Chapter 2 Alarm Troubleshooting

2.7.182 PDI-P

APDI-P condition reported on an OC-3 or OC-12 port supporting an ONS 15310-CL or ONS 15310-MA Ethernet card circuit could result from the end-to-end Ethernet link integrity feature of the Ethernet card. If the link integrity is the cause of the path defect, it is typically accompanied by the “CARLOSS (EQPT)” alarm on page 2-35reported against one or both Ethernet ports terminating the circuit. If this is the case, clear the TPTFAIL and CARLOSS alarms to resolve the PDI-P condition.

Warning Invisible laser radiation could be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm could pose an eye hazard. Statement 1056

Warning Use of controls, adjustments, or performing procedures other than those specified could result in hazardous radiation exposure. Statement 1057

Clear the PDI-P Condition

Step 1 Verify that all circuits terminating in the reporting card are in an active state by completing the following steps:

a.Click the Circuits tab.

b.Verify that the Status column lists the port as active.

c.If the Status column lists the port as incomplete, wait 10 minutes for the ONS 15310-CL or

ONS 15310-MA to initialize fully. If the incomplete state does not change after full initialization, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC to report a Service-Affecting (SA) problem (1-800-553-2447).

Step 2 After determining that the port is active, ensure that the signal source to the card reporting the alarm is working.

Step 3 If traffic is affected, complete the “Delete a Circuit” procedure on page 2-155.

Caution Deleting a circuit can affect existing traffic.

Step 4 Recreate the circuit with the correct circuit size. Refer to the “Create Circuits” chapter in the Cisco ONS 15310-CL and Cisco ONS 15310-MA Procedure Guide for procedures.

Step 5 If the circuit deletion and re-creation does not clear the condition, verify that there is no problem with the far-end OC-3 or OC-12 port providing STS payload to the reporting card.

Step 6 If the condition does not clear, confirm that the cross-connect between the OC-3 or OC-12 port and the reporting port is good.

Step 7 If the condition does not clear, clean the far-end optical fiber according to site practice. If no site practice exists, complete the procedure in the “Maintain the Node” chapter in the Cisco ONS 15310-CL and Cisco ONS 15310-MA Procedure Guide.

Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15310-CL or ONS 15310-MA.
