may disrupt service. Before taking action, determine the extent of service disruption caused by disconnecting cables or replacing a pluggable transmission module. Then, perform the action(s) deemed appropriate in light of the traffic being carried and the nature of the failure. Replace the affected local pluggable transmission module. Reference: Procedure 6-6: Replace pluggable transmission module | ||||||
10 |
From the System View, click the Alarm List button and click Refresh. | ||||||
11 |
Is the inc. RFI alarm still present?
| ||||||
12 |
Disconnecting cables and/or replacing circuit packs may disrupt service. Before taking action, determine the extent of service disruption caused by disconnecting cables or replacing a circuit pack. Then, perform the action(s) deemed appropriate in light of the traffic being carried and the nature of the failure. Replace the affected local circuit pack. Reference: Procedure 6-4: Replace VLNC5x SONET/SDH transport circuit pack | ||||||
13 |
From the System View, click the Alarm List button and click Refresh. | ||||||
14 |
Is the inc. RFI condition/alarm still present?
| ||||||
15 |
Important! At this point, the local network element is operating correctly. The trouble is in the far-end network element or in the fiber/cable between the far-end network element and the local network element. Consult and follow local procedures for addressing OCN/STMN-related conditions/alarms at the far-end network element. | ||||||
16 |
From the System View at the local network element, click the Alarm List button and click Refresh. | ||||||
17 |
Is the inc. RFI condition/alarm still present?
| ||||||
18 |
Consult and follow local procedures to isolate and clear the fiber/cable trouble between the far-end network element and the local network element. End of steps |
