Note For more information about Ethernet cards, refer to the Cisco ONS 15454 and
Cisco ONS 15454 SDH Ethernet Card Software Feature and Configuration Guide.
Clear the PDI-P Condition
Step 1 Verify that all circuits terminating in the reporting card are DISCOVERED:
a. Click the Circuits tab.
b. Verify that the Status column lists the circuit as active.
c. If the Status column lists the circuit as PARTIAL, wait 10 minutes for the ONS 15454 to initialize
fully. If the PARTIAL status 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 circuit is DISCOVERED, ensure that the signal source to the card reporting
the alarm is working.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15454.
Plug the wristband cable into the ESD jack located on the lower-right edge of the shelf assembly.
Step 3 If traffic is affected, complete the “Delete a Circuit” procedure on page 2-275.
Caution Deleting a circuit can affect existing traffic.
Step 4 Recreate the circuit with the correct circuit size. Refer to the “Create Circuits and VT Tunnels” chapter
in the Cisco ONS 15454 Procedure Guide for detailed procedures to create circuits.
Step 5 If circuit deletion and re-creation does not clear the condition, verify that there is no problem stemming
from the far-end OC-N card providing STS payload to the reporting card.
Step 6 If the condition does not clear, confirm the cross-connect between the OC-N card and the reporting card.
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 of the Cisco ONS 15454 Procedure
Guide.
Step 8 If the condition does not clear, complete the “Physically Replace a Traffic Card” procedure on
page 2-273 for the optical/electrical cards.
Step 9 If the condition does not clear, log into the Technical Support Website at
http://www.cisco.com/techsupport for more information or call Cisco TAC 1 800 553-2447.
