Chapter 2 Alarm Troubleshooting

Alarm Procedures

Step 4 Recreate the circuit with the correct circuit size. Refer to the Cisco ONS 15327 Procedure Guide for detailed procedures to create circuits.

Step 5 If circuit deletion and recreation does not clear the condition, verify that the far-end OC-N card providing STS payload to the reporting card is not errored.

Step 6 If the condition does not clear, confirm the cross-connect between the OC-N card and the reporting card.

Step 7 If the condition does not clear, clean the far-end optical fiber according to site practice. If no site practice exists, complete the procedure in the Cisco ONS 15327 Procedure Guide.

Step 8 If the condition does not clear, complete the “Physically Replace a Card” procedure on page 2-130for the optical/electrical cards.

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

Step 9 If the condition does not clear, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).

2.6.132 PEER-NORESPONSE

Major (MJ), Non-Service Affecting (NSA)

The Peer Card Not Responding (PEER-NORESPONSE) alarm is raised by the switch agent if either traffic card in a protection group does not receive a response to the peer status request message. PEER-NORESPONSE is a software failure and occurs at the task level, as opposed to a communication failure, which is a hardware failure between peer cards.

Procedure: Clear the PEER-NORESPONSE Alarm

Step 1 Complete the “Reset a Traffic Card in CTC” procedure on page 2-129for the protect card:

While the card resets, the FAIL LED on the physical card blinks and turns off.

While the card resets, the white LED with the letters “LDG” (loading) appears on the reset card in CTC.

Step 2 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 3 Complete the “Reset a Traffic Card in CTC” procedure on page 2-129for the working card:

While the card resets, the FAIL LED on the physical card blinks and turns off.

While the card resets, the white LED with the letters “LDG” appears on the reset card in CTC.

Step 4 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.
