1.4.3 Perform an XC Loopback on the Source Optical Port
Step 4 Complete the “Test the Standby Cross-Connect Card” procedure on page 1-55.
Test the Standby Cross-Connect Card
Note This procedure is performed only on cross-connect cards.
Step 1 Perform a reset on the standby cross-connect card:
a. Determine the standby cross-connect card. On both the physical node and the CTC node view
window, the standby cross-connect ACT/SBY LED is amber and the active card ACT/SBY LED is
green.
b. Position the cursor over the standby cross-connect card.
c. Right-click and choose RESET CARD.
d. Click Yes in the confirmation dialog box.
Step 2 Initiate an external switching command (side switch) on the cross-connect cards before you retest the
loopback circuit:
Caution Cross-connect side switches, with the exception of side switches using XC-VXC-10G cards, are
service-affecting. Any live traffic on any card in the node endures a hit of up to 50 ms. XC-VXC-10G side
switches are errorless.
a. Determine the standby cross-connect card. On both the physical node and the CTC node view
window, the standby cross-connect ACT/SBY LED is amber and the active card ACT/SBY LED is
green.
b. In the node view, select the Maintenance > Cross-Connect > Cards tabs.
c. In the Cross-Connect Cards area, click 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 3 Resend test traffic on the loopback circuit.
The test traffic now travels through the alternate cross-connect card.
Step 4 If the test set indicates a faulty circuit, assume the cross-connect card is not causing the problem. Clear
the XC loopback circuit:
a. Click the Circuits tab.
b. Choose the XC loopback circuit being tested.
c. Click Delete.
d. Click Yes in the Delete Circuits dialog box. Do not check any check boxes.
