Chapter 2 Alarm Troubleshooting
2.5.5 Service Effect
2.5.5 Service Effect
Service-Affecting (SA) alarms—those that interrupt service—could be Critical (CR), Major (MJ), or
Minor (MN) severity alarms. Service-Affecting (SA) alarms indicate service is affected.
Non-Service-Affecting (NSA) alarms always have a Minor (MN) default severity.
2.5.6 States
The State column on the Alarms or History tabs indicates the disposition of the alarm or condition as
follows:
• A raised (R) event is one that is active.
• A cleared (C) event is one that is no longer active.
• A transient (T) event is one that is automatically raised and cleared in CTC during system changes
such as user login, logout, loss of connection to node view, etc. Transient events do not require user
action. These are listed in Chapter 3, “Transient Conditions.”
2.6 Safety Summary
This section provides safety considerations designed to ensure safe operation of the ONS 15310-CL and
ONS 15310-MA. Do not perform any procedures in this chapter unless you understand all safety
precautions, practices, and warnings for the system equipment. Some troubleshooting procedures
require installation or removal of cards; in these instances pay close attention to the following cautions
and warnings.

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.
