Chapter 2 Alarm Troubleshooting

Alarm Procedures

Warning

Invisible laser radiation could be emitted from the end of the unterminated fiber cable or connector.

Do not stare into the beam directly with optical instruments. Viewing the laser output with certain

optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of

100 mm could pose an eye hazard.

Statement 1056

Warning

Use of controls, adjustments, or performing procedures other than those specified could result in

hazardous radiation exposure.

Statement 1057

Clear the PLM-P Alarm

Step 1 Complete the “Clear the PDI-P Condition” procedure on page 2-122.

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.

2.7.190 PLM-V

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

SONET Logical Object: VT-TERM, VT-MON

A Payload Label Mismatch VT Layer alarm raises when the content of the V5 byte in the SONET

overhead is inconsistent or invalid. PLM-V occurs when ONS 15310-CLs or ONS 15310-MAs

interoperate with equipment that performs bit-synchronous mapping for DS-1 signal. The node uses

asynchronous mapping.

Clear the PLM-V Alarm

Step 1 Verify that your signal source matches the signal allowed by the traffic card. For example, the alarm will

occur if your signal source uses VT6 or VT9 mapping, because this is not supported by a

15310-CL-CTX, DS1-28/DS3-EC1-3, or DS1-84/DS3-EC1-3 card.

Step 2 If the signal source matches the card, verify that the SONET VT path originator is sending the correct

VT label value. You can find the SONET VT path originator using circuit provisioning steps.

Step 3 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.

2.7.191 PORT-MISMATCH

The PORT-MISMATCH alarm is not used in the ONS 15310 platforms in this release. It is reserved for

development.
