c. Right-click to choose RESET CARD.
Step 30 Do a manual switch (side switch) of the cross-connect cards before retesting the circuit:
a. In the node view, select the Maintenance > XC Cards tabs.
b. From the Cross Connect Cards menu, choose Switch.
c. Click Yes on the Confirm Switch dialog box.
Note After the active cross-connect goes into standby, the original standby slot becomes active.
This causes the ACT/STBY LED to become green on the former standby card.
Step 31 Retest the circuit:
a. Resend test set traffic on the loopback circuit.
The test set traffic routes through the alternate cross-connect card.
b. Examine the test traffic received by the test set. Look for errors or any other signal information that
the test set is capable of indicating.
c. If the signal received by the test set is still faulty or non-existent, assume the cross-connect card is
not causing the problem. Skip to Step k of this procedure.
Step 32 If the circuit is now good, the problem could be a defective card. To confirm a defective original
cross-connect card:
a. Redo the manual switch (side switch) procedure to make the original active cross-connect card again
the active card.
b. Resend test set traffic on the loopback circuit.
c. If the signal received by the test set is still faulty or non-existent, return the defective card to Cisco.
Call the Technical Assistance Center (TAC) at 1-877-323-7368 to open an RMA case.
d. Replace the defective cross-connect card.
If the circuit is now good, the cross-connect card may have had a temporary problem that was
cleared by the side switch.
Step 33 Click the Circuits tab.
Step 34 Resend test set traffic on the loopback circuit.
The test set traffic routes through the alternate cross-connect card rather than the original cross-connect
card.
Step 35 Examine the received test set traffic. Look for errors or any other signal information that the test set is
capable of indicating.
Step 36 If the signal received by the test set is still faulty or non-existent, assume the problem does not lie in a
faulty cross-connect card and skip to Step 39 of this procedure.
Step 37 If the circuit is now good, the problem could be a defective card. To confirm a defective alternate
cross-connect card:
a. Repeat the manual switch (side switch) procedure to make the original active cross-connect card
again the active card.
b. Resend test set traffic on the loopback circuit.
c. If the signal received by the test set is still faulty or non-existent, return the defective card to Cisco.
Call the Technical Assistance Center (TAC) at 1-877-323-7368 to open an RMA case.
d. Replace the defective cross-connect card.
