Clear "inc. BDI" alarms

Procedure 5-11: Clear "inc. BDI" alarms

Overview

This procedure is used to clear the following alarms:

inc. ODU2 BDI
inc. OTU2 BDI

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. BDI alarm.

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

Important!

The inc. BDI alarm indicates that the far-end network element has detected a bad ODU2/OTU2 signal from this network element. The trouble is in the local network element or in the fiber/cable between the local network element and the far-end network element. The inc. BDI alarm is normally cleared by addressing other alarms/conditions.

Are there other circuit pack/pluggable transmission module/ODU2/OTU2-related 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. BDI 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 XM10G/8 circuit pack faceplate/pluggable transmission module and the OMD circuit pack faceplate (if equipped), LGX panel, or equivalent connection point for faulty connections or damage.

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

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

Is the inc. BDI alarm still present?

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

Select View → OCH Cross-Connections to obtain the current list of OCH cross-connections for the required XM10G/8 circuit pack. Verify that the correct OCH cross-connections have been provisioned using office records.

If the correct OCH cross-connections...	Then...
have been provisioned,	Proceed to Step 11.
have not been provisioned,	Select Configuration → OCH Cross-Connections to access the OCH Cross-Connection Wizard and provision the required OCH cross-connections. Then continue with the next step.

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

Is the inc. BDI alarm still present?

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

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. BDI 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 the next step.
No	STOP! End of Procedure.

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 XM10G/8 circuit pack.

Reference:

Procedure 6-29: Replace 10G Muxponder circuit pack

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

Is the inc. BDI alarm still present?

If...	Then...
Yes	Remove the replacement XM10G/8 circuit pack and return the original circuit pack to the slot, then continue with the next step.
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 conditions/alarms at the far-end network element.

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

Is the inc. BDI alarm still present?

If...	Then...
Yes	Continue with the next step.
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.
