Chapter 2 Alarm Troubleshooting

Safety Summary

Minor alarms, such as the FSTSYNC alarm (see page 2-71), do not have a serious affect on service. FSTSYNC lets you know that the ONS 15327 is choosing a new timing reference because the old reference failed. The loss of the prior timing source is something a user needs to look at, but it should not immediately disrupt service.

Telcordia standard severities are the default settings for the ONS 15327. A user may customize

ONS 15327 alarm severities with the alarm profiles feature. For alarm profile procedures, refer to the Cisco ONS 15327 Procedure Guide.

This chapter lists the default alarm severity for the active reporting card, if applicable. The default severity for alarms reported by standby cards is always Minor, Non-Service-Affecting.

2.5 Safety Summary

This section covers safety considerations designed to ensure safe operation of the ONS 15327. Personnel should not perform any procedures in this chapter unless they understand all safety precautions, practices, and warnings for the system equipment. Some troubleshooting procedures require installation or removal of cards, in these instances users should pay close attention to the following caution and warnings:

Caution Hazardous voltage or energy might be present when the system is operating. Use caution when removing or installing cards.

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.

Warning Class 1 laser product.

Warning Class 1M laser radiation when open. Do not view directly with optical instruments.

2.6 Alarm Procedures

This section list alarms alphabetically and includes some conditions commonly encountered when troubleshooting alarms. The severity, description, and troubleshooting procedure accompany each alarm and condition.

Note When you check the status of alarms for cards, ensure that the alarm filter icon in the lower-right corner is not indented. If it is, click it to turn it off. When you are done checking for alarms, click the alarm filter icon again to turn filtering back on.
