Chapter 1 General Troubleshooting

Troubleshooting Ethernet Circuit Paths With Loopbacks

c. From the Cross-Connect Cards menu, choose Switch.

d. Click Yes in the Confirm Switch dialog box.

Note After the active cross-connect goes into standby mode, the original standby card becomes

active and its ACT/SBY LED turns green. The former active card becomes standby and its

ACT/SBY LED turns amber.

Step 2 Resend test traffic on the loopback circuit.

Step 3 If the test set indicates a faulty circuit, the problem is probably the defective card. Return the defective

card to Cisco through the RMA process. Contact Cisco Technical Support at (1-800-553-2447) and

proceed to Step 4. If the test does not indicate a faulty circuit, proceed to Step 5.

Step 4 Complete the “2.10.3 Physical Card Reseating and Replacement” procedure on page 2-163 for the

defective card.

Step 5 If the test set indicates a good circuit, the cross-connect card might have had a temporary problem that

was cleared by the side switch. Clear the hairpin circuit:

a. Click the Circuits tab.

b. Choose the hairpin circuit being tested.

c. Click Delete.

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

e. Confirm that the hairpin circuit is deleted from the Circuits tab list.

Step 6 Complete the “1.6.4 Perform a Facility Loopback on an Intermediate-Node OC-N Port” procedure on

page 1-39.

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

Performing the facility loopback test on an intermediate node OC-N port (which carries the Ethernet

circuit) isolates whether this node is causing circuit failure. Complete the “Create a Facility Loopback

on an Intermediate-Node OC-N Port” procedure on page 1-39.

Note The CE100T-8 Ethernet card only supports point-to-point configurations and is not directly implicated

in the intermediate node testing.

Create a Facility Loopback on an Intermediate-Node OC-N Port

Step 1 Connect a test set to the OC-N port you are testing. If you are starting the current procedure without the

test set hooked up to the source port, use appropriate cabling to attach the Tx and Rx terminals of the

test set to the port you are testing. Both Tx and Rx connect to the same port.

Note For specific procedures to connect, set up, and use the test set equipment, consult the

manufacturer.
