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 APSCM Alarm

Step 1 Verify that the working-port channel fibers are physically connected directly to the adjoining node

working-port channel fibers.

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

or ONS 15310-MA system.

Step 2 If the fibers are correctly connected, verify that the protection-port channel fibers are physically

connected directly to the adjoining node protection-port channel fibers.

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.

2.7.11 APSCNMIS

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

development.

2.7.12 APSIMP

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

SONET Logical Object: OCN

The APS Invalid Mode alarm occurs if a 1+1 protection group is not properly configured at both nodes

to send or receive the correct APS byte. A node that is either configured for no protection or is

configured for unidirectional path switched ring (UPSR) protection does not send the right K2 APS byte

anticipated by a system configured for 1+1 protection. The 1+1 protect port monitors the incoming K2

APS byte and raises this alarm if it does not receive the byte.

The alarm is superseded by an APSCM or APSMM alarm. It is not superseded by an AIS condition. It

clears when the port receives a valid code for 10 ms.
