Test the OC-N Controller Card | Cisco Systems ONS 15310-MA guide

Chapter 1 General Troubleshooting

1.6.3 Perform a Facility Loopback on an Intermediate-Node OC-N Port

Note It is normal for the “LPBKFACILITY (OCN)” condition on page 2-103. The condition clears when you remove the loopback.

Step 6 Complete the “Test and Clear the OC-N Facility Loopback Circuit” procedure on page 1-35.

Test and Clear the OC-N Facility Loopback Circuit

Step 1 If the test set is not already sending traffic, send test traffic on the loopback circuit.

Step 2 Examine the traffic received by the test set. Look for errors or any other signal information that the test set is capable of indicating.

Step 3 If the test set indicates a good circuit, no further testing is necessary with the facility loopback. Clear the facility loopback from the port:

a.Double-click the 15310-CL-CTX or CTX2500 card and click the Maintenance > Optical > Loopback > Port tabs.

b.Choose None from the Loopback Type column for the port being tested.

c.Choose the appropriate state (IS; OOS,DSBLD; OOS,MT) from the Admin State column for the port being tested.

d.Click Apply.

e.Click Yes in the confirmation dialog box.

Step 4 Clear the facility loopback circuit:

a.Click the Circuits tab.

b.Choose the loopback circuit being tested.

c.Click Delete.

d.Click Yes in the Delete Circuits dialog box. Do not check any check boxes.

Step 5 Complete the “Test the OC-N (Controller) Card” procedure on page 1-35.

Test the OC-N (Controller) Card

Step 1 Complete the “Physically Replace a Card” procedure on page 2-154for the suspected bad card and replace it with a known-good one.

Caution Removing a card that currently carries traffic on one or more ports can cause a traffic hit. To avoid this, perform an external switch if a switch has not already occurred. Refer to the procedures in the “2.10.1 Protection Switching, Lock Initiation, and Clearing” section on page 2-147. For more information, refer to the “Maintain the Node” chapter in the Cisco ONS 15310-CL and

Cisco ONS 15310-MA Procedure Guide.

Step 2 Resend test traffic on the loopback circuit with a known-good card installed.
