Chapter 2 Alarm Troubleshooting

Alarm Procedures

Clear the LOP-P Alarm

Step 1 In node view, click the Circuits tab and view the alarmed circuit.

Step 2 Verify the circuit size listed in the Size column. If the size is different from what is expected, such as an

STS3c instead of an STS1, this raises the alarm.

Step 3 If you have been monitoring the circuit with optical test equipment, a mismatch between the provisioned

circuit size and the size expected by the test set can cause this alarm. Ensure that the test set monitoring

is set up for the same size as the circuit provisioning.

For instructions to use the optical test set, consult the manufacturer.

Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15310-CL

or ONS 15310-MA.

Step 4 If the error is not due to an incorrectly configured test set, the error is in the provisioned CTC circuit

size. Complete the “Delete a Circuit” procedure on page 2-164.

Step 5 Recreate the circuit for the correct size. For procedures, refer to the “Create Circuits” chapter in the

Cisco ONS 15310-CL and Cisco ONS 15310-MA Procedure Guide.

Step 6 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport

for more information or call Cisco TAC (1-800-553-2447) in order to report a Service-Affecting (SA)

problem.

2.7.147 LOP-V

Default Severity: Major (MJ), Service-Affecting (SA)

SONET Logical Objects: VT-MON, VT-TERM

The LOP VT alarm indicates a loss of pointer at the VT level. This alarm can occur when the received

payload does not match the provisioned payload. LOP-V is caused by a circuit size mismatch on the

concatenation facility.

Clear the LOP-V Alarm

Step 1 Complete the “Clear the LOP-P Alarm” procedure on page 2-99.

Step 2 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport

for more information or call Cisco TAC (1-800-553-2447) in order to report a Service-Affecting (SA)

problem.

2.7.148 LO-RXPOWER

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

SONET Logical Object: OCN
