Procedure 5-69: Clear "inc. OCN RFI-L" alarm

Overview

This procedure is used to clear an inc. OCN RFI-L 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. OCN RFI-L alarm.

From the WaveStar^® CIT System View, click the Alarm List button and locate the inc. OCN RFI-L alarm in the resulting alarm list.

Important!

The inc. OCN RFI-L alarm indicates that the far-end network element has detected a bad OC-N signal from this network element. The inc. OCN RFI-L alarm is normally cleared by addressing other alarms/conditions.

Are there other conditions/alarms in the alarm list?

If...	Then...
Yes	Proceed to the appropriate procedures to clear the alarms in order of severity. Then continue with the next step.
No	Proceed to Step 5.

From the System View, click the Alarm List button and click Refresh.

Is the inc. OCN RFI-L alarm still present?

If...	Then...
Yes	Continue with the next step.
No	STOP! End of Procedure.

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.

If faulty connections or damage...	Then...
was found,	Follow local procedures to repair/replace as necessary. Then continue with the next step.
was not found,	Proceed to Step 8.

From the System View, click the Alarm List button and click Refresh.

Is the inc. OCN RFI-L alarm still present?

If...	Then...
Yes	Continue with the next step.
No	STOP! End of Procedure.

Is the OLIU circuit pack equipped with pluggable transmission modules?

If...	Then...
Yes	Continue with the next step.
No	Proceed to Step 12.

NOTICE

Service-disruption hazard

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 6-8: Replace pluggable transmission module

From the System View, click the Alarm List button and click Refresh.

Is the inc. OCN RFI-L alarm still present?

If...	Then...
Yes	Remove the replacement pluggable transmission module and return the original pluggable transmission module to the socket, then continue with Step 12.

NOTICE

Service-disruption hazard

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 OCn circuit pack.

Reference:

From the System View, click the Alarm List button and click Refresh.

Is the inc. OCN RFI-L alarm still present?

If...	Then...
Yes	Remove the replacement OCn circuit pack and return the original circuit pack to the slot, then continue with Step 15.
No	STOP! End of Procedure.

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.

Follow local procedures for addressing OCN-related conditions/alarms at the far-end network element.

From the System View at the local network element, click the Alarm List button and click Refresh.

Is the inc. OCN RFI-L condition/alarm still present?

If...	Then...
Yes	Continue with Step 18.
No	STOP! End of Procedure.

Follow local procedures to isolate and clear the fiber/cable trouble between the far-end network element and the local network element.
