d. Select the appropriate state (IS; OOS,DSBLD; OOS,MT; IS,AINS) in the Admin State column for
the port being tested.
e. Click Apply.
f. Click Yes in the confirmation dialog box.
Step 4 If the test set indicates a faulty circuit, the problem might be a faulty card.
Step 5 Complete the “Test the FC_MR Card” procedure on page 1-107.
Test the FC_MR Card
Step 1 Complete the “Physically Replace a Traffic Card” procedure on page 2-273 for the suspected bad card
and replace it with a known-good card.
Step 2 Resend test traffic on the loopback circuit with a known-good card.
Step 3 If the test set indicates a good circuit, the problem was probably the defective card. Return the defective
card to Cisco through the RMA process. Contact Cisco Technical Support at 1 800 553-2447.
Step 4 Complete the “Physically Replace a Traffic Card” procedure on page 2-273 for the defective card.
Step 5 Clear the terminal loopback on the port:
a. Double-click the source-node card with the terminal loopback.
b. Click the Maintenance > Loopback tabs.
c. Select None from the Loopback Type column for the port being tested.
d. Select the appropriate state (IS; OOS,DSBLD; OOS,MT; IS,AINS) in the Admin State column for
the port being tested.
e. Click Apply.
f. Click Yes in the confirmation dialog box.
The entire circuit path has now passed its comprehensive series of loopback tests. This circuit qualifies
to carry live traffic.
