Chapter 2 Alarm Troubleshooting

Alarm Procedures

2.6.9 APSCM

•Major (MJ), Service Affecting (SA)

The APS Channel Mismatch (APSCM) alarm occurs when the ONS 15327 expects a working channel but receives a protection channel. In many cases, the working and protection channels are crossed and the protect channel is active. If the fibers are crossed and the working line is active, the alarm does not occur. The APSCM alarm occurs only on the ONS 15327 when bidirectional protection is used on OC-N cards in a 1+1 configuration.

Warning Invisible laser radiation might 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

mmmight pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified might result in hazardous radiation exposure.

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 APSCM Alarm

Step 1 Verify that the working-card channel fibers are physically connected directly to the adjoining node’s working-card channel fibers.

Step 2 If the fibers are correctly connected, verify that the protection-card channel fibers are physically connected directly to the adjoining node’s protection-card channel fibers.

Step 3 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC to report

aservice-affecting problem (1-800-553-2447).

2.6.10APSCNMIS

•Major (MJ), Service Affecting (SA)

The APS Node ID Mismatch (APSCNMIS) alarm occurs when the source node ID contained in the K2 byte of the incoming APS channel is not present in the ring map. The APSCNMIS alarm might occur and clear when a BLSR is being provisioned. If so, you can disregard the temporary occurrence. If the APSCNMIS remains, the alarm clears when a K byte with a valid source node ID is received.

Procedure: Clear the APSCNMIS Alarm

Step 1 Complete the “Identify a Ring ID or Node ID Number” procedure on page 2-125to verify that each node has a unique node ID number.

Step 2 If the Node ID column contains any two nodes with the same node ID listed, record the repeated node ID.

Step 3 Click Close in the Ring Map dialog box.
