Chapter 2 Alarm Troubleshooting

Alarm Procedures

Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15327. Plug the wristband cable into the ESD jack located between the top high-speed and XTC slots.

Procedure: Clear the RFI-V Condition

Step 1 Verify that the connectors are securely fastened and connected to the correct slot. For more information, refer to the Cisco ONS 15327 Procedure Guide.

Step 2 If connectors are correctly connected, verify that the XTC port is active and in service (IS):

a.Confirm that the OC-N card shows a green LED in CTC or on the physical card. A green LED indicates an active card. An amber LED indicates a standby card.

b.To determine whether the OC-N port is in service, double-click the card in CTC to display the card view.

c.Click the Provisioning > Line tabs.

d.Verify that the State column lists the port as IS.

e.If the State column lists the port as OOS, click the column and choose IS. Click Apply.

Step 3 If the ports are active and in service, use an optical test set to verify whether the signal source has errors.

For specific procedures to use the test set equipment, consult the manufacturer.

Step 4 If the signal is valid, log into the node at the far-end of the reporting ONS 15327.

Step 5 Clear alarms in the far-end node, especially an UNEQ-P alarm (see page 2-122)or an UNEQ-V alarm (see page 2-123).

Step 6 If the condition does not clear, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).

2.6.145 RING-MISMATCH

•Major (MJ), Service Affecting (SA)

A Procedural Error Mismatch Ring (RING-MISMATCH) alarm occurs when the ring ID of the

ONS 15327 that is reporting the alarm does not match the ring ID of another ONS node in the BLSR. ONS nodes connected in a BLSR must have identical ring IDs to function.

Procedure: Clear the RING-MISMATCH Alarm

Step 1 In node view, click the Provisioning > BLSR tabs.

Step 2 Note the number in the Ring ID field.

Step 3 Log into the next ONS node in the BLSR.

Step 4 Complete the “Identify a Ring ID or Node ID Number” procedure on page 2-125.

Step 5 If the ring ID matches the ring ID in the reporting ONS node, repeat Step 4 for the next ONS node in the BLSR.
