Chapter 2 Alarm Troubleshooting

Alarm Procedures

Procedure: Clear the CTNEQPT-PBPROT Alarm

Step 1 Perform a CTC reset on the standby XTC card. Complete the “Reset a Traffic Card in CTC” procedure on page 2-129. (The procedure is the same for the standby XTC as for the traffic card.)

Resetting the standby XTC card will not make it active. Verify that its LED is amber once the reset is complete.

If the cross-connect reset is not complete and error-free or if the XTC reboots automatically, call TAC (1-800-553-2447).

Step 2 If the alarm does not clear, complete the “Remove and Reinsert (Reseat) a Card” procedure on page 2-130for the standby XTC card.

Step 3 Determine whether the card is an active card or standby card in a protection group. Click the node view Maintenance > Protection tabs, then click the protection group. The cards and their status will be displayed in the list.

Step 4 If the reporting traffic card is the active card in the protection group, complete the “Switch Protection Group Traffic with an External Switching Command” procedure on page 2-127. After you move traffic off the active card, or if the reporting card is standby, continue with the following steps.

Step 5 Complete the “Reset a Traffic Card in CTC” procedure on page 2-129on the reporting card.

Step 6 When you reinsert the high-speed card, verify the following LED behavior:

The FAIL LED blinks for approximately 30 seconds.

All LEDs blink once and turn off.

The ACT/STBY LED is green (active).

Step 7 Verify that the reset is complete and error-free:

No new alarms appear in the Alarms window in CTC.

If you are looking at the physical ONS 15327, the ACT/STBY LED is illuminated.

If you are looking at the node view of the ONS 15327, an amber LED depiction with “Sby” has replaced the white “LDG” depiction on the card in CTC.

Step 8 If the alarm does not clear, complete the “Remove and Reinsert (Reseat) a Card” procedure on page 2-130for the reporting card.

Step 9 Complete the “Clear an External Switching Command” procedure on page 2-128.

Step 10 If the alarm does not clear, complete the “Remove and Reinsert (Reseat) a Card” procedure on page 2-130for the reporting card.

Step 11 If the alarm does not clear, complete the “Physically Replace a Card” procedure on page 2-130for the standby cross-connect card.

Note When replacing a card with an identical type of card, no additional CTC provisioning is required.

Step 12 If the alarm does not clear, complete the “Physically Replace a Card” procedure on page 2-130for the reporting traffic card.

Step 13 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC to report a service-affecting problem (1-800-553-2447).
